South Asia
–
Topographically, it is dominated by the Indian Plate, which rises above sea level as Nepal and northern parts of India situated south of the Himalayas and the Hindu Kush. South Asia is bounded on the south by the Indian Ocean and on land by West Asia, Central Asia, East Asia, the current territories of Afghanistan, Bangladesh, Bhutan, Maldives, Nepal, India, Pakistan, and Sri Lanka form the countries of South Asia. The South Asian Association for Regional Cooperation is an economic cooperation organisation in the region which was established in 1985, South Asia covers about 5.1 million km², which is 11. 51% of the Asian continent or 3. 4% of the worlds land surface area. The population of South Asia is about 1.749 billion or about one fourth of the worlds population, overall, it accounts for about 39. 49% of Asias population and is home to a vast array of peoples. The area of South Asia and its extent is not clear cut as systemic. Aside from the region of South Asia, formerly part of the British Empire, there is a high degree of variation as to which other countries are included in South Asia. Modern definitions of South Asia are consistent in including Afghanistan, India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, Myanmar is included by some scholars in South Asia, but in Southeast Asia by others. Some do not include Afghanistan, others question whether Afghanistan should be considered a part of South Asia or the Middle East, the mountain countries of Nepal and Bhutan, and the island countries of Sri Lanka and Maldives are generally included as well. Myanmar is often added, and by various deviating definitions based on often substantially different reasons, the British Indian Ocean Territory, the common concept of South Asia is largely inherited from the administrative boundaries of the British Raj, with several exceptions. The Aden Colony, British Somaliland and Singapore, though administered at various times under the Raj, have not been proposed as any part of South Asia. Additionally Burma was administered as part of the Raj until 1937, the 562 princely states that were protected by but not directly ruled by the Raj became administrative parts of South Asia upon joining Union of India or Dominion of Pakistan. China and Myanmar have also applied for the status of members of SAARC. This bloc of countries include two independent countries that were not part of the British Raj – Nepal, and Bhutan, Afghanistan was a British protectorate from 1878 until 1919, after the Afghans lost to the British in the Second Anglo-Afghan war. The United Nations Statistics Divisions scheme of sub-regions include all eight members of the SAARC as part of Southern Asia, population Information Network includes Afghanistan, Bangladesh, Burma, India, Nepal, Pakistan and Sri Lanka as part of South Asia. Maldives, in view of its characteristics, was admitted as a member Pacific POPIN subregional network only in principle, the Hirschman–Herfindahl index of the United Nations Economic and Social Commission for Asia and the Pacific for the region includes only the original seven signatories of SAARC. The British Indian Ocean Territory is connected to the region by a publication of Janes for security considerations, the inclusion of Myanmar in South Asia is without consensus, with many considering it a part of southeast Asia and others including it within South Asia. Afghanistan was of importance to the British colonial empire, especially after the Second Anglo-Afghan War over 1878–1880, Afghanistan remained a British protectorate until 1919, when a treaty with Vladimir Lenin included the granting of independence to Afghanistan. Following Indias partition, Afghanistan has generally included in South Asia

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Body of water
–
A body of water or waterbody is any significant accumulation of water, generally on a planets surface. The term most often refers to oceans, seas, and lakes, a body of water does not have to be still or contained, Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. Most are naturally occurring geographical features, but some are artificial, there are types that can be either. For example, most reservoirs are created by engineering dams, similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways, some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans. The term body of water can also refer to a reservoir of water held by a plant, note that there are some geographical features involving water that are not bodies of water, for example waterfalls, geysers and rapids. Arm of the sea - also sea arm, used to describe a sea loch, arroyo - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, or seasonally. Artificial lake or artificial pond - see reservoir or impoundment, barachois - a lagoon separated from the ocean by a sand bar. Bay - an area of water bordered by land on three sides, similar to, but smaller than a gulf, bayou - a slow-moving stream or a marshy lake. Bight - a large and often only slightly receding bay, or a bend in any geographical feature, billabong - see Oxbow lake, a pond or still body of water created when a river changes course and some water becomes trapped. Boil - see Seep Brook - a small stream, canal - an artificial waterway, usually connected to existing lakes, rivers, or oceans. Channel - the physical confine of a river, slough or ocean consisting of a bed. See also stream bed and strait, earth scientists generally use the term to describe a circular or round inlet with a narrow entrance, though colloquially the term is sometimes used to describe any sheltered bay. Basin - a region of land where water from rain or snowmelt drains downhill into another body of water, such as a river, lake, creek - an inlet of the sea, narrower than a cove. Delta - the location where a river flows into an ocean, sea, estuary, lake, distributary or distributary channel - a stream that branches off and flows away from a main stream channel. Draw - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, fjord - a submergent landform which has occurred due to glacial activity. Glacier - a large collection of ice or a river that moves slowly down a mountain. Glacial Pothole - see Kettle Gulf - a part of a lake or ocean that extends so that it is surrounded by land on three sides, similar to, but larger than a bay, headland - an area of water bordered by land on three sides

Inflow (hydrology)
–
In hydrology, the inflow of a body of water is the source of the water in the body of water. It can also refer to the volume of incoming water in unit time. All bodies of water have multiple inflows, but often, one inflow may predominate, however, in many cases, no single inflow will predominate and there will be multiple primary inflows. For a lake, the inflow may be a river or stream that flows into the lake. Inflow may also be, strictly speaking, not flows, but rather precipitation, inflow can also be used to refer to groundwater recharge. The dictionary definition of inflow at Wiktionary

Indian Ocean
–
The Indian Ocean is the third largest of the worlds oceanic divisions, covering 70,560,000 km2. It is bounded by Asia on the north, on the west by Africa, on the east by Australia, the Indian Ocean is known as Ratnākara, the mine of gems in ancient Sanskrit literature, and as Hind Mahāsāgar, in Hindi. The northernmost extent of the Indian Ocean is approximately 30° north in the Persian Gulf, the oceans continental shelves are narrow, averaging 200 kilometres in width. An exception is found off Australias western coast, where the width exceeds 1,000 kilometres. The average depth of the ocean is 3,890 m and its deepest point is Diamantina Deep in Diamantina Trench, at 8,047 m deep, Sunda Trench has a depth of 7, 258–7,725 m. North of 50° south latitude, 86% of the basin is covered by pelagic sediments. The remaining 14% is layered with terrigenous sediments, glacial outwash dominates the extreme southern latitudes. The major choke points include Bab el Mandeb, Strait of Hormuz, the Lombok Strait, the Strait of Malacca, the Indian Ocean is artificially connected to the Mediterranean Sea through the Suez Canal, which is accessible via the Red Sea. All of the Indian Ocean is in the Eastern Hemisphere and the centre of the Eastern Hemisphere is in this ocean, marginal seas, gulfs, bays and straits of the Indian Ocean include, The climate north of the equator is affected by a monsoon climate. Strong north-east winds blow from October until April, from May until October south, in the Arabian Sea the violent Monsoon brings rain to the Indian subcontinent. In the southern hemisphere, the winds are milder. When the monsoon winds change, cyclones sometimes strike the shores of the Arabian Sea, the Indian Ocean is the warmest ocean in the world. Long-term ocean temperature records show a rapid, continuous warming in the Indian Ocean, Indian Ocean warming is the largest among the tropical oceans, and about 3 times faster than the warming observed in the Pacific. Research indicates that human induced greenhouse warming, and changes in the frequency, among the few large rivers flowing into the Indian Ocean are the Zambezi, Shatt al-Arab, Indus, Godavari, Krishna, Narmada, Ganges, Brahmaputra, Jubba and Irrawaddy River. The oceans currents are controlled by the monsoon. Two large gyres, one in the northern hemisphere flowing clockwise and one south of the equator moving anticlockwise, during the winter monsoon, however, currents in the north are reversed. Deep water circulation is controlled primarily by inflows from the Atlantic Ocean, the Red Sea, north of 20° south latitude the minimum surface temperature is 22 °C, exceeding 28 °C to the east. Southward of 40° south latitude, temperatures drop quickly, surface water salinity ranges from 32 to 37 parts per 1000, the highest occurring in the Arabian Sea and in a belt between southern Africa and south-western Australia

Drainage basin
–
A drainage basin or catchment area is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. Drainage basins connect into other drainage basins at elevations in a hierarchical pattern, with smaller sub-drainage basins. Other terms used to describe drainage basins are catchment, catchment basin, drainage area, river basin and water basin. In closed drainage basins the water converges to a point inside the basin, known as a sink, which may be a permanent lake. The drainage basin acts as a funnel by collecting all the water within the covered by the basin. Each drainage basin is separated topographically from adjacent basins by a perimeter, drainage basins are similar but not identical to hydrologic units, which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system. Hydrologic units are defined to allow multiple inlets, outlets, or sinks, in a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. Drainage basins of the oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans, the following is a list of the major ocean basins, About 48. 7% of the worlds land drains to the Atlantic Ocean. The two major mediterranean seas of the world also flow to the Atlantic, The Caribbean Sea and Gulf of Mexico basin includes most of the U. S. The Mediterranean Sea basin includes much of North Africa, east-central Africa, Southern, Central, and Eastern Europe, Turkey, and the areas of Israel, Lebanon. Just over 13% of the land in the world drains to the Pacific Ocean, the Indian Oceans drainage basin also comprises about 13% of Earths land. It drains the eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf, the Indian subcontinent, Burma, antarctica comprises approximately eight percent of the Earths land. The five largest river basins, from largest to smallest, are the basins of the Amazon, the Río de la Plata, the Congo, the Nile, and the Mississippi. The three rivers that drain the most water, from most to least, are the Amazon, Ganga, endorheic drainage basins are inland basins that do not drain to an ocean. Around 18% of all land drains to endorheic lakes or seas or sinks, the largest of these consists of much of the interior of Asia, which drains into the Caspian Sea, the Aral Sea, and numerous smaller lakes. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, in endorheic bodies of standing water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this is the Dead Sea, drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important

The country has 700 rivers and 8,046 km of inland waterways, highlands with evergreen forests are found in the northeastern and southeastern regions of the country. Bangladesh has many islands and a coral reef and it is home to the Sundarbans, the largest mangrove forest in the world. The countrys biodiversity includes a vast array of plant and wildlife, including critically endangered Bengal tigers, the Greeks and Romans identified the region as Gangaridai, a powerful kingdom of the historical subcontinent, in the 3rd century BCE. Archaeological research has unearthed several ancient cities in Bangladesh, which had trade links for millennia. The Bengal Sultanate and Mughal Bengal transformed the region into a cosmopolitan Islamic imperial power between the 14th and 18th centuries, the region was home to many principalities which had inland naval prowess. It was also a center of the worldwide muslin and silk trade. As part of British India, the region was influenced by the Bengali renaissance, the Partition of British India made East Bengal a part of the Dominion of Pakistan, and was renamed as East Pakistan. The region witnessed the Bengali Language Movement in 1952 and the Bangladesh Liberation War in 1971, after independence, a parliamentary republic was established. A presidential government was in place between 1975 and 1990, followed by a return to parliamentary democracy, the country has also been affected by poverty, natural disasters, hunger, dominant party systems and military coups.

India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

Situated between the Indian and Pacific oceans, it is the worlds largest island country, with more than seventeen thousand islands. At 1,904,569 square kilometres, Indonesia is the worlds 14th-largest country in terms of area and worlds 7th-largest country in terms of combined sea. It has an population of over 260 million people and is the worlds fourth most populous country. The worlds most populous island, Java, contains more than half of the countrys population, Indonesias republican form of government includes an elected legislature and president. Indonesia has 34 provinces, of which five have Special Administrative status and its capital and countrys most populous city is Jakarta, which is also the most populous city in Southeast Asia and the second in Asia. The country shares land borders with Papua New Guinea, East Timor, other neighbouring countries include Singapore, Vietnam, the Philippines, Australia, Palau, and the Indian territory of the Andaman and Nicobar Islands. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support the second highest level of biodiversity. The country has abundant natural resources like oil and natural gas, tin, copper, agriculture mainly produces rice, palm oil, tea, coffee, cacao, medicinal plants, spices and rubber. Indonesias major trading partners are Japan, United States, China, the Indonesian archipelago has been an important region for trade since at least the 7th century, when Srivijaya and then later Majapahit traded with China and India. Local rulers gradually absorbed foreign cultural, religious and political models from the early centuries CE, Indonesian history has been influenced by foreign powers drawn to its natural resources. Indonesia consists of hundreds of native ethnic and linguistic groups. The largest – and politically dominant – ethnic group are the Javanese, a shared identity has developed, defined by a national language, ethnic diversity, religious pluralism within a Muslim-majority population, and a history of colonialism and rebellion against it. Indonesias national motto, Bhinneka Tunggal Ika, articulates the diversity that shapes the country, Indonesias economy is the worlds 16th largest by nominal GDP and the 8th largest by GDP at PPP, the largest in Southeast Asia, and is considered an emerging market and newly industrialised country. Indonesia has been a member of the United Nations since 1950, Indonesia is a member of the G20 major economies and World Trade Organization. The name Indonesia derives from the Greek name of the Indós, the name dates to the 18th century, far predating the formation of independent Indonesia. In 1850, George Windsor Earl, an English ethnologist, proposed the terms Indunesians—and, his preference, in the same publication, one of his students, James Richardson Logan, used Indonesia as a synonym for Indian Archipelago. However, Dutch academics writing in East Indies publications were reluctant to use Indonesia, they preferred Malay Archipelago, the Netherlands East Indies, popularly Indië, the East, and Insulinde

Myanmar, officially the Republic of the Union of Myanmar and also known as Burma, is a sovereign state in South East Asia bordered by Bangladesh, India, China, Laos and Thailand. About one third of Myanmars total perimeter of 5,876 km, forms an uninterrupted coastline of 1,930 km along the Bay of Bengal, the countrys 2014 census revealed a much lower population than expected, with 51 million people recorded. Myanmar is 676,578 square kilometres in size and its capital city is Naypyidaw and its largest city and former capital city is Yangon. Early civilizations in Myanmar included the Tibeto-Burman-speaking Pyu city-states in Upper Burma, the Pagan Kingdom fell due to the Mongol invasions and several warring states emerged. In the 16th century, reunified by the Taungoo Dynasty, the country was for a period the largest empire in the history of Mainland Southeast Asia. The early 19th century Konbaung Dynasty ruled over an area included modern Myanmar and briefly controlled Manipur. The British invaded Myanmar after three Anglo-Burmese Wars in the 19th century and the became a British colony. Myanmar became an independent nation in 1948, initially as a nation and then, following a coup détat in 1962. For most of its independent years, the country has been engrossed in rampant ethnic strife, during this time, the United Nations and several other organisations have reported consistent and systematic human rights violations in the country. In 2011, the junta was officially dissolved following a 2010 general election. While former military leaders still wield enormous power in the country, there is, however, continuing criticism of the governments treatment of the Muslim Rohingya minority and its poor response to the religious clashes. In the landmark 2015 election, Aung San Suu Kyis party won a majority in both houses, Myanmar is a country rich in jade and gems, oil, natural gas and other mineral resources. In 2013, its GDP stood at US$56.7 billion, the income gap in Myanmar is among the widest in the world, as a large proportion of the economy is controlled by supporters of the former military government. As of 2016, according to the Human Development Index, Myanmar had a level of human development. The renaming remains a contested issue, many political and ethnic opposition groups and countries continue to use Burma because they do not recognise the legitimacy of the ruling military government or its authority to rename the country. The countrys official name is the Republic of the Union of Myanmar. Countries that do not officially recognise that name use the long form Union of Burma instead, in English, the country is popularly known as either Burma or Myanmar /ˈmjɑːnˌmɑːr/. Both these names are derived from the name of the majority Burmese Bamar ethnic group, Myanmar is considered to be the literary form of the name of the group, while Burma is derived from Bamar, the colloquial form of the groups name

Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia near south-east India. Sri Lanka has maritime borders with India to the northwest and the Maldives to the southwest, Sri Lankas documented history spans 3,000 years, with evidence of pre-historic human settlements dating back to at least 125,000 years. Its geographic location and deep harbours made it of strategic importance from the time of the ancient Silk Road through to World War II. Sri Lanka was known from the beginning of British colonial rule until 1972 as Ceylon, Sri Lankas recent history has been marred by a thirty-year civil war which decisively ended when the Sri Lankan military defeated the Liberation Tigers of Tamil Eelam in 2009. A diverse and multicultural country, Sri Lanka is home to many religions, ethnic groups, in addition to the majority Sinhalese, it is home to large groups of Sri Lankan and Indian Tamils, Moors, Burghers, Malays, Kaffirs and the aboriginal Vedda. Sri Lanka has a rich Buddhist heritage, and the first known Buddhist writings of Sri Lanka, Sri Lanka is a republic and a unitary state governed by a semi-presidential system. The legislative capital, Sri Jayawardenepura Kotte, is a suburb of the capital and largest city. Along with the Maldives, Sri Lanka is one of the two countries in South Asia that are rated among high human development on the Human Development Index. In antiquity, Sri Lanka was known to travellers by a variety of names, according to the Mahavamsa, the legendary Prince Vijaya named the land Tambapanni, because his followers hands were reddened by the red soil of the area. In Hindu mythology, such as the Mahabharata, the island was referred to as Lankā, in Tamil, the island is referred to as Eelam. Ancient Greek geographers called it Taprobanā or Taprobanē from the word Tambapanni, as a British crown colony, the island was known as Ceylon, it achieved independence as the Dominion of Ceylon in 1948. The country is known in Sinhalese as Śrī Laṃkā and in Tamil as Ilaṅkai, in 1972, its formal name was changed to Free, Sovereign and Independent Republic of Sri Lanka. Later in 1978 it was changed to the Democratic Socialist Republic of Sri Lanka, as the name Ceylon still appears in the names of a number of organisations, the Sri Lankan government announced in 2011 a plan to rename all those over which it has authority. The pre-history of Sri Lanka goes back 125,000 years, the era spans the Palaeolithic, Mesolithic and early Iron Ages. Among the Paleolithic human settlements discovered in Sri Lanka, Pahiyangala and it is said that Kubera was overthrown by his demon stepbrother Ravana, the powerful emperor who built a mythical flying machine named Dandu Monara. The modern city of Wariyapola is described as Ravanas airport, early inhabitants of Sri Lanka were probably ancestors of the Vedda people, an indigenous people numbering approximately 2,500 living in modern-day Sri Lanka. According to the Mahāvamsa, a written in Pāḷi, the original inhabitants of Sri Lanka are the Yakshas and Nagas. Ancient cemeteries that were used before 600BC and other signs of advanced civilization has also discovered in Sri Lanka

Bengali language
–
Bengali, also known by its endonym Bangla, is an Indo-Aryan language spoken in South Asia. With over 210 million speakers, Bengali is the seventh most spoken language in the world. Dominant in the last group was Persian, which was also the source of some grammatical forms, more recent studies suggest that the use of native and foreign words has been increasing, mainly because of the preference of Bengali speakers for the colloquial style. Today, Bengali is the language spoken in Bangladesh and the second most spoken language in India. Both the national anthems of Bangladesh and India were composed in Bengali, in 1952, the Bengali Language Movement successfully pushed for the languages official status in the Dominion of Pakistan. In 1999, UNESCO recognized 21 February as International Mother Language Day in recognition of the movement in East Pakistan. Language is an important element of Bengali identity and binds together a diverse region. Sanskrit was spoken in Bengal since the first millennium BCE, during the Gupta Empire, Bengal was a hub of Sanskrit literature. The Middle Indo-Aryan dialects were spoken in Bengal in the first millennium when the region was a part of the Magadha Realm and these dialects were called Magadhi Prakrit. They eventually evolved into Ardha Magadhi, Ardha Magadhi began to give way to what are called Apabhraṃśa languages at the end of the first millennium. Along with other Eastern Indo-Aryan languages, Bengali evolved circa 1000–1200 AD from Sanskrit, for example, Ardhamagadhi is believed to have evolved into Abahatta around the 6th century, which competed with the ancestor of Bengali for some time. Proto-Bengali was the language of the Pala Empire and the Sena dynasty, during the medieval period, Middle Bengali was characterized by the elision of word-final অ ô, the spread of compound verbs and Arabic and Persian influences. Bengali was a court language of the Sultanate of Bengal. Muslim rulers promoted the development of Bengali as part of efforts to Islamize. Bengali became the most spoken language in the Sultanate. This period saw borrowing of Perso-Arabic terms into Bengali vocabulary, major texts of Middle Bengali include Chandidas Shreekrishna Kirtana. The modern literary form of Bengali was developed during the 19th and early 20th centuries based on the dialect spoken in the Nadia region, a west-central Bengali dialect. Bengali presents a case of diglossia, with the literary

Andaman and Nicobar Islands
–
The Andaman and Nicobar Islands, one of the seven union territories of India, are a group of islands at the juncture of the Bay of Bengal and Andaman Sea. The territory is 150 km north of Aceh in Indonesia and separated from Thailand and it comprises two island groups, the Andaman Islands and the Nicobar Islands, separated by the 10°N parallel, with the Andamans to the north of this latitude, and the Nicobars to the south. The Andaman Sea lies to the east and the Bay of Bengal to the west, the territorys capital is the Andamanese town of Port Blair. The total land area of islands is approximately 8,249 km2. The capital of Nicobar Islands is Car Nicobar, the islands host the Andaman and Nicobar Command, the only tri-service geographical command of the Indian Armed Forces. The Andaman Islands are home to the only known Paleolithic people, the Sentinelese people, the earliest archaeological evidence yet documented goes back some 2,200 years. Since that time, the Andamanese have diversified into distinct linguistic, the Nicobar Islands appear to have been populated by people of various backgrounds. At the time of the European contact, the inhabitants were the Nicobarese people, speaking a Mon-Khmer language. Both are unrelated to the Andamanese, but being closely related to the Myanmarese, rajendra Chola I, one of the Tamil Chola dynasty kings, conquered the Andaman and Nicobar Islands to use them as a strategic naval base to launch a naval expedition against the Sriwijaya Empire. The islands also provided a maritime base for ships of the Maratha Empire in the 17th century. The Maratha navys admiral Kanhoji Angre established naval supremacy with a base in the islands and is credited with attaching those islands to India. The history of organised European colonisation on the islands began when the Danish settlers of the Danish East India Company arrived in the Nicobar Islands on 12 December 1755. On 1 January 1756, the Nicobar Islands were made a Danish colony, first named New Denmark, during 1754–1756 they were administrated from Tranquebar. The islands were abandoned due to outbreaks of malaria between 14 April 1759 and 19 August 1768, from 1787 to 1807/05,1814 to 1831,1830 to 1834. From 1 June 1778 to 1784, Austria mistakenly assumed that Denmark had abandoned its claims to the Nicobar Islands and attempted to establish a colony on them, renaming them Theresia Islands. In 1789 the British set up a base and penal colony on Chatham Island next to Great Andaman. Two years later the colony was moved to Port Cornwallis on Great Andaman, denmarks presence in the territory ended formally on 16 October 1868 when it sold the rights to the Nicobar Islands to Britain, which made them part of British India in 1869. In 1858 the British again established a colony at Port Blair, the primary purpose was to set up a penal colony criminal convicts from the Indian subcontinent

Sumatra
–
Sumatra is a large island in western Indonesia that is part of the Sunda Islands. It is the largest island that is entirely in Indonesia and the sixth-largest island in the world at 473,481 km2, Sumatra is an elongated landmass spanning a diagonal northwest-southeast axis. The Indian Ocean borders the west, northwest, and southwest sides of Sumatra with the chain of Simeulue, Nias. On the northeast side the narrow Strait of Malacca separates the island from the Malay Peninsula, on the southeast the narrow Sunda Strait separates Sumatra from Java. The northern tip of Sumatra borders the Andaman Islands, while on the eastern side are the islands of Bangka and Belitung, Karimata Strait. The Bukit Barisan mountains, which several active volcanoes, form the backbone of the island, while the northeast sides are outlying lowlands with swamps, mangrove. The equator crosses the island at its center on West Sumatra, the climate of the island is tropical, hot and humid with lush tropical rain forest once dominating the landscape. Sumatra was known in ancient times by the Sanskrit names of Swarnadwīpa and Swarnabhūmi, the first word mentioning the name of Sumatra was the name of Srivijayan Haji Sumatrabhumi, who sent an envoy to China in 1017. Arab geographers referred to the island as Lamri in the tenth through thirteenth centuries, late in the 14th century the name Sumatra became popular in reference to the kingdom of Samudra Pasai, which was a rising power until it was replaced by Sultanate of Aceh. Sultan Alauddin Shah of Aceh, on letters written in 1602 addressed to Queen Elizabeth I of England, referred to himself as king of Aceh, the word itself is from Sanskrit Samudra, meaning gathering together of waters, sea or ocean. European writers in the 19th century found that the inhabitants did not have a name for the island. The Melayu Kingdom was absorbed by Srivijaya, Srivijaya was a Buddhist monarchy centred in what is now Palembang. Dominating the region trade and conquest throughout the 7th to 9th centuries. The empire was a thalassocracy or maritime power that extended its influence from island to island, Palembang was a center for scholarly learning, and it was there the Chinese Buddhist pilgrim I Ching studied Sanskrit in 671 CE before departing for India. On his journey to China, he spent four years in Palembang translating Buddhist texts, Srivijayan influence waned in the 11th century after it was defeated by the Chola Empire of southern India. At the same time, Islam made its way to Sumatra through Arabs, by the late 13th century, the monarch of the Samudra kingdom had converted to Islam. Marco Polo visited the island in 1292, and Ibn Battuta visited twice during 1345–1346, Samudra was succeeded by the powerful Aceh Sultanate, which survived to the 20th century. With the coming of the Dutch, the many Sumatran princely states fell under their control

Bay
–
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, lake, or another bay. A large bay may be called a gulf, sea, sound, a cove is a type of smaller bay with a circular inlet and narrow entrance. A fjord is a particularly steep bay shaped by glacial activity, bays can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River, which is the largest bay in North America. Bays may also be nested within each other, for example, some large bays, such as the Bay of Bengal and the Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds, bays were significant in the history of human settlement because they provided a safe place for fishing. Later they were important in the development of sea trade as the safe anchorage they provide encouraged their selection as ports, there are various ways from which bays can be created. The largest bays have developed as a result of plate tectonics, as the super-continent Pangaea broke up along curved and indented fault lines, the continents moved apart and the worlds largest bays formed. These include the Gulf of Guinea, Gulf of Mexico and the Bay of Bengal, another way bays form is via glacial and river erosion. A bay formed by a glacier is a fjord, rias are created by rivers and are characterised by more gradual slopes. Currents can make waves more constant, and soft rocks speed erosion, hard rock eroded less quickly, leaving headlands. The Gulf of California is an example of a bay created by plate tectonics as Baja California peninsula moves away from the Mexican mainland, Bay platform Great capes Headlands and bays

Southeast Asia
–
Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the countries that are geographically south of China, east of India, west of New Guinea and north of Australia. The region lies near the intersection of geological plates, with seismic and volcanic activity. Southeast Asia consists of two regions, Mainland Southeast Asia, also known historically as Indochina, comprising Vietnam, Laos, Cambodia, Thailand, Myanmar. Maritime Southeast Asia, comprising Indonesia, East Malaysia, Singapore, Philippines, East Timor, Brunei, Cocos Islands, definitions of Southeast Asia vary, but most definitions include the area represented by the countries listed below. All of the states are members of the Association of Southeast Asian Nations, the area, together with part of South Asia, was widely known as the East Indies or simply the Indies until the 20th century. Sovereignty issues exist over some territories in the South China Sea, Papua New Guinea has stated that it might join ASEAN, and is currently an observer. Southeast Asia is geographically divided into two subregions, namely Mainland Southeast Asia and Maritime Southeast Asia, Mainland Southeast Asia includes, Maritime Southeast Asia includes, The Andaman and Nicobar Islands of India are geographically considered part of Southeast Asia. Eastern Bangladesh and the Seven Sister States of India are culturally part of Southeast Asia, the eastern half of Indonesia and East Timor are considered to be biogeographically part of Oceania. Homo sapiens reached the region by around 45,000 years ago, homo floresiensis also lived in the area up until 12,000 years ago, when they became extinct. Austronesian people, who form the majority of the population in Indonesia, Malaysia, Brunei, East Timor. Solheim and others have shown evidence for a Nusantao maritime trading network ranging from Vietnam to the rest of the archipelago as early as 5000 BC to 1 AD. The peoples of Southeast Asia, especially those of Austronesian descent, have been seafarers for thousands of years and their vessels, such as the vinta, were ocean-worthy. Magellans voyage records how much more manoeuvrable their vessels were, as compared to the European ships, Passage through the Indian Ocean aided the colonisation of Madagascar by the Austronesian people, as well as commerce between West Asia and Southeast Asia. Gold from Sumatra is thought to have reached as far west as Rome and this was later replaced by Hinduism. Theravada Buddhism soon followed in 525, in the 15th century, Islamic influences began to enter. This forced the last Hindu court in Indonesia to retreat to Bali, in Mainland Southeast Asia, Burma, Cambodia and Thailand retained the Theravada form of Buddhism, brought to them from Sri Lanka. This type of Buddhism was fused with the Hindu-influenced Khmer culture, very little is known about Southeast Asian religious beliefs and practices before the advent of Indian merchants and religious influences from the 2nd century BCE onwards. Prior to the 13th century CE, Hinduism and Buddhism were the religions in Southeast Asia

Ganges
–
The Ganges, also Ganga is a trans-boundary river of Asia which flows through the nations of India and Bangladesh. It is the third largest river in the world by discharge, the Ganges is the most sacred river to Hindus. It is also a lifeline to millions of Indians who live along its course and it is worshipped as the goddess Ganga in Hinduism. It has also important historically, with many former provincial or imperial capitals located on its banks. The Ganges was ranked as the fifth most polluted river of the world in 2007, pollution threatens not only humans, but also more than 140 fish species,90 amphibian species and the endangered Ganges river dolphin. The levels of fecal coliform from human waste in the waters of the river near Varanasi are more than 100 times the Indian governments official limit. The main stem of the Ganges begins at the confluence of the Bhagirathi, the Bhagirathi is considered to be the source in Hindu culture and mythology, although the Alaknanda is longer, and, therefore, hydrologically the source stream. The headwaters of the Alakananda are formed by snowmelt from such peaks as Nanda Devi, Trisul, although many small streams comprise the headwaters of the Ganges, the six longest and their five confluences are considered sacred. The six headstreams are the Alaknanda, Dhauliganga, Nandakini, Pindar, Mandakini, the five confluences, known as the Panch Prayag, are all along the Alaknanda. After flowing 250 km through its narrow Himalayan valley, the Ganges emerges from the mountains at Rishikesh, the Ganges follows an 800 km arching course passing through the cities of Kannauj, Farukhabad, and Kanpur. Along the way it is joined by the Ramganga, which contributes an annual flow of about 500 m3/s. The Ganges joins the Yamuna at the Triveni Sangam at Allahabad, at their confluence the Yamuna is larger than the Ganges, contributing about 2,950 m3/s, or about 58. 5% of the combined flow. Now flowing east, the river meets the Tamsa River, which flows north from the Kaimur Range, after the Tamsa the Gomti River joins, flowing south from the Himalayas. The Gomti contributes an annual flow of about 234 m3/s. Then the Ghaghara River, also flowing south from the Himalayas of Nepal, the Ghaghara, with its average annual flow of about 2,990 m3/s, is the largest tributary of the Ganges. After the Ghaghara confluence the Ganges is joined from the south by the Son River, the Gandaki River, then the Kosi River, join from the north flowing from Nepal, contributing about 1,654 m3/s and 2,166 m3/s, respectively. The Kosi is the third largest tributary of the Ganges, after the Ghaghara and Yamuna. Along the way between Allahabad and Malda, West Bengal, the Ganges passes the towns of Chunar, Mirzapur, Varanasi, Ghazipur, Patna, Bhagalpur, Ballia, Buxar, Simaria, Sultanganj, and Saidpur

Hooghly River
–
The Hooghly River or the Bhāgirathi-Hooghly, called Ganga traditionally, is an approximately 260-kilometre-long distributary of the Ganges River in West Bengal, India. It splits from the Ganges as a canal in Murshidabad District at the Farakka Barrage, the town of Hugli-Chinsura, formerly Hooghly, is located on the river, in the Hooghly. The origins of the Hooghly name are uncertain, whether the city or the river was named first, the Farakka Barrage is a dam that diverts water from the Ganges into a canal near the town of Tildanga in Murshidabad district. This supplies the Hooghly with adequate water even in the dry season and it parallels the Ganges, past Dhulian, until just above Jahangirpur where the canal ends and the river takes its own course. Just south of Jahangirpur it leaves the Ganges area and flows south past Jiaganj Azimganj, Murshidabad, the river then flows south past Katwa, Navadwip and Kalna. At Kalna it originally formed the border between Nadia District and Hooghly District, and then further south between Hooghly District and North 24 Parganas District and it flows past Halisahar, Chinsurah, Serampore, and Kamarhati. Then just before entering the cities of Kolkata and Howrah. At Nurpur it enters an old channel of the Ganges and turns south to empty into the Bay of Bengal through the estuary of about 20 mi wide, two of its primary tributaries are Damodar and Rupnarayan. The tide runs rapidly on the Hooghly, and produces an example of the fluvial phenomenon known as a tidal bore. This consists of the head-wave of the tide, hemmed in where the estuary narrows suddenly into the river. It is felt as high up as Kolkata, and frequently destroys small boats, the difference from the lowest point of low-water in the dry season to the highest point of high-water in the rains is reported to be 20 ft 10 in. The greatest mean rise of tide, about 16 ft, takes place in March, April or May - with a declining range during the season to a mean of 10 ft. In its upper reaches the river is known as the Bhāgirathi. In 1974, the Farakka Barrage began diverting water into the Hooghly during the dry season so as to reduce the difficulties at Kolkatas port. Like the rest of the Ganges, the Bhāgirathi-Hooghly is considered sacred to Hindus, the Bhāgirathi-Hooghly river system is an essential lifeline for the people of West Bengal. It was through this river that the East India company sailed into Bengal and established their settlement, Calcutta. People from other such as the French, Dutch, Portuguese. The river provides a supply of water to the plain of West Bengal for irrigation

Padma River
–
The Padma is a major river in Bangladesh. It is the main distributary of the Ganges, flowing generally southeast for 120 kilometres to its confluence with the Meghna River near the Bay of Bengal, the city of Rajshahi is situated on the banks of the river. The Padma, Sanskrit for lotus flower, is mentioned in Hindu mythology as a byname for the Goddess Lakshmi. The name Padma is given to the part of the course of the Ganges below the point of the off-take of the Bhagirathi River, another Ganges River distributary also known as the Hooghly River. Padma had, most probably, flowed through a number of channels at different times, the places mentioned by Rennell proceeding from west to east are Rampur Boali, the headquarters of Rajshahi district, Puthia and Natore in the same district and Jaffarganj in the district of Dhaka. The place last named were shown in a map of the Mymensingh district dated 1861, as a subdistrict headquarters and it is now known as Payla Jaffarganj and is close to Elachipur opposite Goalunda. According to Rennells theory, therefore, the former course of the Ganges would correspond with that of the present channel of the Baral River. Authorities agree that the Ganges has changed its course and that at different times, the bed of the Padma is wide, and the river is split up into several channels flowing between constantly shifting sand banks and islands. During the rains the current is strong and even steamers may find difficulty in making headway against it. It is navigable at all seasons of the year by steamers and country boats of all sizes and it is spanned near Paksey by the great Hardinge Bridge over which runs one of the main lines of the Bangladesh Railway. Rajshahi, a city in western Bangladesh, is situated on the north bank of the Padma. The Ganges originates in the Gangotri Glacier of the Himalaya, and runs through India, the Ganges enters Bangladesh at Shibganj in the district of Chapai Nababganj. West of Shibganj, the Ganges branches into two distributaries, the Bhagirathi and the Padma rivers, the Bhagirathi River, which flows southwards, is also known as the Ganga and was named the Hoogly or Hooghly River by the British. Further downstream, in Goalando,2,200 kilometres from the source, the Padma is joined by the Jamuna and the resulting combination flows with the name Padma further east, to Chandpur. Here, the widest river in Bangladesh, the Meghna joins the Padma, continuing as the Meghna almost in a line to the south. The Padma forms the whole of the boundary of the Pabna District for a distance of about 120 kilometres. Rajshahi is the largest city among the cities which is situated on the bank of Padma river and it is the third largest city in Bangladesh. It is a city in the north Bengal

Brahmaputra River
–
The Brahmaputra (/ˌbrɑːməˈpuːtrə/ is one of the major rivers of Asia, a trans-boundary river which flows through China, India and Bangladesh. As such, it is known by names in the region. It is also called Tsangpo-Brahaputra, and the Jamuna River in Bangladesh, the Manas River that runs through Bhutan joins it at Jogighopa, in India. It is the tenth largest river in the world by discharge, and it flows southwest through the Assam Valley as Brahmaputra and south through Bangladesh as the Jamuna. About 1,800 mi long, the Brahmaputra is an important river for irrigation and transportation, the average depth of the river is 124 ft and maximum depth is 380 ft. The river is prone to flooding in spring when the Himalayan snows melt. The average discharge of the river is about 19,300 m3/s and it is a classic example of a braided river and is highly susceptible to channel migration and avulsion. It is also one of the few rivers in the world exhibit a tidal bore. It is navigable for most of its length, the basin, especially south of Tibet, is characterized by high levels of rainfall. Kangchenjunga is the peak above 8,000 m, hence is the highest point within the Brahmaputra basin. The Brahmaputras upper course was long unknown, and its identity with the Yarlung Tsangpo was only established by exploration in 1884–86 and this river is often called Tsangpo-Brahmaputra river. The lower reaches are sacred to Hindus, while most rivers on the Indian subcontinent have female names, this river has a rare male name, as it means son of Brahma in Sanskrit. Assam govt is set to celebrate the beauty of the mighty river as Namami Brahmaputra- this international event will be organised across 21 districts of Assam from 31 March to April 42017. The Brahmaputra River, called Yarlung Tsangpo in Tibetan language, originates on the Chemayungdung Glacier located on the side of the Himalayas in Burang County of Tibet.73 million km2. From its source, the runs for nearly 1,100 km in a generally easterly direction between the main range of the Himalayas to the south and the Kailas Range to the north. Throughout its upper course, the river is known as the Tsangpo, it is also known by its Chinese name. In Tibet, the Tsangpo receives a number of tributaries, the most important left-bank tributaries are the Raka Zangbo, which joins the river west of Xigazê, and the Lhasa, which flows past the Tibetan capital of Lhasa and joins the Tsangpo at Qüxü. The Nyang Qu River joins the river from the north at Zela, on the right bank, a second river called the Nyang Qu meets the Tsangpo at Xigazê

Jamuna River (Bangladesh)
–
The Jamuna River is one of the three main rivers of Bangladesh. It is the main channel of the Brahmaputra River as it flows from India to Bangladesh. The Jamuna flows south and joins the Padma River, near Goalundo Ghat and it then flows into the Bay of Bengal as the Meghna River. The Brahmaputra-Jamuna is an example of a braided river and is highly susceptible to channel migration and avulsion. It is characterised by a network of interlacing channels with numerous sandbars enclosed between them, the sandbars, known in Bengali as chars, do not occupy a permanent position. The river deposits them in one year, very often to be destroyed later, the breaking of a char or the emergence of a new one is also a cause of much violence and litigation. It is the National river of Bangladesh, in Bangladesh, the Brahmaputra is joined by the Teesta River, one of its largest tributaries. The Teesta earlier ran due south from Jalpaiguri in three channels, namely, the Karatoya to the east, the Punarbhaba in the west, the three channels possibly gave the name to the river as Trisrota possessed of three streams which has been shortened and corrupted to Teesta. Of these three, the Punarbhaba joined the Mahananda, the Atrai passing through a vast marshy area known as Chalan Beel joined the Karatoya and the united stream joined the Padma near Jafarganj. In the destructive floods of 1787, the Teesta river forsook its old channel, james Rennell made a survey between 1764 and 1777 and his maps are one of the earliest authentic maps of Bengal in existence. In these maps Teesta is shown as flowing through North Bengal in several branches — Punarbhaba, Atrai, Karatoya, below the Teesta, the Brahmaputra splits into two distributary branches. The western branch, which contains the majority of the flow, continues due south as the Jamuna to merge with the lower Ganges. The eastern branch, formerly the larger but now smaller, is called the lower or old Brahmaputra. It curves southeast to join the Meghna River near Dhaka, the Padma and Meghna converge near Chandpur and flow out into the Bay of Bengal. This final part of the river is called Meghna, in the past the course of the lower Brahmaputra was different and passed through the Jamalpur and Mymensingh districts. The Jamuna is a wide river. During the rains it is about 5–8 miles from bank to bank, even during the dry season when the waters subside, the breadth is hardly less than 2–3 miles. The Jamuna was a barrier in establishing a road link between capital Dhaka and northern part of Bangladesh, better known as Rajshahi Division, until 1996

Barak River
–
The Barak River is one of the major rivers of South Assam and is a part of the Surma-Meghna River System. It rises in the country of Manipur State, where it is the biggest. After Manipur it flows through Mizoram State and into Assam, ending just after it enters Bangladesh where the Surma, from its source in the Manipur Hills of India, Liyai Village of Poumai Naga tribe, the river is known as the Barak River. Near its source, the river receives a lot of little streams, including the Gumti, Howrah, Kagni, Senai Buri, Hari Mangal, Kakrai, Kurulia, Balujhuri, Shonaichhari. It flows west through Manipur State, then southwest leaving Manipur and it then flows west past the town of Silchar where it is joined by the Madhura River. After Silchar, it flows for about 30 kilometres, and just west of Badarpur it enters Bangladesh and at its mouth divides into the Surma River, List of rivers of India List of rivers of Bangladesh

Surma River
–
The Surma River is a major river in Bangladesh, part of the Surma-Meghna River System. It starts when the Barak River from northeast India divides at the Bangladesh border into the Surma and it ends in Kishoreganj District, above Bhairab Bāzār), where the two rivers rejoin to form the Meghna River. The waters from the river flow into the Bay of Bengal. The average depth of river is 282 feet and maximum depth is 550 feet, from its source in the Manipur Hills near Mao Songsang, the river is known as the Barak River. At the border with Bangladesh, the divides with the northern branch being called the Surma River. This is where the river enters the Sylhet Depression which forms the Surma Basin, the Surma is fed by tributaries from the Meghalaya Hills to the north, and is also known as the Baulai River after it is joined by the south-flowing Someshwari River. The Kushiyara receives tributaries from the Sylhet Hills and Tripura Hills to the south, the Kushiyara is also known as the Kalni River after it is joined by a major offshoot from the Surma. When the Surma and the Kushiyara finally rejoin in Kishoreganj District above Bhairab Bazar, the Surma passes through many haors. In Islam, Sirajul, Jamal, Ahmed A.

Meghna River
–
The Meghna River is one of the most important rivers in Bangladesh, one of the three that forms the Ganges Delta, the largest delta on earth fanning out to the Bay of Bengal. The Meghna meets its tributary, the Padma, in Chandpur District. Other major tributaries of the Meghna include the Dhaleshwari, the Gumti, the Meghna empties into the Bay of Bengal in Bhola District via four principal mouths, named Tetulia, Shahbazpur, Hatia, and Bamni. The Meghna is the widest river among those that flow completely inside the boundaries of Bangladesh, at a point near Bhola, Meghna is 12 km wide. In its lower reaches this river follows almost a straight line in its path, the Meghna is formed inside Bangladesh by the joining of the Surma and Kushiyara rivers originating from the hilly regions of eastern India. Down to Chandpur, Meghna is hydrographically referred to as the Upper Meghna, after the Padma joins, it is referred to as the Lower Meghna. Near Muladhuli in Barisal district, the Safipur River is an offshoot of the Surma that creates one of the rivers in South Bengal. 1.5 km wide, this river is one of the widest in the country as well. At Ghatalpur of Brahmanbaria District, the river Titas emerges from Meghna, the Titas forms as a single stream but braids into two distinct streams which remain separate before re-joining the Meghna. In Daudkandi, the Meghna is joined by the Gumti River, the pair of bridges over the Meghna and Gumti are two of the countrys largest bridges. Meghna is again reinforced by the Dhaleshwari before Chandpur and this peculiarity of the river is always a great attraction for people. All of these rivers rejoin the Meghna at different points downstream, near Bhola, just before flowing into the Bay of Bengal, the river again divides into two main streams in the Ganges delta and separates an island from both sides of the mainland. The western stream is called Ilsha while the one is called Bamni

Irrawaddy River
–
The Irrawaddy River or Ayeyarwady River is a river that flows from north to south through Myanmar. It is the countrys largest river and most important commercial waterway, originating from the confluence of the Nmai and Mali rivers, it flows relatively straight North-South before emptying through the Irrawaddy Delta into the Andaman Sea. Its drainage basin of about 404,200 square kilometres covers a part of Burma. After Rudyard Kiplings poem, it is referred to as The Road to Mandalay. As early as the century the river was used for trade. Having developed a network of irrigation canals, the river became important to the British Empire after it had colonized Burma. The river is still as vital today, as an amount of goods. Rice is produced in the Irrawaddy Delta, irrigated by water from the river, environmental organisations have raised concerns about the ecological impacts on the rivers biodiverse ecosystems. Animals potentially impacted include the threatened Irrawaddy dolphin and the Irrawaddy river shark, the native Kachin people named the river Mali-Nmai-Hka. The Burmese name of Irrawaddy is derived from a Pali name for the Ravi River of India, airavati was the Pali version of the name of the elephant mount of Sakka, an important deva in Buddhism. Elephants were often a symbol for water and was used as the name for several others rivers, the Irrawaddy gives its name to the Irrawaddy dolphin, which is found in the lower reaches of the river and known to help fishermen who practice cast-net fishing. Though called Irrawaddy dolphin, it has also found in the Bay of Bengal. The Irrawaddy River bisects Myanmar from north to south and empties through the nine-armed Irrawaddy Delta into the Indian Ocean, the Irrawaddy River arises by the confluence of the Nmai and Mali Rivers in Kachin State. Both the Nmai and Mali Rivers find their sources in the Himalayan glaciers of Upper Burma near 28° N, the eastern branch of the two, Nmai, is the larger and rises in the Languela Glacier north of Putao. It is unnavigable because of the strong current whereas the western branch. Herefore, the Mali river is called by the same name as the main river by locals. The controversial Myitsone Dam is currently under construction at the convergence of these rivers, the city of Myitkyina lies 50 kilometres south of the confluence and can be reached during the dry season. Between Myitkyina and Mandalay, the Irrawaddy flows through three well-marked defiles, About 65 kilometres downstream from Myitkyinā is the first defile, below Bhamo the river makes a sharp westward swing, leaving the Bhamo alluvial basin to cut through the limestone rocks of the second defile

Godavari River
–
The Godavari is the second longest river in India after the river Ganges having its source at Tryambakeshwar, Maharashtra. Measuring up to 312,812 km2, it one of the largest river basins in the Indian subcontinent, with only the Ganges. However, in the past few decades, the river has been abused with relentless construction of barrages and dams. The river delta, supporting 729 persons/km2 – nearly twice the density average for the nation, has been categorized as having substantial risk to greater risk of flooding with rising sea levels. The Godavari originates 80 km from the Arabian Sea in the Western Ghats of central India near Nasik in Maharashtra. The Godavari River has an area of 312,812 km2. The river basin is considered to be divided into 3 sections, Upper, Middle and these put together account for 24. 2% of the total basin area. The rivers annual average water inflows are nearly 110 billion cubic metres, nearly 50% of the water availability is being harnessed. The water allocation from the river among the states are governed by the Godavari Water Disputes Tribunal. The river has highest flood flows in India and experienced recorded flood of 3.6 million cusecs in the year 1986, within Nashik District the river assumes a north-easterly course till it flows into the Gangapur Reservoir created by a dam of the same name. The reservoir along with the Kashypi Dam provides potable water to Nashik, about 25 km below Nasik is the confluence of the Godavari and one of its tributaries, the Darna river. The stream occupies, for nine months in the year, a space in a wide and gravelly bed. A few kilometres after its meeting with the Darna, the Godavari swerves to the north-east, till the Banganga, from the north-west, the course of the main stream then tends more decidedly south. At Nandur-Madhmeshwar, the Kadva, a large affluent, brings considerable increase to the waters of the Godavari. The river begins its southeasterly course characteristic of rivers of the Deccan Plateau, the river beyond exits the Niphad Taluka of Nashik and enter the Kopargaon taluka, Ahmednagar District. Within Ahmednagar the river completes its short course, flowing alongside the town of Kopargaon. By virtue of a sub-tributary of Pravara – Mandohol, which originates in Pune District – the basin impinges the Pune District, the river at Paithan has been impounded by the Jayakwadi Dam forming the NathSagar Reservoir. Kalsubai located in Godavari basin, is the highest peak in Maharashtra, Beed and Jalna Beed and Parbhani, Located along here is its merger with Sindphana, an important tributary which drains a considerably large area within Beed

Mahanadi
–
The Mahanadi is a major river in East Central India. It drains an area of around 141,600 square kilometres and has a course of 858 kilometres. The river flows through the states of Chhattisgarh and Odisha. The word Mahanadi literally comes from two odia words maha and nadi meaning The Great River. Like many other seasonal Indian rivers, the Mahanadi too is a combination of mountain streams. However its farthest headwaters lie 6 kilometres from Pharsiya village 442 metres above sea level south of Nagri town in Dhamtari district of Chhattisgarh, the hills here are an extension of the Eastern Ghats and are a source of many other streams which then go on to join the Mahanadi. For the first 80 kilometres of its course, the Mahanadi flows in a direction and drains the Raipur district. It is a narrow river at this stage and the total width of its valley does not exceed 500–600 metres. After being joined by the Seonath, the flows in an easterly direction through the remaining part of its journey. It is joined by the Jonk and Hasdeo rivers here before entering into Odisha after covering about half of its total length, near the city of Sambalpur, it is dammed by the largest earthen dam in the world, the Hirakud Dam. A composite structure of earth, concrete and masonry, the dam measures 24 kilometres including the Dykes and it spans two hills, the Lamdungri on the left and the Chandili Dunguri on the right.

International Hydrographic Organization
–
The International Hydrographic Organization is the inter-governmental organisation representing hydrography. A principal aim of the IHO is to ensure that the seas, oceans. It does this through the setting of standards, the co-ordination of the endeavours of the worlds national hydrographic offices. The IHO enjoys observer status at the United Nations where it is the competent authority on hydrographic surveying. When referring to hydrography and nautical charting in Conventions and similar Instruments, it is the IHO standards, the IHO was established in 1921 as the International Hydrographic Bureau. The present name was adopted in 1970 as part of a new international Convention on the IHO adopted by the member nations. The former name International Hydrographic Bureau was retained to describe the IHO secretariat until 8 November 2016, there were substantial differences in hydrographic procedures charts, and publications. In 1889, an International Maritime Conference was held at Washington, D. C. similar proposals were made at the sessions of the International Congress of Navigation held at Saint Petersburg in 1908 and the International Maritime Conference held at Saint Petersburg in 1912. In 1919 the hydrographers of Great Britain and France cooperated in taking the steps to convene an international conference of hydrographers. London was selected as the most suitable place for this conference, and on 24 July 1919 and this is still the major purpose of the IHO. As a result of the conference, a permanent organization was formed, the IHB, now the IHO, began its activities in 1921 with 18 nations as members. The Principality of Monaco was selected as the seat of the organization as a result of the offer of Albert I, the IHO develops hydrographic and nautical charting standards. These standards are adopted and used by its 86 member countries and others in their surveys, nautical charts. Much has been done in the field of standardisation since the Bureau was founded, the IHO has encouraged the formation of Regional Hydrographic Commissions. Each RHC coordinates the national surveying and charting activities of countries within each region, the 15 RHCs plus the IHO Hydrographic Commission on Antarctica effectively cover the world. The IHO, in partnership with the Intergovernmental Oceanographic Commission, directs the General Bathymetric Chart of the Oceans programme, in 2010 the IHO introduced a new, contemporary hydrographic geospatial standard for modelling marine data and information, known as S-100. S-100 and any dependent product specifications are underpinned by an on-line registry accessible via the IHO website, S-100 is aligned with the ISO19100 series of geographic standards, thereby making it fully compatible with contemporary geospatial data standards. Because S-100 is based on ISO19100, it can be used by other providers for their maritime-related data

Andaman Islands
–
The Andaman Islands form an archipelago in the Bay of Bengal between India, to the west, and Myanmar, to the north and east. Most are part of the Andaman and Nicobar Islands Union Territory of India, while a number in the north of the archipelago, including the Coco Islands. The Andaman Islands are home to the Sentinelese, who have had no contact with any other people, the name of the Andaman Islands is ancient. A theory that became prevalent in the late 19th century is that it derives from Andoman, a form of Hanuman, another Italian traveller, Niccolò de Conti, mentioned the islands and said that the name means Island of Gold. The Andaman islands have been inhabited for several years, at the very least. The indigenous Andamanese people appear to have lived on the islands in substantial isolation from that time until the 18th century CE, from 800 to 1200 CE, the Tamil Chola dynasty created an empire that eventually extended from southeastern peninsular India to parts of Malaysia. Rajendra Chola I took over the Andaman and Nicobar Islands and maintained them as a naval base to launch a naval expedition against the Srivijaya empire. In 1789, Bengal Presidency established a base and penal colony on Chatham Island in the southeast bay of Great Andaman. The settlement is now known as Port Blair, after two years, the colony was moved to the northeast part of Great Andaman and was named Port Cornwallis after Admiral William Cornwallis. However, there was disease and death in the penal colony. In 1824, Port Cornwallis was the rendezvous of the carrying the army to the First Burmese War. In the 1830s and 1840s, shipwrecked crews who landed on the Andamans were often attacked and killed by the natives, in 1855, the government proposed another settlement on the islands, including a convict establishment, but the Indian Rebellion of 1857 forced a delay in its construction. However, because the rebellion gave the British so many prisoners, it made the new Andaman settlement and prison urgently necessary. Construction began in November 1857 at Port Blair using inmates labour,17 May 1859 was another major day for Andaman. The Battle of Aberdeen was fought between the Great Andamanese Tribe and the British, today, a memorial stands in Andaman Water sports complex as a tribute to the people who lost their life. Fearing foreign invasion and with help from a convict from Cellular Jail, the great Andamanese tribe stormed the British post. Later, it was identified that a convict named Doodnath had changed sides. Today, the tribe has been reduced to some 50 people, the government of Andaman Islands is making efforts to increase the headcount of this tribe

Andaman Sea
–
The sea has been traditionally used for fishery and transportation of goods between the coastal countries and its coral reefs and islands are popular tourist destinations. The fishery and tourist infrastructure was damaged by the 2004 Indian Ocean earthquake. At its southeastern reaches, the Andaman Sea narrows to form the Straits of Malacca, the International Hydrographic Organization defines the limits of the Andaman or Burma Sea as follows, On the Southwest. The Eastern limit of the Bay of Bengal, a line joining Lem Voalan in Siam, and Pedropunt in Sumatra. The average depth of the sea is about 1,000 meters, the northern and eastern parts are shallower than 180 meters due to the silt deposited by the Irrawaddy River. This major river flows into the sea from the north through Myanmar, the western and central areas are 900–3,000 meters deep. Less than 5% of the sea is deeper than 3,000 meters, and in a system of submarine valleys east of the Andaman-Nicobar Ridge, the sea floor is covered with pebbles, gravel and sand. Running in a rough north–south line on the seabed of the Andaman Sea is the boundary between two plates, the Burma Plate and the Sunda Plate. As a result, a basin center was created, which began to form the marginal basin which would become the Andaman Sea. The boundary between two tectonic plates results in high seismic activity in the region. Numerous earthquakes have been recorded, and at least six, in 1797,1833,1861,2004,2005 and 2007, had the magnitude of 8.4 or higher. On December 26,2004, a portion of the boundary between the Burma Plate and the Indo-Australian Plate slipped, causing the 2004 Indian Ocean earthquake. This megathrust earthquake had a magnitude of 9.3, between 1300 and 1600 kilometers of the boundary underwent thrust faulting and shifted by about 20 meters, with the sea floor being uplifted several meters. This rise in the sea floor generated a tsunami with an estimated height of 28 meters that killed approximately 280,000 people along the coast of the Indian Ocean. The initial quake was followed by a series of aftershocks along the arc of the Andaman, the entire event severely damaged the fishing infrastructure. Within the sea, to the east of the main Great Andaman island group, lies Barren Island and this island-volcano is 3 km in diameter and rises 354 meters above the sea level. Its recent activity resumed in 1991 after a period of almost 200 years. It is caused by the subduction of the India Plate beneath the Andaman island arc
