Pakistan
–
Pakistan, officially the Islamic Republic of Pakistan, is a federal parliamentary republic in South Asia on the crossroads of Central Asia and Western Asia. It is the sixth-most populous country with a population exceeding 200 million people, in terms of area, it is the 33rd-largest country in the world with an area covering 881,913 square kilometres. It is separated from Tajikistan by Afghanistans narrow Wakhan Corridor in the north, Pakistan is unique among Muslim countries in that it is the only country to have been created in the name of Islam. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and it is an ethnically and linguistically diverse country, with a similarly diverse geography and wildlife. Initially a dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic, an ethnic civil war in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh. The new constitution stipulated that all laws were to conform to the injunctions of Islam as laid down in the Quran. Pakistan has an economy with a well-integrated agriculture sector. The Pakistani economy is the 24th-largest in the world in terms of purchasing power and it is ranked among the emerging and growth-leading economies of the world, and is backed by one of the worlds largest and fastest-growing middle classes. The post-independence history of Pakistan has been characterised by periods of military rule, the country continues to face challenging problems such as illiteracy, healthcare, and corruption, but has substantially reduced poverty and terrorism and expanded per capita income. It is also a member of CERN. Pakistan is a signatory to the Kyoto Protocol, the Paris Agreement, the name Pakistan literally means land of the pure in Urdu and Persian. It is a play on the word pāk meaning pure in Persian and Pashto, the letter i was incorporated to ease pronunciation and form the linguistically correct and meaningful name. Some of the earliest ancient human civilisations in South Asia originated from areas encompassing present-day Pakistan, the earliest known inhabitants in the region were Soanian during the Lower Paleolithic, of whom stone tools have been found in the Soan Valley of Punjab. The Vedic Civilization, characterised by Indo-Aryan culture, laid the foundations of Hinduism, Multan was an important Hindu pilgrimage centre. The Vedic civilisation flourished in the ancient Gandhāran city of Takṣaśilā, the Indo-Greek Kingdom founded by Demetrius of Bactria included Gandhara and Punjab and reached its greatest extent under Menander, prospering the Greco-Buddhist culture in the region. Taxila had one of the earliest universities and centres of education in the world. At its zenith, the Rai Dynasty of Sindh ruled this region, the Pala Dynasty was the last Buddhist empire, which, under Dharampala and Devapala, stretched across South Asia from what is now Bangladesh through Northern India to Pakistan. The Arab conqueror Muhammad bin Qasim conquered the Indus valley from Sindh to Multan in southern Punjab in 711 AD, the Pakistan governments official chronology identifies this as the time when the foundation of Pakistan was laid

India
–
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

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

Yamuna
–
It is the longest river in India which does not directly flow to the sea. Most importantly it creates the highly fertile alluvial, Yamuna-Ganges Doab region between itself and the Ganges in the Indo-Gangetic plain, nearly 57 million people depend on the Yamuna waters. With an annual flow of about 10,000 cubic billion metres and usage of 4,400 cbm, just like the Ganges, the Yamuna too is highly venerated in Hinduism and worshipped as goddess Yamuna, throughout its course. One official describes the river as a drain with biochemical oxygen demand values ranging from 14 to 28 mg/l. Yamunotri temple, a dedicated to the goddess, Yamuna is one of the holiest shrines in Hinduism. Also standing close to the temple, on its 13-kilometre trek route, that follows the bank of the river, lies the Markendeya Tirtha. Large terraces formed over a period of time can be seen in the lower course of the river. Kalanag is the highest point of the entire Yamuna basin, other tributaries in the region are the Giri, Rishi Ganga, Kunta, Hanuman Ganga and Bata tributaries, which drain the Upper Catchment Area of the vast Yamuna basin. Thereafter the river descends on to the plains of Doon Valley, the Yamuna also creates natural state borders between the Himachal Pradesh and Uttarakhand states, and further down between the state of Haryana, Delhi and Uttar Pradesh. The plain itself supports one-third of Indias population through its farming, here pilgrims travel by boats to platforms erected mid stream to offer prayers. During the Kumbh Mela, held every 12 years, the ghats around the Sangam are venue of large congregation of people, the cities of Baghpat, Delhi, Noida, Mathura, Agra, Firozabad, Etawah, Kalpi, Hamirpur, Allahabad lie on its banks. At Etawah, it meets it another important tributary, Chambal, followed by a host of tributaries further down, including, Sindh, the Betwa, and Ken. Tons River, Yamunas largest tributary, rises in the 20,720 ft high Bandarpoonch mountain and it meets Yamuna below Kalsi near Dehradun, Uttarakhand. Sasur Khaderi River, known as Sasur Khaderi is a tributary in Fatehpur district, the name Yamuna seems to be derived from the Sanskrit word yama, meaning twin, and it may have been applied to the river because it runs parallel to the Ganges. The Yamuna is mentioned at many places in the Rig Veda, 1700–1100 BC, and also in the later Atharvaveda, and the Brahmanas including Aitareya Brahmana and Shatapatha Brahmana. In Rig Veda, the story of the Yamuna describes her love for her twin, Yama, who in turn asks her to find a suitable match for herself. It is also said that lord shiva was the reason for the colour of the Yamuna river. After the death of Sati Devi, lord shiva couldnt tolerate the sadness around him, and At last when he went to Yamuna river, it became so black as it absorbed all his sorrow

Floodplain
–
In other words, a floodplain is an area near a river or a stream which floods when the water level reaches flood stage. Flood plains are made by a meander eroding sideways as it travels downstream, when a river breaks its banks and floods, it leaves behind layers of alluvium. These gradually build up to create the floor of the flood plain, floodplains generally contain unconsolidated sediments, often extending below the bed of the stream. These are accumulations of sand, gravel, loam, silt, and/or clay, and are often important aquifers, geologically ancient floodplains are often represented in the landscape by fluvial terraces. These are old floodplains that remain relatively high above the present floodplain and it is probable that any section of such an alluvial plain would show deposits of a similar character. The floodplain during its formation is marked by meandering or anastomotic streams, oxbow lakes and bayous, marshes or stagnant pools, and is occasionally completely covered with water. When the drainage system has ceased to act or is diverted for any reason. The floodplain differs, however, because it is not altogether flat and it has a gentle slope downstream, and often, for a distance, from the side towards the center. The floodplain is the place for a river to dissipate its energy. Meanders form over the floodplain to slow down the flow of water, in terms of flood management the upper part of the floodplain is crucial as this is where the flood water control starts. Artificial canalisation of the river here will have a impact on wider flooding. This is the basis of flood management. Floodplains can support particularly rich ecosystems, both in quantity and diversity, tugay forests form an ecosystem associated with floodplains, especially in Central Asia. They are a category of riparian zones or systems, a floodplain can contain 100 or even 1,000 times as many species as a river. Microscopic organisms thrive and larger species enter a rapid breeding cycle, opportunistic feeders move in to take advantage. The production of nutrients peaks and falls away quickly, however the surge of new growth endures for some time and this makes floodplains particularly valuable for agriculture. River flow rates are undergoing change following suit with climate change and this change is a threat to the riparian zones and other flood plain forests. These forests have over time synced their seedling deposits after the peaks in flow to best take advantage of the nutrient rich soil generated by peak flow

Prairie
–
Temperate grassland regions include the Pampas of Argentina, southern Brazil and Uruguay as well as the steppes of Eurasia. Lands typically referred to as prairie tend to be in North America, the Central Valley of California is also a prairie. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, Prairie is the French word for meadow, but the ultimate root is the Latin pratum. The formation of the North American Prairies started with the upwelling of the Rocky Mountains near Alberta, the mountains created a rain shadow that resulted in lower precipitation rates downwind, creating an environment in which most tree species will not tolerate. The parent material of most prairie soil was distributed during the last glacial advance that began about 110,000 years ago, the glaciers expanding southward scraped the landscape, picking up geologic material and leveling the terrain. As the glaciers retreated about 10,000 years ago, it deposited this material in the form of till, wind based loess deposits also form an important parent material for prairie soils. Tallgrass Prairie evolved over tens of thousands of years with the disturbances of grazing, native ungulates such as bison, elk, and white-tailed deer, roamed the expansive, diverse, plentiful grassland before European colonization of the Americas. For 10, 000-20,000 years native people used fire annually as a tool to assist in hunting, transportation, evidence of ignition sources of fire in the tallgrass prairie are overwhelmingly human as opposed to lightning. Humans, and grazing animals, were participants in the process of prairie formation. Fire has the effect on prairies of removing trees, clearing dead plant matter, fire kills the vascular tissue of trees, but not prairie, as up to 75% of the total plant biomass is below the soil surface and will re-grow from its deep roots. Without disturbance, trees will encroach on a grassland, cast shade, Prairie and widely spaced oak trees evolved to coexist in the oak savanna ecosystem. In spite of long recurrent droughts and occasional torrential rains, the grasslands of the Great Plains were not subject to soil erosion. The root systems of native prairie grasses firmly held the soil in place to prevent run-off of soil, when the plant died, the fungi, bacteria returned its nutrients to the soil. These deep roots also helped native prairie plants reach water in even the driest conditions, the native grasses suffered much less damage from dry conditions than the farm crops currently grown. Prairie in North America is usually split into three groups, wet, mesic, and dry and they are generally characterized by tallgrass prairie, mixed, or shortgrass prairie, depending on the quality of soil and rainfall. In wet prairies the soil is very moist, including during most of the growing season. The resulting stagnant water is conducive to the formation of bogs, wet prairies have excellent farming soil. The average precipitation amount is 10-30 inches a year, mesic prairie /ˈmiːzɪk/ has good drainage, but good soil during the growing season

Ghaggar-Hakra River
–
The Ghaggar-Hakra River is an intermittent, endorheic river in India and Pakistan that flows only during the monsoon season. The river is known as Ghaggar before the Ottu barrage and as the Hakra downstream of the barrage. The basin is classified in two parts, Khadir and Bangar, the area that is not flooded in rainy season is called Bangar. Nineteenth and early 20th century scholars, but also more recent authors, have suggested that the Ghaggar-Hakra might be the remains of the mythological Sarasvati of the Rig Veda. Recent geophysical research does not support this idea and it shows that the Ghaggar-Hakra system was not sourced by the glaciers and snows of the Himalayas, but rather by a system of perennial monsoon-fed rivers. Late Holocene aridification subsequently reduced the Ghaggar-Hakra to the river it is today. The Ghaggar is an intermittent river in India, flowing during the monsoon rains, dammed at Ottu barrage near Sirsa, Ghaggar feeds two irrigation canals that extend into Rajasthan. The main tributaries of the Ghaggar are the Kaushalya river, Markanda, Sarsuti, Tangri, the present-day Sarsuti river originates in a submontane region in the Ambala district and joins the Ghaggar near Shatrana in Punjab. A dried out channel of the Sutlej known as the Naiwal channel joins it near Sadulgarh, finally, near Suratgarh, the Ghaggar is joined by the dried up Chautang river. The Hakra is the channel of a river near Fort Abbas City in Pakistan that is the continuation of the Ghaggar River in India. Several times, but not continuously, it carried the water of the Sutlej, many settlements of the Indus Valley Civilisation have been found along and inside the river beds of the Ghaggar and Hakra rivers. Hakra or Hakro Darya streamed through Sindh and its sign can be found in Sindh areas such as Khairpur, Nawabshah, along the course of the Ghaggar-Hakra river are many archaeological sites of the Indus Valley Civilization, but not further south than the middle of Bahawalpur district. It has been assumed that the Sarasvati ended there in a series of terminal lakes, however, satellite images contradict this, they do not show subterranean water in reservoirs in the dunes between the Indus and the end of the Hakra west of Fort Derawar/Marot. The terrain of this river contains pebbles of quartzite and metamorphic rocks, the Sutlej moved westward and became a tributary of the Indus River while the Yamuna moved eastward and became a tributary of the Ganges. The Sutlej shifted its channel northwards repeatedly, and was captured by the Indus system. The water loss due to these movements caused the Sarasvati river to dry up in the Thar Desert. The date should therefore be pushed back to c 3800 BC. R. Mughal, summing up the evidence, concludes that the Bronze Age Ghaggar-Hakra sometimes carried more, the latter point agrees with a recent isotope study. Painted Grey Ware sites have found in the river bed and not on the banks of the Ghaggar-Hakra river

Canal
–
Canals and navigations are human-made channels for water conveyance, or to service water transport vehicles. In the vernacular, both are referred to as canals, and in most cases, the works will have a series of dams. These areas are referred to as water levels, often just called levels. In contrast, a canal cuts across a drainage divide atop a ridge, many canals have been built at elevations towering over valleys and others water ways crossing far below. Cities need a lot of water and many canals with sources of water at a higher level can deliver water to a destination where there is a lack of water. The Roman Empires Aqueducts were such water supply canals, a navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river, a vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal is a channel that cuts across a drainage divide, most commercially important canals of the first half of the 19th century were a little of each, using rivers in long stretches, and divide crossing canals in others. This is true for many canals still in use, there are two broad types of canal, Waterways, canals and navigations used for carrying vessels transporting goods and people. These can be subdivided into two kinds, Those connecting existing lakes, rivers, other canals or seas and oceans and those connected in a city network, such as the Canal Grande and others of Venice Italy, the gracht of Amsterdam, and the waterways of Bangkok. Aqueducts, water canals that are used for the conveyance and delivery of potable water for human consumption, municipal uses, hydro power canals. Historically canals were of importance to commerce and the development, growth. In 1855 the Lehigh Canal carried over 1.2 million tons of burning anthracite coal, by the 1930s the company which built. By the early 1880s, canals which had little ability to compete with rail transport, were off the map. In the next couple of decades, coal was diminished as the heating fuel of choice by oil. Later, after World War I when motor-trucks came into their own, Canals are built in one of three ways, or a combination of the three, depending on available water and available path, Human made streams A canal can be created where no stream presently exists. Either the body of the canal is dug or the sides of the canal are created by making dykes or levees by piling dirt, stone, the water for the canal must be provided from an external source, like streams or reservoirs. Where the new waterway must change elevation engineering works like locks, lifts or elevators are constructed to raise, examples include canals that connect valleys over a higher body of land, like Canal du Midi, Canal de Briare and the Panama Canal

Allahabad
–
Allahabad, also known as Prayag is a city in the Indian state of Uttar Pradesh and the administrative headquarters of Allahabad District, the most populous district in the state. The city is the capital of Uttar Pradesh with Allahabad High Court being the highest judicial body in the state. In 2011 it was ranked the worlds 130th fastest-growing city, Allahabad, in 2013, was ranked the third most liveable city in the state and twenty-ninth in the country. The citys original name – Prayag, or place of offerings – comes from its position at the Sangam of the Ganga, Yamuna and it is the second-oldest city in India, and plays a central role in Hindu scriptures. Allahabad was originally called Kaushambi by the Kuru rulers of Hastinapur, since then, Allahabad has been a political, cultural and administrative centre of the Doab region. Mughal emperor Akbar renamed it Ilahabad, which the British changed to Allahabad, in 1833 it became the seat of the Ceded and Conquered Provinces region before its capital was moved to Agra in 1835. Allahabad became the capital of the North-Western Provinces in 1858, and was the capital of India for a day, the city was the capital of the United Provinces from 1902 to 1920 and remained at the forefront of national importance during the struggle for Indian independence. Located in southern Uttar Pradesh, the metropolitan area covers 70.5 km2. Although the city and its area are governed by several municipalities. The city is home to colleges, research institutions and central, Allahabad has hosted cultural and sporting events, including Kumbh Mela and the Indira Marathon. Although the citys economy was built on tourism, most of its income now derives from real estate, the city was earlier known as Prayāga, a name still commonly used. Prayāga existed during the Vedic period, and is mentioned in the Veda as the location where Brahma attended a ritual sacrifice, excavations have revealed Northern Black Polished Ware dating to 600–700 BCE. The Puranas record that Yayati left Prayaga and conquered the region of Saptha Sindhu and his five sons founded the main tribes of the Rigveda. Lord Rama, the protagonist of the Ramayana, spent time at the Ashram of Sage Bharadwaj before travelling to nearby Chitrakoot, when the Aryans first settled in what they called the Āryāvarta, Allahabad was an important part of their territory. The Kurus, rulers of Hastinapur, established the town of Kaushambi near Allahabad and they shifted their capital to Kaushambi when Hastinapur was destroyed by floods. The Doab region, which includes Allahabad, was controlled by a succession of empires and dynasties, the area became part of the Mauryan and Gupta Empires from the east and the Kushan Empire from the west before being governed by Kannauj during the 15th century. The city was the site of Maratha incursions before India was colonised, Allahabad became a part of the Delhi Sultanate when it was annexed by Mohammad Ghori in 1193. Later, the Mughals took over from the rulers of Delhi

Vedic period
–
The Vedic period was the period in Indian history during which the Vedas, the oldest scriptures of Hinduism, were composed. During the early part of the Vedic period, the Indo-Aryans settled into northern India, scholars consider Vedic civilisation to have been a composite of the Indo-Aryan and Harappan cultures. The end of the Vedic period witnessed the rise of large, around the beginning of the Common Era, the Vedic tradition formed one of the main constituents of the so-called Hindu synthesis. The commonly proposed period of earlier Vedic age is dated back to 2nd millennium BCE, after the collapse of the Indus Valley Civilisation, which ended c.1900 BCE, groups of Indo-Aryan peoples migrated into north-western India and started to inhabit the northern Indus Valley. The knowledge about the Aryans comes mostly from the Rigveda-samhita, which was composed between c and they brought with them their distinctive religious traditions and practices. The Vedic beliefs and practices of the era were closely related to the hypothesised Proto-Indo-European religion. According to Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the zone between the Zeravshan River and Iran. It was a mixture of old Central Asian and new Indo-European elements. At least 383 non-Indo-European words were borrowed from this culture, including the god Indra, Indra was the subject of 250 hymns, a quarter of the Rig Veda. He was associated more than any other deity with Soma, a stimulant drug probably borrowed from the BMAC religion and his rise to prominence was a peculiar trait of the Old Indic speakers. These migrations may have been accompanied with violent clashes with the people who inhabited this region. The Rig Veda contains accounts of conflicts between the Aryas and the Dasas and Dasyus, the Rig Veda describes Dasas and Dasyus as people who do not perform sacrifices or obey the commandments of gods. Their speech is described as mridhra which could variously mean soft, uncouth, hostile, other adjectives which describe their physical appearance are subject to many interpretations. Internecine military conflicts between the tribes of Vedic Aryans are also described in the Rig Veda. Most notable of such conflicts was the Battle of Ten Kings, which took place on the banks of the river Parushni. The battle was fought between the tribe Bharatas, led by their chief Sudas, against a confederation of ten tribes— Puru, Yadu, Turvasha, Anu, Druhyu, Alina, Bhalanas, Paktha, Siva, Vishanin. Bharatas lived around the regions of the river Saraswati, while Purus, their western neighbours. The other tribes dwelt north-west of the Bharatas in the region of Punjab, division of the waters of Ravi could have been a reason for the war
