Ramsar Convention
–
The Ramsar Convention is an international treaty for the conservation and sustainable use of wetlands. It is also known as the Convention on Wetlands and it is named after the city of Ramsar in Iran, where the Convention was signed in 1971. The most recent COP12 was held in Punta del Este, Uruguay, cOP13 will take place in Dubai, United Arab Emirates, in 2018. The List of Wetlands of International Importance included 2,231 Ramsar Sites in March 2016 covering over 2.1 million square kilometres. The country with the highest number of Sites is the United Kingdom with 170, the Ramsar Sites Information Service is a searchable database which provides information on each Ramsar Site. As of 2016 there are 18 Transboundary Ramsar Sites, as of 2016 there are 15 Ramsar Regional Initiatives covering regions of the Mediterranean, Asia, Africa and South America. The Ramsar Convention works closely with six other known as International Organization Partners. The IOPs also participate regularly as observers in all meetings of the Conference of the Parties and as members of the Scientific. Conference of the Parties Conference of the Parties is the Conventions governing body consisting of all governments that have ratified the treaty and this ultimate authority reviews progress under the Convention, identifies new priorities, and sets work plans for members. The COP can also make amendments to the Convention, create expert advisory bodies, review progress reports by member nations, and collaborate with other international organizations and agreements. The Standing Committee The Standing Committee is the executive body which represents the COP between its triennial meetings, within the framework of the decisions made by the COP. The Contracting Parties that are members of the Standing Committee are elected by each meeting of the COP to serve for the three years until the next one, the Secretariat The Secretariat carries out the day-to-day coordination of the Convention’s activities. It is based at the headquarters of the International Union for the Conservation of Nature in Gland, Switzerland, the 2nd of February each year is World Wetlands Day, marking the date of the adoption of the Convention on Wetlands on 2 February 1971. Established to raise awareness about the value of wetlands for humanity, in 2015 World Wetlands Day was celebrated in 59 countries

Gujarat
–
Gujarat is a state in Western India, sometimes referred to as the Jewel of Western India. It has an area of 196,024 km2 with a coastline of 1,600 km, most of which lies on the Kathiawar peninsula, and a population in excess of 60 million. The state is bordered by Rajasthan to the north, Maharashtra to the south, Madhya Pradesh to the east, and the Arabian Sea and its capital city is Gandhinagar, while its largest city is Ahmedabad. Gujarat is home to the Gujarati-speaking people of India, the state encompasses some sites of the ancient Indus Valley Civilization, such as Lothal and Dholavira. Lothal is believed to be one of the worlds first seaports, Gujarat was known to the ancient Greeks, and was familiar in other Western centres of civilisation through the end of the European Middle Ages. Modern-day Gujarat is derived from Sanskrit term Gurjaradesa, the Gurjar nation, parts of modern Rajasthan and Gujarat have been known as Gurjaratra or Gurjarabhumi for centuries before the Mughal period. Gujarat was one of the centres of the Indus Valley Civilization. It contains ancient metropolitan cities from the Indus Valley such as Lothal, Dholavira, the ancient city of Lothal was where Indias first port was established. The ancient city of Dholavira is one of the largest and most prominent archaeological sites in India, the most recent discovery was Gola Dhoro. Altogether, about 50 Indus Valley settlement ruins have been discovered in Gujarat, the ancient history of Gujarat was enriched by the commercial activities of its inhabitants. There is clear evidence of trade and commerce ties with Egypt, Bahrain. The early history of Gujarat reflects the grandeur of Chandragupta Maurya who conquered a number of earlier states in what is now Gujarat. Pushyagupta, a Vaishya, was appointed governor of Saurashtra by the Mauryan regime and he ruled Giringer and built a dam on the Sudarshan lake. Between the decline of Mauryan power and Saurashtra coming under the sway of the Samprati Mauryas of Ujjain, in the first half of the 1st century AD there is the story of a merchant of King Gondaphares landing in Gujarat with Apostle Thomas. The incident of the cup-bearer killed by a lion might indicate that the city described is in Gujarat. For nearly 300 years from the start of the 1st century AD, the weather-beaten rock at Junagadh gives a glimpse of the ruler Rudradaman I of the Saka satraps known as Western Satraps, or Kshatraps. Mahakshatrap Rudradaman I founded the Kardamaka dynasty which ruled from Anupa on the banks of the Narmada up to the Aparanta region which bordered Punjab, in Gujarat several battles were fought between the south Indian Satavahana dynasty and the Western Satraps. The greatest ruler of the Satavahana Dynasty was Gautamiputra Satakarni who defeated the Western Satraps, the Kshatrapa dynasty was replaced by the Gupta Empire with the conquest of Gujarat by Chandragupta Vikramaditya

Salt marsh
–
It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the marsh in trapping and binding sediments. Salt marshes play a role in the aquatic food web. They also support terrestrial animals and provide coastal protection, salt marshes occur on low-energy shorelines in temperate and high-latitudes which can be stable or emerging, or submerging if the sedimentation rate exceeds the subsidence rate. Commonly these shorelines consist of mud or sand flats which are nourished with sediment from inflowing rivers and these typically include sheltered environments such as embankments, estuaries and the leeward side of barrier islands and spits. In the tropics and sub-tropics they are replaced by mangroves, an area that differs from a marsh in that instead of herbaceous plants. Most salt marshes have a low topography with low elevations but a vast wide area, salt marshes are located among different landforms based on their physical and geomorphological settings. Such marsh landforms include deltaic marshes, estuarine, back-barrier, open coast, embayments, deltaic marshes are associated with large rivers where many occur in Southern Europe such as the Camargue, France in the Rhone delta or the Ebro delta in Spain. They are also extensive within the rivers of the Mississippi Delta in the United States, in New Zealand, most salt marshes occur at the head of estuaries in areas where there is little wave action and high sedimentation. Such marshes are located in Awhitu Regional Park in Auckland, the Manawatu Estuary, back-barrier marshes are sensitive to the reshaping of barriers in the landward side of which they have been formed. They are common along much of the eastern coast of the United States, large, shallow coastal embayments can hold salt marshes with examples including Morecambe Bay and Portsmouth in Britain and the Bay of Fundy in North America. They have a big impact on the biodiversity of the area, salt marsh ecology involves complex food webs which include primary producers, primary consumers, and secondary consumers. The low physical energy and high grasses provide a refuge for animals, many marine fish use salt marshes as nursery grounds for their young before they move to open waters. Saltmarshes across 99 countries were mapped by Mcowen et al, a total of 5,495,089 hectares of mapped saltmarsh across 43 countries and territories are represented in a Geographic Information Systems polygon shapefile. This estimate is at the low end of previous estimates. Mats of filamentous blue-green algae can fix silt and clay sized sediment particles to their sticky sheaths on contact which can increase the erosion resistance of the sediments. This assists the process of sediment accretion to allow colonising species to grow, as a result, competitive species that prefer higher elevations relative to sea level can inhabit the area and often a succession of plant communities develops. Coastal salt marshes can be distinguished from terrestrial habitats by the tidal flow that occurs

Thar Desert
–
The Thar Desert, also known as the Great Indian Desert, is a large, arid region in the northwestern part of the Indian subcontinent that forms a natural boundary between India and Pakistan. It is the worlds 17th largest desert, and the worlds 9th largest subtropical desert, about 85% of the Thar Desert is in India, and the remaining part in Pakistan. In India, it covers about 320,000 km2, forming approximately 10% of the geographic area of India. More than 60% of the lies in the state of Rajasthan and extends into Gujarat, Punjab. This desert comprises a very dry part, the Marusthali region in the west, the Thar Desert extends between the Aravalli Hills in the north-east, the Great Rann of Kutch along the coast and the alluvial plains of the Indus River in the west and north-west. Most of the desert is covered by shifting sand dunes that receive sediments from the alluvial plains. The sand is highly due to strong winds occurring before the onset of the monsoon. The Luni River is the only integrated into the desert. Rainfall is limited to 100–500 mm per year, mostly falling from July to September, salt water lakes in the Thar Desert include the Sambhar, Kuchaman, Didwana in Rajasthan and Kharaghoda in Gujarat. These lakes receive rain water during monsoon and evaporate during the dry season, the salt is derived by the weathering of rocks in the region. Lithic tools belonging to the prehistoric Aterian culture of the Maghreb have been discovered in Middle Paleolithic deposits in the Thar Desert, the soil of the Thar Desert remains dry for much of the year and is prone to wind erosion. High velocity winds blow soil from the desert, depositing some on neighboring fertile lands, the 649 km long Indira Gandhi Canal brings fresh water to the Thar Desert. It was conceived to halt spreading of the desert to fertile areas, there are few local tree species suitable for planting in the desert, which are slow growing. Therefore, exotic species were introduced for plantation. Many species of Eucalyptus, Acacia, Cassia and other genera from Israel, Australia, US, Russia, Zimbabwe, Chile, Peru and Sudan have been tried in Thar Desert. Acacia tortilis has proved to be the most promising species for desert afforestation, there are several protected areas in the Thar Desert. In India, the Desert National Park covers 3,162 km2 and represents the Thar Desert ecosystem and its diverse fauna includes the great Indian bustard, blackbuck, chinkara, fox, Bengal fox, wolf, and caracal. Seashells and massive fossilized tree trunks in this record the geological history of the desert

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

Mahabharata
–
The Mahābhārata is one of the two major Sanskrit epics of ancient India, the other being the Rāmāyaṇa. The Mahābhārata is a narrative of the Kurukṣetra War and the fates of the Kaurava. It also contains philosophical and devotional material, such as a discussion of the four goals of life or puruṣārtha, traditionally, the authorship of the Mahābhārata is attributed to Vyāsa. There have been attempts to unravel its historical growth and compositional layers. The oldest preserved parts of the text are thought to be not much older than around 400 BCE, the text probably reached its final form by the early Gupta period. The title may be translated as the tale of the Bhārata dynasty. According to the Mahābhārata itself, the tale is extended from a version of 24,000 verses called simply Bhārata. The Mahābhārata is the longest known epic poem and has described as the longest poem ever written. Its longest version consists of over 100,000 śloka or over 200,000 individual verse lines, and long prose passages. About 1.8 million words in total, the Mahābhārata is roughly ten times the length of the Iliad and the Odyssey combined, or about four times the length of the Rāmāyaṇa. W. J. Johnson has compared the importance of the Mahābhārata in the context of civilization to that of the Bible, the works of Shakespeare. The epic is traditionally ascribed to the sage Vyāsa, who is also a character in the epic. Vyāsa described it as being itihāsa and he also describes the Guru-shishya parampara, which traces all great teachers and their students of the Vedic times. The first section of the Mahābhārata states that it was Gaṇeśa who wrote down the text to Vyasas dictation, the epic employs the story within a story structure, otherwise known as frametales, popular in many Indian religious and non-religious works. It is recited by the sage Vaiśampāyana, a disciple of Vyāsa, the text has been described by some early 20th-century western Indologists as unstructured and chaotic. Hermann Oldenberg supposed that the poem must once have carried an immense tragic force. Moritz Winternitz considered that only unpoetical theologists and clumsy scribes could have lumped the parts of disparate origin into an unordered whole, Research on the Mahābhārata has put an enormous effort into recognizing and dating layers within the text. Some elements of the present Mahābhārata can be traced back to Vedic times, the background to the Mahābhārata suggests the origin of the epic occurs after the very early Vedic period and before the first Indian empire was to rise in the third century B. C

Indus River
–
The Indus River, also called Sindhū or Abāsīn, is a major south-flowing river in South Asia. The total length of the river is 3,180 km which makes it one of the longest rivers in Asia and it is the longest river and national river of Pakistan. The river has a drainage area exceeding 1,165,000 km2. Its estimated annual flow stands at around 207 km3, making it the twenty-first largest river in the world in terms of annual flow, the Zanskar is its left bank tributary in Ladakh. In the plains, its left tributary is the Chenab which itself has four major tributaries, namely, the Jhelum, the Ravi, the Beas. Its principal right tributaries are the Shyok, the Gilgit, the Kabul, the Gomal. Beginning in a spring and fed with glaciers and rivers in the Himalayas. The Indus forms the delta of present-day Pakistan mentioned in the Vedic Rigveda as Sapta Sindhu, the river has been a source of wonder since the Classical Period, with King Darius of Persia sending his Greek subject Scylax of Caryanda to explore the river as early as 510 BC. In Pali, Síndhu means river, stream and refers to the Indus River in particular, the word Indus is the romanised form of the ancient Greek word Indós, borrowed from the old Persian word Hinduš which is in turn borrowed from the Sanskrit word Sindhu. Megastheness book Indica derives its name from the rivers Greek name, Indós, the ancient Greeks referred to the Indians as Indói, literally meaning the people of the Indus. The country of India and the Pakistani province of Sindh owe their names to the river, Rigveda also describes several mythical rivers, including one named Sindhu. The Rigvedic Sindhu is thought to be the present-day Indus river and is attested 176 times in its text –95 times in the plural, more often used in the generic meaning. In the Rigveda, notably in the hymns, the meaning of the word is narrowed to refer to the Indus river in particular. The Rigvedic hymns apply a feminine gender to all the rivers mentioned therein, Sindhu is seen as a strong warrior amongst other rivers which are seen as goddesses and compared to cows and mares yielding milk and butter. The Indus River provides key resources for Pakistans economy – especially the breadbasket of Punjab province, which accounts for most of the nations agricultural production. The word Punjab means land of five rivers and the five rivers are Jhelum, Chenab, Ravi, Beas and Sutlej, the Indus also supports many heavy industries and provides the main supply of potable water in Pakistan. The ultimate source of the Indus is in Tibet, the river begins at the confluence of the Sengge Zangbo and Gar Tsangpo rivers that drain the Nganglong Kangri, the Indus then flows northwest through Ladakh and Baltistan into Gilgit, just south of the Karakoram range. The Shyok, Shigar and Gilgit rivers carry glacial waters into the main river and it gradually bends to the south, coming out of the hills between Peshawar and Rawalpindi

Monsoon
–
Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is sometimes used for locally heavy but short-term rains. The major monsoon systems of the world consist of the West African and Asia-Australian monsoons, the inclusion of the North and South American monsoons with incomplete wind reversal has been debated. The south-west monsoon winds are called Nairutya Maarut in India, the English monsoon came from Portuguese monção, ultimately from Arabic mawsim and/or Hindi mausam, perhaps partly via early modern Dutch monsun. Strengthening of the Asian monsoon has been linked to the uplift of the Tibetan Plateau after the collision of the Indian sub-continent and Asia around 50 million years ago. Because of studies of records from the Arabian Sea and that of the wind-blown dust in the Loess Plateau of China, testing of this hypothesis awaits deep ocean sampling by the Integrated Ocean Drilling Program. The monsoon has varied significantly in strength since this time, largely linked to climate change. A study of marine plankton suggested that the Indian Monsoon strengthened around 5 million years ago, then, during ice periods, the sea level fell and the Indonesian Seaway closed. When this happened, cold waters in the Pacific were impeded from flowing into the Indian Ocean and it is believed that the resulting increase in sea surface temperatures in the Indian Ocean increased the intensity of monsoons. Five episodes during the Quaternary at 2.22 Ma,1.83 Ma,0.68 Ma,0.45 Ma and 0.04 Ma were identified which showed a weakening of Leeuwin Current. The weakening of the LC would have an effect on the sea surface temperature field in the Indian Ocean, thus these five intervals could probably be those of considerable lowering of SST in the Indian Ocean and would have influenced Indian monsoon intensity. The impact of monsoon on the weather is different from place to place. In some places there is just a likelihood of having a more or less rain. In other places, quasi semi-deserts are turned into green grasslands where all sorts of plants. The Indian Monsoon turns large parts of India from a kind of semi-desert into green lands, see photos only taken 3 months apart in the Western Ghats. In places like this it is crucial for farmers to have the right timing for putting the seeds on the fields, Monsoons are large-scale sea breezes which occur when the temperature on land is significantly warmer or cooler than the temperature of the ocean. These temperature imbalances happen because oceans and land absorb heat in different ways, in contrast, dirt, sand, and rocks have lower heat capacities, and they can only transmit heat into the earth by conduction and not by convection. Therefore, bodies of water stay at an even temperature

Arabian Sea
–
The Arabian Sea is a region of the northern Indian Ocean bounded on the north by Pakistan and Iran, on the west by northeastern Somalia and the Arabian Peninsula, and on the east by India. Historically the sea has been known by names including the Erythraean Sea. Its total area is 3,862,000 km2 and its depth is 4,652 metres. The Gulf of Aden is in the southwest, connecting the Arabian Sea to the Red Sea through the strait of Bab-el-Mandeb, the Arabian Sea has been crossed by important marine trade routes since the third or second millennium BCE. Major seaports include Jawaharlal Nehru Port in Mumbai, the Port of Karachi and the Gwadar Port in Pakistan, other important ports include in India, Kandla Port, and Mormugao in Goa. The largest islands in the Arabian Sea include Socotra, Masirah Island, Astola Island, the Arabian Seas surface area is about 3,862,000 km2. The maximum width of the Sea is approximately 2,400 km, the biggest river flowing into the Sea is the Indus River. There are also the gulfs of Khambhat and Kutch on the Indian coast, the countries with coastlines on the Arabian Sea are Somalia, Djibouti, Yemen, Oman, United Arab Emirates, Iran, Pakistan, India and the Maldives. There are several cities on the seas coast including Mumbai, Surat, Karachi, Gwadar, Pasni, Ormara, Aden, Muscat, Keti Bandar, Salalah, Duqm. International Hydrographic Organization defines the limits of the Arabian Sea as follows, the Eastern limit of the Gulf of Aden. A line joining Ràs al Hadd, East point of Arabia, a line running from the South extremity of Addu Atoll, to the Eastern extreme of Ràs Hafun. The Western limit of the Laccadive Sea, by the time of Julius Caesar, several well-established combined land-sea trade routes depended upon water transport through the Sea around the rough inland terrain features to its north. Each major route involved transhipping to pack animal caravan, travel through country and risk of bandits. Later the kingdom of Axum arose in Ethiopia to rule a mercantile empire rooted in the trade with Europe via Alexandria, Jawaharlal Nehru Port in Mumbai is the largest port in the Arabian Sea, and the largest container port in India. The Port of Karachi is Pakistans largest and busiest seaport, handling about 60% of the nations cargo and it is located between the Karachi towns of Kiamari and Saddar, close to the main business district and several industrial areas. The geographic position of the places it in close proximity to major shipping routes such as the Strait of Hormuz. The history of the port is intertwined with that of the city of Karachi, several ancient ports have been attributed in the area including Krokola, Morontobara, Barbarikon (the Periplus of the Erythraean Sea, and Debal. It warns sailors about whirlpools and advises them to safety in Kaurashi harbour if they found themselves drifting dangerously

Alexander the Great
–
Alexander III of Macedon, commonly known as Alexander the Great, was a king of the Ancient Greek kingdom of Macedon and a member of the Argead dynasty. He was born in Pella in 356 BC and succeeded his father Philip II to the throne at the age of twenty and he was undefeated in battle and is widely considered one of historys most successful military commanders. During his youth, Alexander was tutored by Aristotle until the age of 16, after Philips assassination in 336 BC, he succeeded his father to the throne and inherited a strong kingdom and an experienced army. Alexander was awarded the generalship of Greece and used this authority to launch his fathers Panhellenic project to lead the Greeks in the conquest of Persia, in 334 BC, he invaded the Achaemenid Empire and began a series of campaigns that lasted ten years. Following the conquest of Anatolia, Alexander broke the power of Persia in a series of battles, most notably the battles of Issus. He subsequently overthrew Persian King Darius III and conquered the Achaemenid Empire in its entirety, at that point, his empire stretched from the Adriatic Sea to the Indus River. He sought to reach the ends of the world and the Great Outer Sea and invaded India in 326 BC and he eventually turned back at the demand of his homesick troops. Alexander died in Babylon in 323 BC, the city that he planned to establish as his capital, without executing a series of planned campaigns that would have begun with an invasion of Arabia. In the years following his death, a series of civil wars tore his empire apart, resulting in the establishment of several states ruled by the Diadochi, Alexanders surviving generals, Alexanders legacy includes the cultural diffusion which his conquests engendered, such as Greco-Buddhism. He founded some twenty cities that bore his name, most notably Alexandria in Egypt, Alexander became legendary as a classical hero in the mold of Achilles, and he features prominently in the history and mythic traditions of both Greek and non-Greek cultures. He became the measure against which military leaders compared themselves, and he is often ranked among the most influential people in human history. He was the son of the king of Macedon, Philip II, and his wife, Olympias. Although Philip had seven or eight wives, Olympias was his wife for some time. Several legends surround Alexanders birth and childhood, sometime after the wedding, Philip is said to have seen himself, in a dream, securing his wifes womb with a seal engraved with a lions image. Plutarch offered a variety of interpretations of dreams, that Olympias was pregnant before her marriage, indicated by the sealing of her womb. On the day Alexander was born, Philip was preparing a siege on the city of Potidea on the peninsula of Chalcidice. That same day, Philip received news that his general Parmenion had defeated the combined Illyrian and Paeonian armies, and it was also said that on this day, the Temple of Artemis in Ephesus, one of the Seven Wonders of the World, burnt down. This led Hegesias of Magnesia to say that it had burnt down because Artemis was away, such legends may have emerged when Alexander was king, and possibly at his own instigation, to show that he was superhuman and destined for greatness from conception

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
