The Indus River (Sanskrit: सिन्धु Sindhu; Urdu: دریائے سندھ Daryā-e Sindh; Hindi: सिन्धु नदी Sindhu; Sindhi: سنڌو Sindhu; Punjabi: سندھ Sindh; Gujarati: સિંધુ નદી Sindhu; Pashto: اباسين Abāsin "Father of Rivers"; Persian: رود سند Rūd-e Sind; Arabic: السند Al-Sind; Tibetan: སེང་གེ།་གཙང་པོ Sênggê Zangbo "Lion River"; Greek: Ινδός Indós; Turki: Nilab) is a major river which flows through Pakistan. It has courses through western Tibet (in China) and Northern India.
Originating in the Tibetan plateau in the vicinity of Lake Mansarovar, the river runs a course through the Ladakh region of Jammu and Kashmir, Gilgit, Baltistan and flows through Pakistan in a southerly direction along the entire length of Pakistan to merge into the Arabian Sea near the port city of Karachi in Sindh. The total length of the river is 3,180 km (1,980 mi). It is Pakistan's longest river.
The river has a total drainage area exceeding 1,165,000 km2 (450,000 sq mi). Its estimated annual flow stands at around 207 km3 (50 cu mi), making it the twenty-first largest river in the world in terms of annual flow. Zanskar is its left bank tributary in Ladakh. In the plains, its left bank tributary is Chenab which itself has four major tributaries, namely, Jhelum, Ravi, Beas and Satluj. Its principal right bank tributaries are Shyok, Gilgit, Kabul, Gomal and Kurram. Beginning at the heights of the world in a spring and fed with glaciers and rivers in the Himalayas, the river supports ecosystems of temperate forests, plains and arid countryside.
The Indus forms the delta of Pakistan mentioned in the Vedic Rig Veda as Sapta Sindhu and the Iranic Zend Avesta as Hapta Hindu (both sets of terms meaning Seven Rivers). The river has been a source of wonder during the Classical Period. King Darius of Persia sent Scylax of Caryanda to explore the river in 510 BCE.
The Sanskrit word Sindhu means river, stream or ocean, probably from a root sidh meaning to keep off. Sindhu is still the local appellation for the Indus River.
In the Rigveda Sindhu is the name of the Indus river. Sindhu is attested 176 times in the Rigveda, 95 times in the plural, more often used in the generic meaning. In the Rigveda, notably in the later hymns, the meaning of the word is narrowed to refer to the Indus river in particular, for example in the list of rivers of the Nadistuti sukta. This resulted in the anomaly of a river with masculine gender: all other Rigvedic rivers are female, not just grammatically, being imagined as goddesses and compared to cows and mares yielding milk and butter.
The word Sindhu became Hindu in Old Persian. Ancient Greek: Ἰνδός Indós (borrowed in turn into Latin as Indus) is a borrowing of the Old Iranian word. The name Indos is used in Megasthenes's book Indica for the mighty river crossed by Alexander based on Nearchus's contemporaneous account.
The ancient Greeks referred to the Indians (present-day India beyond the Indus River) as Indoi (Ινδοί), the people of the Indus.
The Indus River provides key water resources for the economy of Pakistan - especially the Breadbasket of Punjab province, which accounts for most of the nation's agricultural production, and Sindh. The word Punjab means "water of five rivers" and the five rivers are Jhelum, Chenab, Ravi, Beas and Sutlej, all of which finally merge in Indus. Indus river also supports many heavy industries and provides the main supply of potable water in Pakistan.
The ultimate source of the Indus is in Tibet; it begins at the confluence of the Sengge and Gar rivers that drain the Nganglong Kangri and Gangdise Shan mountain ranges. 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. It gradually bends to the south, coming out of the hills between Peshawar and Rawalpindi. The Indus passes gigantic gorges 4,500-5,200 m (15,000-17,000 feet) deep near the Nanga Parbat massif. It flows swiftly across Hazara and is dammed at the Tarbela Reservoir. The Kabul river joins it near Attock. The remainder of its route to the sea is in plains of the Punjab and Sindh and the flow of the river becomes slow and highly braided. It is joined by Panjnad River at Mithankot. Beyond this confluence, the river, at one time, was named Satnad River (Sat = seven, Nadi = river), as the river was now carrying the waters of the Kabul River, the Indus River and the five Punjab rivers. Passing by Jamshoro, it ends in a large delta to the east of Thatta.
The Indus is one of the few rivers in the world that exhibit a tidal bore. The Indus system is largely fed by the snows and glaciers of the Himalayas, Karakoram and the Hindu Kush ranges of Tibet, the Indian state of Jammu and Kashmir and the Northern Areas of Pakistan respectively. The flow of the river is also determined by the seasons - it diminishes greatly in the winter, while flooding its banks in the monsoon months from July to September. There is also evidence of a steady shift in the course of the river since prehistoric times - it deviated westwards from flowing into the Rann of Kutch and adjoining Banni grasslands after the 1816 earthquake.[3][4]
The traditional source of the river is the Senge Khabab or 'Lion's Mouth', a perennial spring, not far from the sacred Mount Kailash, and is marked by a long low line of Tibetan chortens. There are several other tributaries nearby which may possibly form a longer stream than Senge Khabab, but unlike the Senger Khabab, are all dependent on snowmelt. The Zanskar River which flows into the Indus in Ladakh has a greater volume of water than the Indus itself before that point.[5]
- "That night in the tent [next to Senge Khabab] I ask Sonmatering which of the Indus tributaries which we crossed this morning is the longest. All of them, he says, start at least a day's walk away from here. The Bukhar begins near the village of Yagra. The Lamolasay's source is in a holy place: there is a monastery there. The Dorjungla is a very difficult and long walk, three days perhaps, and there are many sharp rocks; but it its water is clear and blue, hence the tributary's other name, Zom-chu, which Karma Lama translates as 'Blue Water'. The Rakmajang rises from a dark lake called the Black Sea.
- One of the longest tributaries — and thus a candidate for the river's technical source — is the Kla-chu, the river we crossed yesterday by bridge. Also known as the Lungdep Chu, it flows into the Indus from the south-east, and rises a day's walk from Darchen. But Sonamtering insists that the Dorjungla is the longest of the 'three types of water' that fall into the Seng Tsanplo ['Lion River' or Indus]."[5]
Paleolithic sites have been discovered in Pothohar near Pakistan's capital Islamabad, with the stone tools of the Soan Culture. In ancient Gandhara, near Islamabad, evidence of cave dwellers dated 15,000 years ago has been discovered at Mardan.[citation needed]
The major cities of the Indus Valley Civilization, such as Harappa and Mohenjo-daro, date back to around 3300 BC, and represent some of the largest human habitations of the ancient world. The Indus Valley Civilization extended from across Pakistan and northwest India, with an upward reach from east of Jhelum River to Ropar on the upper Sutlej. The coastal settlements extended from Sutkagan Dor at the Pakistan, Iran border to kutch in easternmost Pakistan. There is an Indus site on the Amu Darya at Shortughai in northern Afghanistan, and the Indus site Alamgirpur at the Hindon River is located only 28 km from Delhi. To date, over 1,052 cities and settlements have been found, mainly in the general region of the Ghaggar-Hakra River and its tributaries. Among the settlements were the major urban centers of Harappa and Mohenjo-daro, as well as Lothal, Dholavira, Ganeriwala, and Rakhigarhi. Only 90-96 of the over-800 known Indus Valley sites have been discovered on the Indus and its tributaries. The Sutlej, now a tributary of the Indus, in Harappan times flowed into the Ghaggar-Hakra River, in the watershed of which were more Harappan sites than along the Indus.
Most scholars believe that settlements of Gandhara grave culture of the early Indo-Aryans flourished in Gandhara from 1700 BC to 600 BC, when Mohenjo-daro and Harappa had already been abandoned.
The word "India" is derived from the Indus River. In ancient times, "India" initially referred to the regions along the eastern banks of the Indus river but, by 300 BCE, Greek writers like Megasthenes applied the term to the subcontinent which extends further eastward.[6]
The Indus has formed a natural boundary between the Indian subcontinent and its frontier with the Iranian Plateau, a region which includes Pakistan's Balochistan, Khyber Pakhtunkhwa as well as Afghanistan, Tajikistan and Iran. It has been crossed by the armies of Alexander the Great - His Macedonian forces retreated along the southern course of the river at the end of the Asian campaign after conquering what is now Pakistan and joining it to the Hellenic Empire. The Indus plains have also been under the domination of the Persian empire and the Kushan empire. The Muslim armies of Muhammad bin Qasim, Mahmud of Ghazni, Mohammed Ghori, Tamerlane and Babur also crossed the river to strike into the inner regions of Punjab and further southeast.

The Indus river feeds the Indus submarine fan, which is the second largest sediment body on the Earth at around 5 million cubic kilometres of material eroded from the mountains. Studies of the sediment in the modern river indicate that the Karakoram Mountains in northern Pakistan and India are the single most important source of material, with the Himalayas providing the next largest contribution, mostly via the large rivers of the Punjab (Jhelum, Ravi, Chenab, Beas and Sutlej). Analysis of sediments from the Arabian Sea has demonstrated that prior to five million years ago the Indus was not connected to these Punjab rivers which instead flowed east into the Ganges and were captured after that time.[7] Earlier work showed that sand and silt from western Tibet was reaching the Arabian Sea by 45 million years ago, implying the existence of an ancient Indus River by that time.[8] The delta of this proto-Indus river has subsequently been found in the Katawaz Basin, on the Afghan-Pakistan border.
In the Nanga Parbat region, the massive amounts of erosion due to the Indus river following the capture and rerouting through that area is thought to bring middle and lower crustal rocks to the surface.[9]

Accounts of the Indus valley from the times of Alexander's campaign indicate a healthy forest cover in the region, which has now considerably receded. The Mughal Emperor Babur writes of encountering rhinoceroses along its bank in his memoirs (the Baburnama). Extensive deforestation and human interference in the ecology of the Shivalik Hills has led to a marked deterioration in vegetation and growing conditions. The Indus valley regions are arid with poor vegetation. Agriculture is sustained largely due to irrigation works.
The blind Indus River Dolphin (Platanista gangetica minor) is a sub-species of dolphin found only in the Indus River. It formerly also occurred in the tributaries of the Indus river. According to the World Wildlife Fund claims it is one of the most threatened cetaceans with only about 1000 still existing.[10]
Palla fish (Hilsa) of the river is a delicacy for people living along the river. The population of fishes in the river is moderately high, with Sukkur, Thatta and Kotri being the major fishing centres - all in the lower Sindh course. But damming and irrigation has made fish farming an important economic activity. Located southeast of Karachi, the large delta has been recognised by conservationists as one of the world's most important ecological regions. Here the river turns into many marshes, streams and creeks and meets the sea at shallow levels. Here marine fishes are found in abundance, including pomfret and prawns.
The Indus is the most important supplier of water resources to the Punjab and Sindh plains - it forms the backbone of agriculture and food production in Pakistan. The river is especially critical as rainfall is meagre in the lower Indus valley. Irrigation canals were first built by the people of the Indus valley civilization, and later by the engineers of the Kushan Empire and the Mughal Empire. Modern irrigation was introduced by the British East India Company in 1850 - the construction of modern canals accompanied with the restoration of old canals. The British supervised the construction of one of the most complex irrigation networks in the world. The Guddu Barrage is 1,350 m (4,430 ft) long - irrigating Sukkur, Jacobabad, Larkana and Kalat. The Sukkur Barrage serves over 20,000 km2 (7,700 sq mi).
After Pakistan came into existence, a water control treaty signed between India and Pakistan in 1960 guaranteed that Pakistan would receive water from the Indus River and its two western tributaries, the Jhelum River & the Chenab River independent of upstream control by India.[11] The project, Indus Basin Project, consisted primarily of the construction of two main dams, the Mangala Dam built on the Jhelum River and the Tarbela Dam constructed on the Indus River, together with their subsidiary dams.[12] The Pakistan Water and Power Development Authority undertook the construction of the Chashma-Jhelum link canal - linking the waters of the Indus and Jhelum rivers - extending water supplies to the regions of Bahawalpur and Multan. Pakistan constructed the Tarbela Dam near Rawalpindi - standing 2743 metres (9,000 ft) long and 143 metres (470 ft) high, with an 80-kilometre (50 mi) long reservoir. The Kotri Barrage near Hyderabad is 915 metres (3,000 ft) long and provides additional supplies for Karachi. The Taunsa Barrage near Dera Ghazi Khan produces 100,000 kilowatts of electricity. The extensive linking of tributaries with the Indus has helped spread water resources to the valley of Peshawar, in the Khyber Pakhtunkhwa. The extensive irrigation and dam projects provide the basis for Pakistan's large production of crops such as cotton, sugarcane and wheat. The dams also generate electricity for heavy industries and urban centres.
The inhabitants of the regions through which the Indus river passes and forms a major natural feature and resource are diverse in ethnicity, religion, national and linguistic backgrounds. On the northern course of the river in the state of Jammu and Kashmir in India, live the Buddhist people of Ladakh, of Tibetan stock, and the Dards of Indo-Aryan or Dardic stock and practising Buddhism and Islam. Then it descends into Baltistan, northern Pakistan passing the main Balti city of Skardu. As it continues through Pakistan, the Indus river forms a distinctive boundary of ethnicity and cultures - upon the western banks the population is largely Pashtun, Baloch, and of other Iranic stock, with close cultural, economic and ethnic ties to eastern Afghanistan and parts of Iran. The eastern banks are largely populated by peoples of Indo-Aryan stock, such as the Punjabis and the Sindhis. In northern Punjab and the Khyber Pakhtunkhwa, ethnic Pashtun tribes live alongside Dardic people in the hills (Khowar, Kalash, Shina, etc.), Burushos (in Hunza), and Punjabi people.In the province of Sindh, peoples of Sindhi backgrounds form the local populations. Upon the western banks of the river live the Baloch and Pashtun peoples of Balochistan.

The Indus is a strategically vital resource for Pakistan's economy and society. After India became independent in 1947 and Pakistan came into existence in 1947, the use of the waters of the Indus and its five eastern tributaries became a major dispute between India and Pakistan. The irrigation canals of the Sutlej valley and the Bari Doab were split - with the canals lying primarily in Pakistan and the headwork dams in India disrupting supply in some parts of Pakistan. The concern over India building large dams over various Punjab rivers that could undercut the supply flowing to Pakistan, as well as the possibility that India could divert rivers in the time of war, caused political consternation in Pakistan. Holding diplomatic talks brokered by the World Bank, India and Pakistan signed the Indus Waters Treaty in 1960. The treaty gave India control of the three easternmost rivers of the Punjab, the Sutlej, the Beas and the Ravi, while Pakistan gained control of the three western rivers, the Jhelum, the Chenab and the Indus. India retained the right to use of the western rivers for non-irrigation projects. (See discussion regarding a recent dispute about a hydroelectric project on the Chenab (not Indus) known as the Baglihar Project).
There are concerns that extensive deforestation, industrial pollution and global warming are affecting the vegetation and wildlife of the Indus delta, while affecting agricultural production as well. There are also concerns that the Indus river may be shifting its course westwards - although the progression spans centuries. On numerous occasions, sediment clogging owing to poor maintenance of canals has affected agricultural production and vegetation. In addition, extreme heat has caused water to evaporate, leaving salt deposits that render lands useless for cultivation.
Recently, India's construction of dams on the river, which Pakistan claims is in violation of the Indus Waters Treaty reducing water flow into Pakistan, has caused Pakistan to take the issue to the international courts for arbitration.
The Tibetan Plateau contains the world's third-largest store of ice. Qin Dahe, the former head of the China Meteorological Administration, said the recent fast pace of melting and warmer temperatures will be good for agriculture and tourism in the short term, but issued a strong warning:
"Temperatures are rising four times faster than elsewhere in China, and the Tibetan glaciers are retreating at a higher speed than in any other part of the world... In the short term, this will cause lakes to expand and bring floods and mudflows.. In the long run, the glaciers are vital lifelines of the Indus River. Once they vanish, water supplies in Pakistan will be in peril."[13]
"There is [sic] insufficient data to say what will happen to the Indus," says David Grey, the World Bank's senior water advisor in South Asia. "But we all have very nasty fears that the flows of the Indus could be severely, severely affected by glacier melt as a consequence of climate change," and reduced by perhaps as much as 50 percent. "Now what does that mean to a population that lives in a desert [where], without the river, there would be no life? I don't know the answer to that question," he says. "But we need to be concerned about that. Deeply, deeply concerned."[14]
Affected areas as of August 26, 2010
In July 2010, following abnormally heavy monsoon rains, the Indus River rose above its banks and started flooding. The rain continued for the next two months, devastating large areas of Pakistan. In Sindh, the Indus burst its banks near Sukkur on 8 August, submerging the village of Mor Khan Jatoi.[15] In early August, the heaviest flooding moved southward along the Indus River from severely affected northern regions toward western Punjab, where at least 1,400,000 acres (570,000 ha) of cropland was destroyed, and the southern province of Sindh.[16] As of September 2010[update], over two thousand people have died[17] and over a million homes have been destroyed since the flooding began.[18]
