<P> In other languages of the region, the river is known as सिन्धु नद (Sindhu Nad) in Hindi and Nepali, سنڌو (Sindhu) in Sindhi, سندھ (Sindh) in Shahmukhi Punjabi, ਸਿੰਧ ਨਦੀ (Sindh Nadī) in Gurmukhī Punjabi, اباسين (Abāsin lit . "Father of Rivers") in Pashto, نهر السند (Nahar al - Sind) in Arabic, སེང ་ གེ ་ གཙང ་ པོ ། (seng ge gtsang po lit . "Lion River" or Lion Spring) in Tibetan, 印度 (Yìndù) in Chinese, and Nilab in Turki . </P> <P> The Indus River provides key water resources for Pakistan's economy--especially the breadbasket of Punjab province, which accounts for most of the nation's agricultural production, and Sindh . The word Punjab means "land of five rivers" and the five rivers are Jhelum, Chenab, Ravi, Beas and Sutlej, all of which finally flow into the Indus . The Indus also supports many heavy industries and provides the main supply of potable water in Pakistan . </P> <P> 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 and Gangdise Shan (Gang Rinpoche, Mt . Kailas) 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 metres (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 the plains of the Punjab and Sindh, where the flow of the river becomes slow and highly braided . It is joined by the Panjnad at Mithankot . Beyond this confluence, the river, at one time, was named the Satnad River (sat = "seven", nadī = "river"), as the river now carried 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 . </P> <P> The Indus is one of the few rivers in the world to 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 states of Jammu and Kashmir and Himachal Pradesh and Gilgit - Baltistan region of Pakistan . 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 . </P>
