The Kali Gandaki (also known as the Narayani in southern Nepal and the Gandak in India) is one of the major rivers of Nepal and a left bank tributary of the Ganges in India. It is also called Krishna Gandaki in Nepal.[1] In Nepal the river is notable for its deep gorge through the Himalayas and its enormous hydroelectric potential. It has a total catchment area of 46,300 square kilometers (17,900 sq mi), most of it in Nepal.

River course

In Nepal, the river quickly crosses different zones of climate
Here, just 25 kilometres (16 mi) downstream from the place above, it flows through a pine forest

The Kali Gandaki river source is at the border with Tibet at an elevation of 6,268 metres (20,564 ft) at the Nhubine Himal Glacier in the Mustang region of Nepal.[2][3]

The headwaters stream on some maps is named the Chhuama Khola and then, nearing Lo Manthang, the Nhichung Khola or Choro Khola. The Kali Gandaki then flows southwest (with the name of Mustang Khola on old maps) through a sheer-sided, deep canyon before widening at the steel footbridge at Chele, where part of its flow funnels through a rock tunnel, and from this point the now wide river is called the Kali Gandaki on all maps. In Kagbeni a major tributary named Johng Khola, Kak Khola or Krishnaa descends from Muktinath.

The river then flows southward through a steep gorge known as the Kali Gandaki Gorge, or Andha Galchi, between the mountains Dhaulagiri, elevation 8,167 metres (26,795 ft) to the west and Annapurna I, elevation 8,091 metres (26,545 ft) to the east. If one measures the depth of a canyon by the difference between the river height and the heights of the highest peaks on either side, this gorge is the world's deepest. The portion of the river directly between Dhaulagiri and Annapurna I, 7 kilometres (4 mi) downstream from Tukuche), is at an elevation of 2,520 metres (8,270 ft),[4] which is 5,571 metres (18,278 ft) lower than Annapurna I. The river is older than the Himalayas. As tectonic activity forces the mountains higher, the river has cut through the uplift.

South of the gorge, the river is joined by Rahughat Khola at Galeshwor, Myagdi Khola at Beni, Modi Khola near Kushma and Badigaad at Rudrabeni above Ridi Bazaar. The river then turns east to run along the northern edge of the Mahabharat Range. The largest hydroelectricity project in Nepal is located along this stretch of the river. Turning south again and breaking through the Mahabharats, Kali Gandaki is then joined by a major tributary, the Trishuli, at Devighat, then by the East Rapti River draining the Inner Terai valley known as Chitwan. The Gandaki then crosses the outermost foothills of the Himalayas—Sivalik Hills—into the Terai plains of Nepal. From Devighat, the river flows southwest of Gaindakot town. The river later curves back towards the southeast as it enters India where it is called the Gandak.

Below Gaindakot the river is known as the Narayani or Sapt Gandaki (Seven Gandakis), for seven tributaries rising in the Himalaya or further north along the main Ganges-Brahmaputra divide. These are the Kali Gandaki, the Trishuli River, and the five main tributaries of the Trishuli known as the Daraudi, Seti, Madi, Marsyandi and Budhi.

India

The entry point of the river at the Indo–Nepal border is also the confluence called Triveni with rivers Pachnad and Sonha descending from Nepal. Pandai river flows into Bihar (India) from Nepal in the eastern end of the Valmiki Sanctuary and meets Masan. The Gandak flows southeast 300 kilometres (190 mi) across the Gangetic plain of Bihar state through West Champaran, Gopalganj, Saran and Muzaffarpur districts. It joins the Ganges near Patna just downstream of Hajipur at Sonepur (also known as Harihar Kshetra). Its drainage area in India is 7,620 square kilometres (2,940 sq mi).

From its exit from the outermost Siwaliks foothills to the Ganges, the Gandak has built an immense megafan comprising Eastern Uttar Pradesh and North Western Bihar in the Middle Gangetic Plains.[5] The megafan consists of sediments eroded from the rapidly uplifting Himalaya. The river's course over this structure is constantly shifting. It is said that the river has shifted 80 kilometres (50 mi) to the east due to tectonic tilting in the last 5,000 years.

Important towns

Major towns and cities located along or near the banks of the Kali Gandaki are Lo Manthang, Jomsom, Beni, Baglung, Kusma, Ridi, Devghat, Bharatpur, Valmikinagar and Triveni. The river also forms the western border of Chitwan National Park. Along the stretch in Nepal, the river carries heavy amounts of glacial silt, imparting the river a black color. The Kali Gandaki, Marshyandi and Seti Rivers are popular whitewater adventure destinations.

The important towns in the Indian part of the Gandak river are the Valmikinagar(Bhainsalotan)- location of Gandak Barrage, Bagaha, Bettiah (district hqrs & field directorate of Valmiki Tiger Project), Harinagar (Ramnagar), Hajipur (across the Ganges 10 km from Patna) and Sonepur (also Known as Harihar Kshetra), near Patna.
