The Puna Tsang Chhu is a Sankosh flowing into the Brahmaputra in the Himalayas of Bhutan .

course

The Puna Tsang is created by the union of the Pha Chhu with the Mo Chhu near Punakha . Since these source rivers, which drain a large area of ​​the west and the center of the country between the Chomolhari and the Kula Kangri , are susceptible to glacier runs , flooding often occurs in the area of ​​the central reaches. The rather low and wide valley between Punakha and Wangdue Phodrang is one of the country's agricultural centers. The valley, which narrows south of Wangdue Phodrang, is followed over long distances by the Wangdue-Tsirang road .

The Dang Chhu flows into Wangdue Phodrang; further tributaries flowing from the east are the Ma Chhu and Hara Chhu, which have their source in the Black Mountains . Near the village of Kalikhola , the river crosses the border with the Indian state of Assam , from where it is named Sankosh . The Sankosh forms in parts the border to the western state of West Bengal . North of Tamarhat , the Sankosh joins the Raidak to form Gangadhar .

The system of the Puna Tsang Chhu drains an area of ​​around 10,000 km² and is thus the second most important river system in Bhutan, the average discharge is around 55 m³ / s.
