Disaster looms large as Siang swells, China warns

River Tsangpo takes the name of river Siang when it enters Arunachal Pradesh and eventually marge with several rivers to be the mighty river Brahmaputra.

The Tsangpo river originates from China and is called Siang once it enters India through Upper Siang district, which then joins two other rivers, Lohit and Dibang, to form the Brahmaputra.

Due to heavy flood and unusual high tides in the Siang River, large scale soil erosion is taking place in the left bank side of Siang River toward Lower Mebo under Mebo Sub-Division, Pasighat in East Siang district.
