Siang River

India is planning to build a large barrage on the Siang River to protect it from a Chinese dam being built in Tibet. The dam is being built on the Yarlung Tsangpo River in Tibet’s Medog district.

Arunachal Pradesh Chief Minister Pema Khandu warned that if India does not respond to the dam, his state and neighbouring Assam could face environmental disasters, including floods.

 

What is a barrage? 

A barrage is a dam or barrier built across a river or watercourse to control the flow of water. It typically consists of gates or sluices that can be opened or closed to manage the flow of water downstream.

Barrages are primarily used for flow control and water diversion, while Dams are designed for water storage and regulation on a larger scale.

Yarlung Tsangpo River (Brahmaputra) breaks through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and enters into Arunachal Pradesh, where it is known as Dihang or Siang.
