Dibang River is a tributary river of the Brahmaputra that flows
through the northeast Indian states of
Arunachal Pradesh and Assam.
3 Hydro projects
The Dibang originates near Keya pass on the Indo-Chinese border in the
Dibang Valley district
Dibang Valley district of Arunachal Pradesh. The drainage basin of the
Arunachal Pradesh covers the districts of Dibang Valley
and Lower Dibang Valley. The
Mishmi Hills lie in the upper course
of the Dibang which enters the plains at Nizamghat. Between Nizamghat
Sadiya the Dibang has a steep river gradient and exhibits braided
channel morphology with its width varying from 4 to 9 kilometres (2 to
6 mi). It often changes its course resulting in flooding and
destruction of cultivable land and forests along its banks. The
Dibang, with a total length of 195 kilometres (121 mi), enters
River Lohit north of the Dibru-Saikhowa sanctuary near the
Assamese town of Sadiya.
The Mathun, Tangon, Dri, Ithun and Emra are the major tributaries of
the Dibang. The Dibang is also joined by a number of tributaries such
as the Airi Pani, Ilu Pani, Imu Pani, Ahi, Ashupani, Epipani and
Deopani rivers during its course. Most of these rivers join it in the
upper course in the hills thus giving it a wide fan shaped catchment
In 2008 Prime Minister
Manmohan Singh laid the foundation stone for a
3000 MW dam as part of the Dibang Multipurpose Project the district of
Lower Dibang Valley. Seventeen other dams with power potential between
20 and 4500 MW have also been proposed for the Dibang. The
proposed Dibang dam, at 288 metres (945 ft), on completion would
be among the largest dams in
India and among the world's tallest
gravity dams has since run into opposition from the
Mishmi people and
the Assamese who live downstream of the project.
