(a) the details of rivers in North Eastern Region (NER) showing change of course as revealed by Remote Sensing and other data sources;
(b) the action plan contemplated for de-siltation, dredging and
erosion control of rivers; and
(c) the extent of sandy deposits by rivers of NER and measures
taken to prevent such deposits?
THE MINISTER OF STATE IN THE MINISTRY OF WATER RESOURCES (SHRI JAI PRAKASH NARAYAN YADAV)
(a) The Department of Space on the request of Brahmaputra Board

in North Eastern Region†based on multi date satellite data. Main
stem to the Brahmaputra river and its major tributaries namely
Beki Manas, Puthimari, Pagladia, Jia Bharelii, Jia Dhol and Buri
Dihing are being studied for their dynamic aspects from the multi
date satellite data.

stability of islands in the Brahmaputra river channel in Assam,
using satellite data acquired in 1990, 1998, 2002 was studied.
The study showed that there are 182 stable patches of river
islands with vegetation covering an area of 16,685 hectare and
1,333 sandbars having an extent of 48,403 hectare of area.
Embankments have been constructed along the banks of the
tributaries of Brahmaputra to prevent spilling of flood waters
and deposition of sand and shingles on the agricultural land
during floods.
