Assam: Advanced Geo-Mega Tube Technology Deployed for Urgent Restoration of Breached Tengakhat Embankment

These tubes are placed in a trench along the shoreline or riverbank and then covered with more sand or soil to create a natural-looking barrier by blending in with the surrounding landscape.

The Water Resources Department, Dibrugarh on Monday started the restoration work of embankment with a prayer ceremony after Chief Minister Himanta Biswa Sarma announced for immediate restoration work to began in the Tengakhat area of Dibrugarh.
