DIBRUGARH, July 9: Advanced geo-mega tube technology has been employed for the restoration works of a breached embankment in Tengakhat from Monday.
These large bags, filled with sand or slurry, are being used for the first time in dam protection work during floods. Geotextile tubes, or geo tubes, are engineered tube-like sacks made from high-strength woven or non-woven geotextile fabric, typically composed of polypropylene or polyester materials that can withstand the forces of wind, waves, and storms. They 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, began the restoration work of the embankment with a prayer ceremony on Monday, following chief minister Himanta Biswa Sarma’s announcement for immediate restoration work in the Tengakhat area of Dibrugarh.
On July 2, the Tengakhat embankment was breached due to the rising waters of the Buridehing River, submerging more than 25 villages in the Tengakhat revenue circle. On July 5, chief minister Himanta Biswa Sarma visited the breached embankment at Tengakhat and announced that restoration work would begin shortly. Consequently, the Water Resources Department has started the restoration work on a war footing from Monday.
Talking to media persons, Samiran Deka, additional chief engineer of the Water Resources Department’s Upper Assam Zone, said that the restoration work at Tengakhat is being carried out using advanced geo-mega tube technology. “If the weather remains favourable, the work is expected to be completed within 20 days,” Deka said.
Dibrugarh district was affected in the second wave of floods, with most areas coming under water and the streets of Dibrugarh town remaining waterlogged for nine consecutive days. The water has started to recede, but in some areas, people are taking shelter in temporary relief camps near NH-37 in Moran.
