North Lakhimpur, Assam, India | Water Resource Department, Assam
The river Brahmaputra has been the lifeline of northeastern Indian states for ages. This mighty river runs for 2880 km through China, India, and Bangladesh. Every year the Northeastern state of Assam experiences huge losses due to devastating floods caused by the river Brahmaputra. Some northern plains of Assam like Dhemaji, North Lakhimpur, Dhakuakhana and a few places of Barak Valley experience significant damage due to floods in the Brahmaputra Basin very frequently.
The high intensity of floods in the Brahmaputra River and the steep topography of the region makes the problem more complex and severe. To provide a safeguard against the frequent floods in the region, the banks of the river Brahmaputra near Lakhimpur were required to be protected at a few stretches while providing sustainable anti-erosion measures.
We, at TechFab India, suggested using TechRock™ GeoMattress (A Uniform Tubular Green Mattress) filled with sand (100mm post filling) on the river bank side slope. The work was carried out on the left bank of the Brahmaputra River for a total length of 700m (Approx.) where the river bank was dressed to a slope inclination of 2H:1V for the maximum protected bank height of 12.0m.
The solution implemented using TechFab’s TechRock™ GeoMattress protected the river bank thereby protecting the environment & sustainability of the communities at Dhemaji, Dhakuakhana of Assam.
