River Embankment Protection using TechRevetment® (fabric form concrete mattress) at Sauraha, Nepal

The project is located near Chitwan National Park, Sauraha, Nepal over East Rapti River, A prestigious and famous tourist destination. At the confluence of East Rapti River and its tributary, the right embankment of east Rapti river is susceptible to erosion. For the development of the area and protecting it from overtopping of flow, the owner had earlier protected the right bank by using gabion mattresses and small submerged spurs. East Rapti river carries a lot of sediment with itself during monsoon season. Due to which river changes its direction frequently. The earlier path of the river is towards the left embankment and its main channel has been shifted towards the right side. The silt has been deposited in the center and formed an island. Hence the velocity has been increased towards the right hand side embankment. Consequently, erosion took place on the right-hand side and spurs have been damaged. After going through the site details, river bank embankment protection using TechRevetment® was proposed by Terre Armée.
