FLOOD PROTECTION WORKS ON RIGHT BANK OF NARMADA RIVER

Considering the river bank erosion happening constantly in this region and leading to loss of land and property, Maccaferri suggested to go for simple surface protection measures with flexible gabion mattress and provide a scouring apron with mattress to a length of 6m and a key gabion of height 2m, looking into the practical aspects and actual site conditions. An anchor wall of 3.5m height with gabion was suggested at toe portion of the slope to reduce the scouring action at the toe of the river. The entire slope was stabilized by laying mattress over the slope and providing 2m berms at certain intervals for smooth movement of public. At several locations, gabions and mattresses are constructed as staircase to provide accessibility to river. Benefits: • Gabion and mattress with Zinc + PVC coating were used to provide long term durability and make it more flexible to the impact. • The PVC coated mesh ensures that the strength is not compromised by chemical, biological or environmental degradation. • Gabion and mattress can prevent the surface erosion and the scour action. • They are self draining. So the huge pore pressure that may get developed in the riverfront will get dissipated.
