Reduction in Erosion & Flood

Strategies for flood protection, bank protection, and river training have been formulated based on detailed hydrological and hydraulic analysis. An optimal width of 263 meters for the water way has been selected and implemented. Both banks of the river have diaphragm walls built into the riverbed at a depth of more than 10m, and retaining walls which protect low-lying areas from periodic flooding and prevent erosion of the river banks. The Sabarmati has been channelized to a constant width without altering the flood carrying capacity of the river. Now the project can sustain flood levels of 4.75 lac cusecs without spillage into the city.
