The desilting basins (Desanders) of Diversion dam and Main dam were modelled on a Froudian scale of 1:16. Detailed model studies were carried out for evaluating the performance of desilting basins in trapping the suspended load. The coconut shell powder having low specific gravity, was used to simulate the suspended particles. Coconut shell powder proved to be good alternative in view of the shortage of walnut shell powder. Both desanders were found to be more than 90% efficient in trapping the suspended particle size of more than 0.2 mm. The flushing studies were carried out, to formulate the flushing methodology, and to optimize the quantity of water and time required for flushing.
