Abstract: A watershed provides a natural geo-hydrological unit for planning any developmental initiative. The approach would be treatment from ?ridge to valley?. The present study has made on the observation of Chevella basin to identify the suitable locations and to suggest appropriate RHS. The basin occupied with black soil mixed with calcareous and gravel. Geomorphic units identified are moderately dissected plateau, shallow weathered plateau, shallow valley fill, slightly dissected plateau, pediment and inselberg. 419 locations are marked for the construction of various RHS. Out of this it is suggested to construct 41 percolation tanks, 189 check dams, 35 check walls and four farm ponds, one earthen bund and 149 rock fill dams. It is felt that community participation is essential for the successful implementation of watershed development program.
