Abstract: Water resources projects are planned in hilly terrains, where unfavorable geological and topographical conditions prevail. Though hill slopes may be stable under natural conditions, when the slopes are cut for water resources projects, certain elements of instability are induced in the slopes. A systematic evaluation of the slope may be required to design a stable cut slope and to adopt adequate protection measures. If these procedures are not followed, it may lead to unstable conditions hence endangering the safety of the project. Impounding water. behind a dam changes the existing geo-environmental conditions of the area due to water seeping into and the hydrostatic pressures induced into the surrounding: slopes. Moreover, the drawdown conditions of reservoir also changes the stability conditions of the slopes. The geotechnical investigations of reservoirs should incorporate the stability studies of the rim of the reservoir. Hill canals are generally, used for irrigation, power channels and water supply for local uses. Often , the canals for irrigation and water supply are unlined and as such, much of water seeps through the slopes, causing the shear strength of the slope material to reduce, but increasing the overall weight. This is a very favorable condition for landslides to occur. Only systematic evaluation of the slope condition can bring out the nature of instability. The control measures for landslides is dependent on such studies. The control measures generally include four broad categories, namely, a) Reducing the load or flattening of the slopes, b) Loading the toe, c) Increasing the shear strength of the slope material, and d) Providing-effective drainage.
