摘要：The article analysis the factors influencing the reduction of reservoir useful volume, including the formation of shores, and proposes and method of their quantitative calculation. The research was provided in the South Surkhandarya reservoir. During the exploitation of the reservoir, were assessed the morphometric index of the basin and changes in a bank due to various influences. The article presented mathematical, statistical calculations of changes in erosion conditions due to displacement of the left banks of the South Surkhandarya Reservoir and changes in pressure in the strata and water saturation of the coastal layers. The proposed method of assessment and calculation will allow development measures to improve the operation of reservoirs based on the determination of morphometric parameters and prevent the formation of shores.
