Reservoirs are used for the storage water, for the purpose of conservation for later use. The loss of storage is only one deleterious effect of sedimentation in reservoirs. Others are increased flood levels upstream of the reservoir, retrogression of the river bed and water levels downstream of the dam, the effect of sedimentation on the reservoir water quality, etc. Phenomena associated with it – the accumulation and erosion – limits the useful life of a reservoir and safe operation of the dam. So far used to solutions is focused primarily on a separate counter the effect of the erosion below the dam or removal of sediment from the reservoir. The article focuses on methods to protect and maintain the capacity storage of the reservoir, to ensure a steady flow of all or part of the material transported by the river.
