The results of field studies to study the siltation of a reservoir and the dynamics of their siltation are presented. The article presents designs that allow reducing the amount of sediment entering the reservoir bowl. The structure will contain spillways located perpendicular to the bed of the supply channel, elements of connecting structures, a sediment storage facility, and a lateral water outlet to the sediment storage facility. The reservoir sediment has a mark below the bottom of the supply channel and above the maximum water level in the reservoir and a wall of large pebbles that act as a filter for residual turbid water in the channel. In the basin of the deposit storage, a road is provided for trucks and equipment to carry out its seasonal cleaning.

A comprehensive study of the flow of water plays an important role in the design of the area of the lower reaches of the drainage and drainage structures of hydraulic structures. In particular, the complex processes associated with the flow movement in the lower reaches of low and medium pressure reservoirs play an important role in the selection of the appearance of the structure, structural elements and their shapes, sizes and location conditions. One of the important issues is to assess the strength of the elements of the lower basins of water intake facilities and hydropower plants in the current reservoirs, to determine the mode of connection of the basins, to improve the methods of quenching kinetic energy in the reinforced areas of the lower basin. Based on the 2 schemes adopted in this article, the hydrostatic pressures of several types of power extinguishers installed in the area of the water injection well, providing the bottom pound strength, were determined for the experimental device.
