Some solutions to improve the efficiency and environmental safety of reservoir use

Abstract

Abstract Flood and landslide control and unhindered management is a global problem worldwide. In high-water years, it is advisable to control the volume of water in reservoirs, taking into account such factors as increased loads on them, due to siltation and sedimentation of soils. In particular, in years with hydrological security of more than 75%, it is necessary to direct the main part of floods and mudflows into the lower stream, for this it is recommended to keep the water level as close as possible to the level of useless volume in high water, and water pumps should operate at full capacity during the passage of floods and downpours. In years when the water consumption of the water source is above 75%, the months of April and May are considered sufficient to create water reserves in high streams. Also, in years when the water consumption of the water source is less than 50%, it is necessary to collect mudflows and floodwaters to create the necessary water supply. In such conditions, it is recommended to carry out the dynamics of stopping water discharge at high temperature as follows. It is advisable to distribute the useless volume of water between the precipitation zones of dense flow and the normal water level in the upper boeuf. Based on this, it is necessary to install “Hydraulic posts” on the upper reaches of reservoirs, with the help of which it is possible to control the transformation of water flows.
