The lines of approaching water industry problems in the Lower Don regions
Summary
Most topical issues related to the water deficiency in the Tsimliansk water reservoir are considered. Water shortage in the given water reservoir results in tangible difficulties in the supply of the required water amount to almost half of the Rostov Area residents and to Novocherkassk Hydropower Station. Blue-green algae growth in the water reservoir during the summer period and reduction of fish population are equally serious problems. The construction of Bagaevsk hydroscheme is proposed as a solution of the Tsimliansk water
reservoir shallowing problem. Commissioning the Bagaevsk hydroscheme will improve the conditions for the Rostov Area fish farms; replenish the Manych River and lakes which provides more opportunities for fish spawning. The construction of a fish bypass canal in the Don River flood plain will provide for fish moving for spawn eliminating the hydroscheme. The problem of unsustainable water use in the Tsimliansk water reservoir and Don River for irrigation is considered. The proposed method provides for calculating backup
seepage from the canals in the earth canal and lining, in particular of the Don main canal and lateral distribution and main canals. The lines of approaching the problem of water resources shortage in the Lower Don Area are proposed. Among these are thorough investigation and revision of water resources input and output of the water reservoir for dry year periods, measures on water losses reduction, commissioning the Bagaevsk hydroscheme, possible implementation the project of the «Volga–Don–2» Canal construction.
