Assessment of the impact of low-pressure water storage units on the environment
Incoming article date: 18.05.2019The article provides materials for research and assessment of the effect of reservoir hydro-systems on the environment. A detailed analysis of the causes and parameters of the influence of hydroelectric small hydropower stations on the hydrobtological resources of rivers. The results of the study and the assessment of the pollution level of the bottom sediments of the head node of the Kashkhatau HPP are given, which confirmed a slight excess of the permissible concentration level in terms of the content of cadmium and oil products. The main factors influencing the low-pressure reservoirs on the natural environment and on the restoration of fish river resources of small rivers are determined. According to the results of engineering and environmental studies, a comparative characteristic of soil pollution by oil products in relation to the permissible level was established, analyzing the results obtained, it was concluded that the content of oil products in the collected soil samples is within the established standards. A comprehensive assessment of pollution of water resources and soils of coastal water protection zones is given.
