Irrigation and Melioration


To clarify the granulometric composition of the deposited sediments at the inlet head of the water intake of the outlet of the Tupolangskiy reservoir, samples of bottom sediments were taken and their granulometric composition was analyzed in laboratory conditions. Near the water area of the water intake of the 1st tier of the Tupolang reservoir, the deposited sediments are represented by smaller particles, the diameter of which ranges from 5 mm to 0.1 mm and their percentage is 95%. The main results on the calculation and substantiation of the parameters of the hydraulic elevator for cleaning the water area of the inlet head of the water outlet of the first tier of the Tupalang reservoir are presented. In determining and substantiating the main standard sizes of the hydraulic elevator, theoretical and experimental research methods were used, as well as the method of S.M. Shtin.
