【 摘 要 】

Article deals with a fractional and chemical composition of sediments from the sediment reservoir in Ilyash village, Ferghana region, Uzbekistan (Syr Darya river basin) and analyses their feasibility. As a key factor in the study of this process was considered the fractional and agrochemical composition of sediments moving with water in the sediment reservoir, and the change of their share in the water along the length of the reservoir. The main composition of the sediments in reservoir consists of fractions >0.25 and 0.25–0.01 mm, with the average fraction of 69% in the inlet and 60% in the outlet. The river sediments are rich in minerals important for the irrigated cropland. Based on the results we conclude that it is possible to regulate the number of chemical compounds in the water by controlling the exploitation regime of reservoir and the sedimentation process in it.
