Assessment of the productivity of river sediments

Abstract

Abstract. the fractional and chemical composition of the river sediments in the "Sokhsoy" stream and in the " Ong gyorq" reservoir were studied and the possibilities of their use were analyzed. In the study of this process, the fractional and chemical composition of fluids moving along with water in the clarifier and the change of their share in water along the length of the clarifier were considered as the main factors. Particles with a diameter of 1.0 - 0.05 mm and 0.05 - 0.001 mm make up the main part of the fractional composition of suspended solids in the clarifier , and their average total share is 56% of 1.0 - 0.05 mm particles at the inlet of the clarifier, and 56% at the outlet It was determined that 29%, 0.05 - 0.001 mm particles make up 43% in the inlet and 70% in the outlet. It was studied that the chemical composition of the river discharges has a special feature, and that the crop fields are rich in sources of nutrients necessary for plant development. Based on the obtained results, conclusions are given on the possibility of regulating the amount of chemical compounds by controlling the distribution of river discharge in the clarifier.
