Analysis of fractional and chemical composition of chartak reservoir sludge sediments

Abstract

Abstract In the present era, when climate change has become a global problem, efficient use of water resources is becoming an important task. Natural field research was conducted in Chartak reservoir. In order to determine the amount of turbidity entering with the flow, the characteristic tributaries were determined along the length of the reservoir, and in each tributary, samples were taken using a bathometer at different times of the season and filtered in laboratory conditions. According to the analysis of the results, the average amount of incoming turbidity was 0.3-0.5 g/l, and the amount of outgoing turbidity was 0.05-0.08 g/l. Samples of the sediments that sank into the reservoir bowl were taken and their fractional and chemical composition was analyzed in the laboratory of “Gidroproekt” JSC. According to the fractional composition of muddy sediments, particles with a diameter of 1.0-0.5 mm are 13.98%, particles with a diameter of 0.5-0.25 mm are 11, 49%, particles with a diameter of 0.25-0.10 mm - 7.56%, particles with a diameter of 0.10-0.05mm - 10.48%, particles with a diameter of 0.05-0.01 mm - 26.8%, it was found that particles with a diameter of 0.01-0.005 mm make up 13.34%, and particles with a diameter of 0.005-0.002 mm make up 16.42%. If we pay attention to the distribution and share of sediments on the walls, 35-40% of particles with a large fraction (d=1.0-0.1 mm) and 50-60% are particles with a small fraction (d=0.05-0.001mm). It is based on the presence of particles rich in microelements useful for agricultural fields in sediments.
