Evaluation of sedimentation of water reservoirs with modern technologies

Abstract

When dams are built, sedimentation accumulation starts in high-fuzzy; after filling of dead volume happens, blurring of useful volume, and the efficiency of the reservoir decreases. In this research, the Chartak reservoir in the Namangan region. In this study, the ArcGIS application was used with the ArcMap program. Originally Sentinel 2 Satellite images were downloaded free of charge from Glo Vis US official website. The unstable reservoirs were selected for the length of the reservoir. For each reservoir, the dependence of the water level on the flow rate was calculated, thus analyzing the sediment movement. The research results showed that 10 control points were taken, where Q was the same. In the first control point, in which all value was a bit lower than others, Q was 5, followed by 310 in B, 3.4 in H, omega had 1081.3, and 4.6 in ϑ.
