USE OF MODERN TECHNOLOGIES IN DETERMINATION OF HYDRAULIC AND HYDROLOGICAL PARAMETERS OF WATER RESERVOIRS

In this research, an analysis of natural field research results, which was conducted in the Chartak River Reservoir was given. During the field research, different measurements were carried out to determine the useful volume of reservoirs using modern measuring instruments. The research was carried out as following: hydraulic parameters are studied in the aquatic part of reservoir using “SonTekS5” river surveyor doppler, and geodetic measurement were obtained in the waterless parts of the reservoir using “N-3” surveyor levelling tool. Measurements were taken in the defined characteristic cross section and the results on cross section were extracted. Conclusions on the amount of turbid sediments in the reservoirs were made through analyzing the results of the field research and statistical comparison of long-term data of the reservoir. Based on the measurement data, cross sections of the reservoir were formed, and comparing the obtained results with the design parameters of the reservoir, the volume usefulness was clarified. According to the pertinent results of the research, the current usefulness and sediment volumes were 20.81 million m³ and 9.19 million m³, respectively.
