Improvement of the Volume Determination and Operating Regimes of Reservoirs
Abstract
The climatic, geographic, and demographic conditions of Uzbekistan have necessitated the development of water management, hydraulic engineering, and hydro-energy since ancient times. Approximately 6,000 years ago, in Uzbekistan, rainwater collection for irrigation (liman irrigation) involved constructing artificial ponds to regulate and properly distribute existing water resources, thus ensuring small areas of land were irrigated.
The experience of transferring water from one region to another to improve water supply was also acquired.
The task of creating and maintaining water reserves to ensure the timely and uninterrupted supply of water to consumers and users from reservoirs is also crucial. Currently, it is required to know the exact volume of water that can be accommodated in any reservoir during its operation, especially if the reservoir has been in use for many years.
Taking this into account, the Namangan region Reservoir Utilization Administration and the Scientific-Research Institute of Irrigation and Water Issues "Scientific-Research Consulting Center for Water-Saving Technologies" concluded a contract on May 16, 2023, for the performance of research work No. 8. In 2023, research was carried out by the "Scientific-Research Consulting Center for Water-Saving Technologies" to determine the current volume of the Eskiyer Reservoir.
To determine the current volume of the reservoir and the amount of sediment in the basin, modern GPS-equipped SONTEC S5
Doppler-profiler echo-sounders, Deeper CHIRP+ profiler GPS devices, HD-MAX echo-sounders, Garmin Etrex Vista GPS devices, and Sprinter 250 M levels manufactured by Leica, along with their GSS111 No. 741882/1 and No. 741882/2 (five-meter) barcode staff gauges, were used.
