Description
Summary:— Hydropower plays a very important role in the socioeconomic development of Kyrgyzstan. The Naryn River is formed in the high mountains of the inner Tien Shan, flows through the territory of Kyrgyzstan and Uzbekistan, and has one of the most extensive basins in Central Asia, with significant hydropower potential. A cascade of hydro power plants (HPPs) has been built on the river, which supply the country’s electricity needs and provide annual and long-term regulation of water use in the region. New HPPs, including the Kambarata-1 HPP, the largest HPP of the cascade, with a rated capacity of 1860 MW, are currently being designed to increase power generation. The future reservoir of this HPP requires a comprehensive study and determination of all parameters for a detailed assessment of the environmental impact, as well as for ensuring reliability and economic efficiency of its construction and operation. The bed of the future reservoir is located in a remote mountainous area; therefore, in this work, computer modeling and calculation of its volume and surface area are performed on the basis of freely available global digital surface models (DSMs) and digital terrain models (DTMs) using geoinformation technologies. A comparative analysis of the capabilities of freely available global AW3D30 DSM, ASTER GDEM V003 DTM, GLO-30, SRTM Plus, and NASADEM with a 30-m spatial resolution for application in hydrological modeling is conducted. Based on the selected AW3D30 DSM, the volumes and surface areas of the reservoir at different water levels are determined. The obtained results indicate the possibility of using modern DSMs and DTMs based on space data in the design and operation of reservoirs in the mountain conditions of Kyrgyzstan.
