Abstract
The work aims to study the climatic conditions of the upper Kafirnigan River to determine the contribution of territories of different heights above sea level of the Kafirnigan River basin in the formation of river flow and correlation dependencies of meteorological parameters of the upper river and coastal areas to the Nurek reservoir to identify the influence of the reservoir on climatic characteristics. The Bustonabad meteorological stations of the upstream Kafirnigan River and the Fayzabad, Dangara, and Javan meteorological stations coastal the Nurek reservoir is used. Due to the lack of a meteorological station dedicated directly to monitoring the meteorological characteristics of the upstream Kafirnigan River, correlations of the Bustonabad meteostations data located on the border of the river basin carrying out. The atmospheric precipitations and Kafernigan water discharge correlations coefficient (0.71) were found. Assuming the influence of the Nurek reservoir with a water volume of 10.5 km3 on the climatic characteristics of the Kafirnigan River upstream and coastal areas correlations of temperatures and precipitation between the data of the Bustonabad meteostations and the coastal areas of the Fayzabad, Dangara and Javan reservoir were studied.
