Studies of northern river systems of the Kyrgyz Republic

Talas river basin, Issyk-Kul lake basin and Chychkan, Bala-Chychkan river basin

Abstract

The study of mountain rivers is now more relevant than ever when not only the climate is changing, but also many other factors have appeared that affect the hydrological process. The work is devoted to clarifying the reasons for the trends in the decrease in the magnitude of the long-term runoff of the Chychkan and Bala-Chychkan rivers under the conditions of climate change, located in the Ketmen-Tube basin. The study of little-studied rivers lowing into the Toktogul reservoir is caused by the economic and social significance of this water body. The data which were used for this study were obtained from several resources as Hydroposts and meteorological stations. To determine the role of individual climatic factors on the runoff of the Chychkan and Bala-Chychkan, Talas rivers, linear trends were calculated based on the data of all meteorological stations.
