The article deals with the runoffs of rivers falling into the Kapshagai Reservoir. By the conditions of the formation and the nature of interaction of water resources, the area under study is zoned into three areas: 1) the area of formation of water resources; 2) the area of alluvial cones and intense flow dispersion; 3) the area of groundwater discharge in the beds of numerous Karasu rivers. It also describes the special instrument studies of the relationship of the surface and ground waters in the selected rivers, and contains a developed technique of field study of the runoff changes along the length of watercourses in the presence of reaches of both loss of the surface flow and discharge of the groundwater flow. The instrumental gauging of the channel water cycles of rivers (CWC) was carried out under the supervision and with the direct participation of the author. https://www.biotech-asia.org/vol12no1/regularities-of-runoff-formation-of-rivers-falling-into-the-kapshagai-reservoir/ Watercourse; Runoff; Natural; geographical areas; River basins; Channel water cycle
