Abstract
This article examines the problem, causes, and factors of floods and inundations on the Esil River near the city of Petropavlovsk from 1941 to 2020. The characteristics of floods and their consequences in the North Kazakhstan region are highlighted and described.The long- term course of discharge and water level on the Esil River – Petropavlovsk city is presented, as well as a climatogram of the Petropavlovsk weather station for 1941...2020. The values of the maximum water flow tend to decrease, which may primarily be associated with the beginning of a period of intense anthropogenic impact on the Yesil River. Thus, the average of the maximum water consumption and their average square deviations have decreased by 1.6...2 times since the late 60s-early 70s in connection with the creation of
