THE STUDY OF THE PREREQUISITES OF THE FLOOD SITUATION ON THE RIVER ISHIM

Abstract

The nature of the flood situation on the Ishim river, near the city of Petropavlovsk, as practice shows, does not always have predictable consequences. This situation has been observed especially in recent years, the most striking event is the spill of 2017, when the water level in the river rose to the maximum value of the dam cutoff, and in some places it was necessary to increase the shaft to prevent the further spread of flood waters. It is obvious that the flood situation is influenced by many factors, among which there are two main ones: the moisture reserve in the form of snow cover and the spring temperature profiles that affect the dynamics of snow melting. Both indicators are subject to high dynamics, which emphasizes the importance of continuous monitoring of this process and the creation of an analytical model reflecting the visual boundaries.
