ABSTRACT
This paper presents an assessment of changes in maximum flow values (maximum discharge, m3/s) of the spring flood caused by human activities on the rivers Zhayyk, Ilek and Tobyl. Statistical characteristics of the maximum discharge of the spring flood of these rivers for the period of 1940-2012, 1938-2012, before and after the construction of the reservoirs, as well as for the long-term period of supervision are analyzed based on actual as well as restored data. Values of the maximum discharge of the spring flood of various provisions are calculated. The total integrated curves of the maximum discharge of the spring flood are constructed.
