Abstract:

This paper investigates the influence of human activities on the runoff depth of the spring flood of the rivers Zhayyk, Ilek and Tobyl in Kazakhstan. Statistical characteristics of the runoff depth of the spring flood of these rivers before and after the construction of the reservoirs, as well as for the long-term period of supervision, are analyzed based on actual and restored data. Values of the runoff depth of the spring flood of various frequencies were calculated. Series of observations on homogeneity conducted by graphical and analytical procedures were checked. Total integrated curves of the runoff depth of flood during the spring season were developed. Series of observations of the runoff depth of the spring flood were analyzed for homogeneity by means of Student and Fischer's criteria. The analysis revealed that as a result of reservoir construction, the spring flow is not complying with the hypothesis of homogeneity.
