SPATIAL-TIME VARIABILITY OF THE ILE RIVER RUNOFF UNDER CONDITIONS OF ANTHROPOGENIC ACTIVITY

Abstract

To solve the problems of sustainable management of water resources in the catchment area of the Ili River basin, it is becoming demanded to study the dynamics of the average annual water discharge, taking into account anthropogenic activities, since their intensity is constantly growing. At the same time, the integral indicator of natural conditions in the catchment is the average annual water discharge of river basins, and the importance of this parameter lies in the fact that they can be considered as a function of the response to any changes in the catchment. In this regard, the analysis of changes in the average annual water discharge of the Ili River basin's catchment area was carried out on a spatio-temporal scale, where linear trends were used to assess and plot graphs, the method of multiple regression analysis and processing of time series were carried out on the basis of Microsoft Excel. Analysis of the dynamics of the average annual water discharge in the Ili River basin's catchment area on a spatio-temporal scale showed that, despite significant variability over the years, all studied hydrological stations are characterized by general patterns of changes in the hydrological regime under the influence of anthropogenic and natural factors.
