ASSESSMENT OF FLOW FLUCTUATIONS IN THE OYIL RIVER UNDER NONSTATIONARY CLIMATE CONDITIONS
Abstract.
This article deals with the issues of changes in river flow in the Oyil River basin caused by nonstationary climatic and anthropogenic conditions. To assess the hydrometeorological characteristics of the study basin, we used data from the published cadastral materials given in "Basic Hydrological Characteristics", "Multiyear Data on Surface Water Regime and Resources", "Surface Water Resources", "Hydrological Yearbooks" as well as Internet sources. Using well-known statistical processing methods, hydrometeorological characteristics of river runoff were analyzed, graphs and histograms were plotted, which in turn show changes and fluctuations in precipitation, air temperature and river runoff. Hydrological series of hydrometric gauges of the Oyil River basin for the period from 1940 to 2019 were collected and analysed to assess changes in river flow. Changes in river flow in the study basin were determined for two periods: natural and disturbed. For each period, the characteristics of the runoff of different supply were identified by constructing the distribution curves. The changes in the annual flow averaged from 1.5 (river Oyil - Oyil village) to 27 % (river Oyil-Altykarasu, river Oyil-Taisogan) in the direction of reduction. On the hydrological stations Saltogay, Altykarasu and Taisoigan the results of curves of security in the field of high stream flow show considerable decrease in flow from 35 % up to 45 % whereas in the field of low stream flow we observe increase in flow of about 250-300 %, i.e. the water flow in high stream flow has decreased, and in low-water has increased.
Key words: annual runoff, runoff rate, air temperature, precipitation, climate change, baseline period, average annual discharge, river runoff.
