Assessment of changeability of water balance elements of high water and low water of the Volga river basin
The results of the analysis and assessment of changeability of water balance elements for the periods of spring high water and low water on 11 private reservoirs and in whole on the Volga river basin are given. In the Volga river basin four water-economic areas are singled out according to the conditions of stability of basic statistical parameters of water balance elements and also their inner and inter series connection. There is also considered a dynamics of variability of elements of water balance of the river Volga in space and in time. The equations of relationship are received which determine values of the river flow for the periods of high and low water depending on climatic factors.
