Intra annual water flow distribution of the right-bank confluents of ertis river within the boundaries of the Republic of Kazakhstan

Abstract

The questions of methodic of calculation of intra annual water fl ow distribution of the main rivers of Ertis water basin right bank were investigated. There was conducted a comparative analysis of the obtained results for the last thirty four years and the results shown in “The resources of the USSR surface waters” in the area of research, and also the results obtained in a period with conditionally-natural water flow (1933-73).
