The role of the increased runoff in the suspended sediment transport of the Selenga basin rivers

The conditions for the formation of suspended sediment runoff during the passage of high water flows on the rivers in the Selenga basin are considered. Seasonal and diurnal changes in water turbidity due to fluctuations in the water level of rivers are identified. The relationship governing the formation of the connection between turbidity and water flow, the predominant type of which in the basin is the simultaneous occurrence of the maxima of these characteristics, with high rates of rise and fall of turbidity are studied. It is shown that increased runoff (flood, summer flood period) determines the value of the annual sediment flow (up to 99% in years of high water content).
