The results of a long-term supervision for changes of bed and hydraulic conditions in rectified rivers-water intakes and transformations of the beds are analyzed. The process of the formation of the dynamically stable bed parameters as a result of accumulation of silts and their removal onto the bottom land is considered. The diagrams of the dynamics of the average weighted layer of silts are made. The linear profiles of the experimental Moroch river are shown. The integral epures of the alluvium balance are made. The integral curves of the river bed deformation for the different piquets are constructed. The hydro graph of the water discharge of the 1979 year flood is made. The systematic approaches for the prediction of the dynamics of erosion accumulating process within the area of interaction of the bed and bottom land fragments of the stream flow so enabling to determine the tendency of the bed deformation processes are suggested
