In the natural current of water, the growing bed movement leads to a reduction of reservoir volume and canal cross-section area, filling by forebay of pump station and hydroelectric station pressure basins with sediment. This leads to abrasive wear of pumps, water turbines, and pressure pipelines, as well as other negative consequences. In many countries, rivers come laden with a large amount of sediment and enormous costs. At determining of sediment discharge it is important values of height and movement velocity of bed ridges. The determination of these values is based on experimental studies was not taken into account the heterogeneity of sediment with different fractions. For this reason, the calculated values according to obtained formulas have large discrepancies with field data. To eliminate these discrepancies, experimental studies were conducted using six types of fractions with the same weighted average diameter. Based on of laboratory data diagrams and interrelation were obtained for ridge length, height and movement velocity from sediment hydraulic and geometric sizes.
