Abstract

Increasing anthropogenous load for river-beds brings about improvements over the existing methods for computation of basic hydrological characteristics. Extraction of sandy-gravel mixture (SGM) from river-beds exerts substantial influence on mechanisms of sediment transport. Giving qualitative and quantitative estimation of the influence is possible by way of employment of experimental research results. Results of a full-scale study of conditions for sediment transport formation in the segments of the Dniestr with river-bed pits for the period that encompasses various stages of their working are presented in the paper.
