Abstrakt: The requirements on the models for computing volumes and areas of contaminated zones of water reservoirs by suspended materials and other admixtures imply that multiscale turbulence, suspension sedimentation, attachment conditions for suspended particles at the water–bottom boundary, jet effects, and salvo discharge of soil must be taken into account, which allows more accurately evaluating the spatial distribution of the concentrations of the pollutants and the dimensions of their impact zones. In this study an improved set of coupled transport models of suspended matter and sediment is described, which takes into account the dynamic variations in the calculation domain, the variation in the medium's density due to suspensions, and their multicomponent character. A model for calculating the suspended matter in pollution zones in the presence of wave processes is developed in which the dynamic restructuring of the calculation domain appears not only due to the variation in the geometry of the level elevation function but also due to the variation in the bottom relief due to the suspension's sedimentation.
