Predictive Mathematical Modeling of Sedimentation and Coastal Abrasion Relief Transformation Processes

We use the complex model combining the spatially 2D bottom material transport model, the 3D suspension transport model, and the 3D hydrodynamics model. The results of numerical experiments obtained on the basis of a complex model for calculating sedimentation and changes in the relief of the bottom surface are presented, and the intensity of abrasion for the coastal zones of the Tsimlyansk reservoir with the most intense geoecological situation is estimated. Based on the developed software package, calculations of the processes of coastal erosion and changes in the bottom relief were performed, taking into account the spatial and temporal variability of relief formation.
