| Summary: | The information about the evolution of the bottom topography in the construction area is necessary in the design and construction of hydraulic structures in sea, as well as information about possible deformations of the bottom caused by both natural reasons and the appearance of new hydraulic objects in the waters. In the given research the authors propose an analysis of lithodynamic processes in the area of the construction of the bridge across the Kerch Strait. Several physico-mathematical models were used for calculation and description of lithodynamic processes in the construction site of the Kerch Bridge. They may be divided into two groups: atmospheric and water. Many important properties of hydrometeorological conditions may be obtained only by modeling. The model WRF is used in the research, which is applied in many foreign and domestic centers for simulation and forecast of regional atmospheric circulation due to its high quality and ease. The main steps of the calculations are provided: beginning with the collection of basic information up to combining the results of numerical experiments on several mathematical models. Special attention is paid to sedimentation and erosion associated with construction of temporary piers and waterways to them.
