Abstract
This paper presents the results of wave regime hydrophysical characteristics calculations in the area of the accumulative shore of the Tsimlyansky reservoir northwestern part. Wave hydrodynamics model based on 3D mathematical model that includes three Navier-Stokes motion equations, the continuity equations for an incompressible fluid was used. The discretization of the hydrodynamic equations was performed using the pressure correction method. Numerical algorithms and the software package implementing them are used to determine the pressure field, the water medium velocity vector field and to plot the pressure a given section of the reservoir water area. The results of the study can be used in the study of hydrophysical processes, assessment of the hydrodynamic impact on the formation of the coast-line and the bottom relief of large plaintype reservoirs in the Southern Russia.
Highlights
Reservoirs play an important role in the water management complex of Russia
In Southern Russia, where there is an acute shortage of water resources, especially in the spring and summer period, the development and implementation of measures aimed at preserving and improving the hydroecological state of water reserves is extremely important
The Tsimlyansk reservoir belongs to the category of large ones
Summary
Reservoirs play an important role in the water management complex of Russia The creation of these water bodies is aimed at ensuring the regulation and redistribution of river flow over time, guaranteed water supply to the population, meeting the needs of the population for energy resources, protecting territories from floods, etc. For the water area of the Tsimlyansky reservoir, the results of the study and parallel numerical implementation of a nonlinear 3D model of wave hydrodynamic processes are presented. The developed algorithms for solving model problems and their numerical implementation in the form of a problem-oriented software package have a wide practical application for studying wave processes of coastal systems of the same type of water bodies and their hydrodynamic impact on the territory of the coast.
