Description
Summary:The article is devoted to the mathematical modeling results description of hydrodynamic processes in seas mouth areas. 3D hydrodynamics mathematical model description is given, which is used to calculate the 3D velocity vector fields of the aquatic environment movement in mouth areas. The approximation of the differential equations of the mathematical model is based on the balance method taking into account the fullness of the control areas. The use of this combination of methods made it possible to more accurately description the complex geometry of the coastline and seabed. Due to this, it was possible to reduce the calculation error at the boundaries of the computational domain and to increase the calculation accuracy. A software package for modeling hydrodynamic processes in mouth areas has been developed in C++. The description of the software package and the results of its operation are given.
