The paper presents a parallel implementation of the wave hydrodynamics model and the modern SWAN wind-wave model. The paper presents the results of parameterization of vertical turbulent exchange using filtered expedition data, which are included in the hydrodynamics model to clarify the coefficient of turbulent exchange inhomogeneous vertically. As input data in the models, the contours of the image of the Sea of Azov are used, determined by the method of a local binary template obtained from the WorldView satellite. The results of numerical experiments obtained on the basis of SWAN and a three-dimensional model of wave hydrodynamics are presented, and their comparison is carried out. The article describes the parallel implementation of SWAN, calculates the indicators for evaluating the parallel computational efficiency of SWAN, determines the computational scalability of SWAN depending on the number of computational threads. The indicators for evaluating the parallel computational efficiency of a three-dimensional wave model of hydrodynamics are presented.
