This study analyses the application of mathematical modeling for the examination of specific characteristics of the storm surges formation in the Taganrog Bay. The simulation of storm surges in the Azov Sea was performed with consideration of the mouth area of the Don River. The Surface Modeling System (SMS 11) made it possible to construct an unstructured triangulated mesh for the whole Azov Sea including coastal areas. According to ADCIRC model results features of water circulation in the Don River mouth area were identified. The numerical experiments have demonstrated the specifics of storm surge distribution in the delta channels and in the Don River mouth. Depending on the wind speed the storm surge has a maximum height in the river mouth. Apart from the level of storm surges the ADCIRC model visualizes the currents speed and directions, while a small-scale mesh allows seeing the structure of the coastal currents in the delta’s channels.
