Numerical Analysis and Prediction of the Consequences of Natural and Technological Impacts in Coastal Areas of the Azov Sea

In this work, the waves and currents generated by prognostic wind in the Sea of Azov are investigated using a three-dimensional nonlinear sigma-coordinate Princeton Ocean Model. The mathematical model was also used for studying the transformation of passive admixture in the Sea of Azov, caused by the spatiotemporal variations in the fields of wind and atmospheric pressure, obtained from the prediction SKIRON model. Comparison of the results of numerical calculations and the data of field observations, obtained during the action of the wind on a number of hydrological stations was carried out. The growth of storm surges, velocities of currents and the characteristics of the pollution region at different levels of intensity of prognostic wind and stationary currents were found. The obtained results are presented in the table of the sea level changes caused by the onshore and offshore winds and the current velocities for different characteristics of constant and variable wind. The results of a comprehensive study allow reliably estimate modern eco-logical condition of offshore zones, develop predictive models of catastrophic water events and make science-based solutions to minimize the possible damage.
