The dynamics of nearshore wave—current interactions is investigated. A coupling model for the description of nearshore currents, storm surges, surface waves, and morphodynamic processes is developed. Economical schemes of time integration and TVD-approximation of advective currents allowing the description of the fields with high spatial gradients are used. The developed model is used to provide the hydrometeorological design of hydrotechnical constructions in the Black and Azov Sea nearshore area. The monograph is intended for administrative institutions, research and design institutes, and natural departments of the universities.
