Fomin V. The numerical modeling of the nearshore currents and waves taking into account their interaction

The Thesis is dedicated to the research of nearshore wave-current interactions. For the first time the numerical coupling model for the description of nearshore currents, storm surges, surface waves and morfodynamical processes was developed. An overall verification of the model, including the comparison of modeling data with analytic solution and the results of laboratory experiments was carried out. On basis of the coupling model the formation of current fields and surface waves caused by stationary wind and moving cyclones in the closed shallow basin was studied. The modeling of the wave-induced nearshore circulation systems was fulfilled. The quantitative assessments of the influence of surface waves on the vertical mixing in the shallow basin were obtained. The peculiarities of currents and surface waves in the lake Donuzlav, Kerchenskiy Strait and Yevpatoria coast were investigated. The comparison of the results of coupling and separate modeling was conducted. The coupling forecast model of waves, currents and storm surges in the Azov Sea was developed. This model takes into consideration the mechanisms of flooding and drying of the shore. A good conformity between the numerical modeling results and the observation data was received. The model developed in the Thesis was used to supply hydrometeorological design of hydrotechnical constructions in the Black and Azov Sea nearshore area.
