The aim of investigations is to develop mathematical models and experimental investigations modeling both the wave processes at the presence of underwater obstacles and jet flows and the interaction of wind waves with hydroengineering constructions of different types. The aim of investigations is realized by means of the state of corresponding boundary value problems on the basis of constructed models and by the construction of engineering methods for calculations of the new types of coast-protecting structures. New models of nonlinear wave transformation are proposed and evolution equations are developed; a new nonlinear model for investigations of salt sea water displacement is presented; analytical solutions of a new problem of wave propagation in stratified fluid are obtained; the method of calculation of energy alongshore currents at the wave transformation zone on the basis of Longuet-Higgins model is developed; the equations described the nonlinear Stokes waves in the water of variable depth are derived; the engineering methods for calculation of running up wind waves on a complex cutting and the volume of bay erosion are developed. The results of investigations and SIW developments have been introduced in the Ukraine economy for protection of drawing canals and coasts of Azov and Black seas Product Description popup.authors popup.nrat_date 2020-04-03 Close
