The research methods applied include numerical and laboratory modeling. The evolutionary characteristics of solitary waves when it’s interacting with different types of obstacles such as a semi-submerged curtain wall and underwater barriers of various shapes and permeability were determined. Estimates of their effectiveness against waves were obtained in terms of reflection and transmission energy coefficients. A qualitative picture of erosion around a pile-type breakwater was obtained. It is shown that erosion occurs on both sides of the breakwater and the main parameter that determines its intensity is the distance between piles. Turbulent and water exchange processes generated by a solitary wave around a submerged barrier and at a sudden drop of water depth are described. The type of interaction of a solitary wave with the barrier is shown to depend on the ratio of the incident wave amplitude to the thickness of the water column over the obstacle.
