As a result, the problem is reduced to an analysis of the theory of dynamical systems. The evolution of the state is shown and analyzed. A qualitative analysis of shore abrasion as an ecological system is presented on the basis of a simplified model that is described by a system of ordinary nonlinear differential equations. The semiempirical model used is based on consideration of the averaged quantities. The propagation of surface gravitaty waves with simultaneous excitation of two spaced bottom sources with further influence on this propagation of waves by time-repeated pulses is investigated. It is shown that repeated pulses in time both increase the generation of waves and weaken them. It is noted that for the problems of interaction of waves with bank reinforcement structures, existing numerical models allow describing the run-up of waves onto coastal slopes with a wide range of parameter changes. The results of experimental studies of the process of wave run-up on a vertical wall are presented.
