A problem is based on consideration of averaging valus and reduced to the analysis of theory of the dynamic systems. Unlike the known approaches this model takes into account nonlinear effects and control (signup of beach) substantially. Propagation of surface gravity waves is investigated at perturbation by two bottom distributed sources at the impulses repeated in time. It is shown that the impulses repeated in time both strengthen the generation of waves and they are weakened. Problems are considered about propagation of linear and solitary waves at presence of the bottom inhomogeneities and influence of terms of total-absorption. It is presented the statement, solutions and analysis of initial-boundary problem for the system with complete absorption at variation of coefficient of diffusion and time of relaxation. The problem of impulsively-wave influence are considered on the ramified mining hole at closing/opening of bolt on her mouth, and also design of diphasic multicomponent filtration with phase transitions on the choice of the optimal mode of development of gascondensated deposit in the conditions of cycling process. The process of interaction of waves is investigated by physical modelling with hydrotechnical building of free-form and other, i.e. active supressing of waves at their action on coast building.
