The theoretical analysis, numerical and laboratory simulations were used when researching. The aim of the research is to substantiate new ways to protect the shores of natural reservoirs from destructive processes caused by waves. Space-time parameters of solitary waves which incident on a sloping beach were obtained experimentally. It is shown that long waves that move up the slope without collapse can break during the rundown. This can lead to a different washout pattern than runup. Numerical methods were used to evaluate the efficiency of various breakwaters in reducing the destructive energy of the passing wave. It is shown that the type of interaction of waves with a rectangular barrier is determined by the ratio of the amplitude of the wave to the water column above the barrier. It is obtained that the destructive energy of the passing wave is the lowest at high thin breakwaters. Product Description popup.authors Horban Iryna M.
