Physical and mathematical modeling of permeable breakwaters

Abstract

This article presents the experimental result and mathematical analysis influences of the permeable breakwaters to dynamics of the coast on various conditions by the action of waves. Deposition of sediment behind breakwaters leads to the formation tombolo of a certain size and intensity depending on the parameters of breakwater and the presence of a weak along-shore sediment flow. The results of the experiments determined empirical dependences, which are necessary for scientific study design of permeable breakwaters. Mathematical modeling of experimental data was also carried out. Experimental data are compared with already known results of research for permeable breakwaters with frontal and oblique approaches of waves. The experiment was held in Kyiv, Ukraine at the Institute of Hydromechanics National Academy of Sciences of Ukraine.
