The article describes the numerical model of the fl ow that envelops the shore protection structure in the form of a stream spur. Various from the point of view of permeability, spur body material options are considered. To model turbulent fi ltration as local resistance in the fl ow, a formula is proposed that relates the fi ltration coeffi - cient to the hydraulic resistance coeffi cient of a permeable medium. As a result of the simulation, images were obtained in the form of a planned distribution of velocities and pressures in the vicinity of the structure. The obtained materials indicate the relative position of the transit and whirlpool zones of the fl ow. Conclusions are drawn about the nature of the stream fl owing around the shore protection structure and the eff ect of fi ltration in the body of the structure on the characteristics of this stream.
