![]() Submerged breakwaters are built to reduce beach erosion. The result of this paper may be useful in wave reflector engineering and design, particularly that of rectangle-shaped wave reflectors, as it can serve as a basis for designing bar wave reflectors that reduce wave amplitudes optimally. A breakwater is built out away from the shore in the water while a sea wall is built right. For validation, we compare the transmission coefficient values obtained from the analytical solution, numerical scheme, and experimental data. ![]() We then construct a numerical scheme for the SWEs based on the finite volume method on a staggered grid to simulate the propagation of a monochromatic wave as it passes over a single submerged rectangular bar. ![]() The rectangular SMBs are more efficient than trapezoidal ones. Wave Reflection at Submerged Breakwaters: 10.4018/978-1-59904-849-9.ch235: Several types of structures are used in Coastal Engineering with the aim of. The relative submergence depth is the most important two-term parameter. The results of an experimental investigation on the damping action of impermeable, submerged breakwaters of various shapes are presented and discussed. New formulations as a function of predict the transmission and reflection of SMB, accurately. We also measure the effectiveness of the bar by comparing the amplitude of the incoming wave before and after the wave passes the submerged bar, and extend the result to the case of n-submerged bars. The proposed comprehensive parameter () describes the responses of smooth submerged breakwaters (SMB). From the analytical solution, we derive the wave reflection and transmission coefficients and determine the optimal height and length of the bar that would give the smallest transmission coefficient. We first solve these equations for the single bar case using separation of variables to obtain the analytical solution for the wave elevation over a rectangular bar wave reflector with specific heights and lengths. over emerged breakwaters may reach 20 to 40. In this paper, we investigate the wave damping mechanism caused by the presence of submerged bars using the Shallow Water Equations (SWEs).
