“…The use of experimental measurements associated with the simulation of various offshore environments has many limitations due to the cost, space, and material [1]. While the use of the analytical approach to study and measure the reflections and transmissions, due to wave-structure interactions is limited just to the linear wave cases [2,3]. That is the reason why the numerical simulations technique has been developed and played a key role in many potential applications [4][5][6][7][8][9][10][11][12].…”

The purpose of this work is to study the feasibility and efficiency of Generating Absorbing Boundary Conditions (GABCs), applied to wave-current interactions using the Method of Fundamental Solutions (MFS) as radial basis function, the problem is solved by collocation method. The objective is modeling wave-current interactions phenomena applied in a Numerical Wave Tank (NWT) where the flow is described within the potential theory, using a condition without resorting to the sponge layers on the boundaries. To check the feasibility and efficiency of GABCs presented in this paper, we verify accurately the numerical solutions by comparing the numerical solutions with the analytical ones. Further, we check the accuracy of numerical solutions by trying a different number of nodes. Thereafter, we evaluate the influence of different aspects of current (coplanar current, without current, and opposing current) on the wave properties. As an application, we take into account the generating-absorbing boundary conditions GABCs in a computational domain with a wavy downstream wall to confirm the efficiency of the adopted numerical boundary condition.

“…In the case of weakly nonlinear waves, the amplitude of the n-th free harmonic tends to increase in proportion to the n-th power of the input wave amplitude, while in the case of strongly nonlinear waves it will approach a constant value. Errifaiy [24] investigated the analytical method to determine the coefficient of reflection throughout the wave-current-plate interactions; the study focuses just on current effect using the evanescent modes model which had a good agreement with the experimental results. Later, Naasse [25] has carried out the same study by investigating the effect of geometrical parameters.…”

“…On other way, submerged plate breakwater is studied experimentally, theoretically, and numerically. Moreover, the wave-plate-current interactions are further studied recently by Errifaiy [24], but the experimental and numerical investigations are also still also laky. However, the theoretical investigations of wave-plate-current interactions are limited just to the current with the same direction as the propagation of the incident regular wave.…”

The purpose of the work is revolved around presenting a literature review applied to wave-structure interactions. During this literature review, three types of breakwaters are presented: Bottom submerged breakwater, submerged plate, and seawalls breakwaters. Further, a numerical method used recently to study wave-structure interactions is presented. Furthermore, a simple analytical model is illustrated. Next, an experimental technique then also is depicted. For more details, this review will focus clearly on submerged bottom breakwater in discussion section for the reason of the importance of this breakwater for many hydrodynamic applications. Finally, valuable remarks will be deducted in the conclusion section.

“…In 2019, Ning et al [15] used the potential theory to estimate the forces and moment on a submerged plate induced by the wave-current interaction. In 2016, Errifaiy et al [16] conducted an analytical study of the wave-plate-current interaction, and the study was based on the potential theory linearized with the model of evanescent modes. Thus, they introduced in 2019 the influence of geometric parameters on the reflection coefficient [17].…”

The aim of this work is to propose a numerical study of the interaction of a wave-horizontal plate fixed and completely immersed in a flat-bottomed tank with a uniform current flowing in the same direction as the incident wave. We investigate in particular the effect of the plate at minimizing the impact of the wave on the coast of beaches by studying the free surface elevation and the reflection coefficient, as well as the influence of the various geometrical parameters on the latter, taking into account the presence of the current. The numerical method used in this study is the boundary element method (BEM), and the results obtained will be confronted with experimental and analytical data existing in the literature.
