Marine sponges influence the flow hydrodynamics by suction/pumping mechanism. They provide a recirculation and remove pollutants from their residence. Previous studies have validated efficacy of mimetic in improving momentum transfer marine environments. This study endeavors to explore impact wave characteristics (i.e., height period) on near sponges. Both physical numerical simulations were undertaken this phenomenon. Experimental results unveiled that efficiency sponge is contingent upon some circumstances. When waves short period height, suction effects prevail. In such cases, orbital velocity tends be negative direction, leading suppressed fluctuating velocities reduction turbulent kinetic energy throughout water column. Thus, penetration shear layer column occurrence wake-street diminish. Conversely, an increase enhances exchange through Surface Line Integral Convolution Three-Dimensional stream trace visualizations using OpenFOAM insights into generation spirals vortices induced
