Wave interaction with bottom standing breakwater in the presence of current

In this study, energy dissipation by bottom standing thick permeable breakwater in the presence of current is investigated by considering linearized water wave theory. The modeling of porosity of semi-circular structure is done using Sollitt and Cross model (1972) of wave past through thick porous structure (for details see [2]). To solve the associated physical problem, “The Boundary Element Method (BEM)” is used. In this technique, “boundary value problem” is converted into system of “fredholm integral equation” and subsequently converts into “system of linear algebraic equations”, which are governed using “point collocation method”. A range of different results such as “reflection coefficients” (|R0|), “transmission coefficients” (|T0|), and “energy dissipation” (ED) due to semi-circular thick porous structure in the presence of current are investigated.
