A laboratory investigation on single row suspended porous pipes was conducted in a two-dimensional regular wave flume to study their hydraulic performance. The effects of porosity, water depth, incident wave steepness and relative wave height on transmission and reflection coefficients were studied. It was found that (a) as incident wave steepness increases transmission coefficient K<inf>t</inf> decreases and reflection coefficient K<inf>t</inf> increases; (b) water depth has insignificant effect on K<inf>t</inf> and K<inf>t</inf> for porous pipes; (c) as porosity decreases K<inf>t</inf> decreases and K<inf>t</inf> increases; and (d) the range of variables studied, as the relative wave height increases K<inf>t</inf> increases and K<inf>r</inf> decreases.
