A laboratory investigation on a single row of suspended porous pipes was conducted in a two-dimensional regular wave flume to study their hydraulic performance. The wave energy losses at the structure were computed and the effects of depth of submergence, incident wave steepness, water depth, pipe diameter, percentage of perforations, size of perforations and relative wave height on loss coefficient were studied. It was found that as incident wave steepness increases, loss coefficient K <inf>1</inf> increases. Water depth has insignificant effect on K <inf>1</inf>. It is also observed that as percentage of perforations increases, K <inf>1</inf> increases. For the range of variables studied, as the relative wave height increases, K <inf>1</inf> decreases.
