The effect of porosity of submerged break water structured on non-breaking wave transformation

Development of an innovative porous submerged breakwater structure which could be used for the purpose of coastal restoration is underway in the Coastal & Offshore Engineering Institute’s research laboratory. Prior to developing the structure, laboratory investigations on models (typifying por...
