Abstract (EN): Submerged breakwaters ale being used as a possible solution in the prevention of coastal erosion problems. They guarantee increased protection between themselves and the coastline, diminishing the risk of coastline erosion and assisting sand accretion or retention. Their efficiency depends on the relationship between the incident wave height and the corresponding reflected wave height, to achieve the required protection with the minimum impact on the environment. Whenever a submerged breakwater reflects waves, not all of their energy is reflected; some of it is absorbed and some of it is transmitted through the structure. In our research, wave reflection was analysed using a full wave energy concept. The potential and kinetic wave energies were determined and the reflection coefficients established. The Laser Doppler anemometry technique was used for measuring velocities at the wave tank of the Hydraulics Laboratory of the University of Oporto's Faculty of Engineering.
