## 5 Hydraulic and Energetic Behavior
The characterization matrices of the annual waves in these points, obtained with CMS Wave, are shown in Tables 4-7. Figure 11: Cont. Figure 10: Villano-Sisargas-Punta Langosteira breakwater, index 28, index 145, index 139. As the results reveal, while the highest energy points in the sites are those that are furthest from the coast, those that are located near the coast have the lowest energy potential. For this reason, the location of the different wave power plant is chosen where there is greater energy potential and where the installation is constructively feasible. It must be taken into account that the installation of the devices in the head and directions changes of the breakwaters are not the most convenient site, because major waves appear more frequently, which could put in danger the stability of the device. To estimate the power output at a given site with the help of the converter of wave energy, the wave characterization matrix of the location was used (table Hs-Tp in hours) together with the power matrix of the WEC [27; 28]. Apart from the incident wave height or wave frequency, there are other parameters that are highly influential in the process of capturing the wave energy, such as the power take off damping of the devices [29]. However, this need to be proven as an experimental parameter, and has not been taken into account in this paper. Figure 11: Cabo Peñas-Gijon port, index 117, index 137, index 169. For the choice of the power matrix of the OWC [25], the following matrix of power was obtained from a study for the installation of a plant in the port of A Guarda (Portugal) (see Table 8). In order to decide the power of the turbine to be used, studies were conducted for the OWC in A Guarda, where tests were carried out with turbines of 45, 100, 150 and 200 kW. However, for practical purposes, the existing plant in the Mutriku dike (Basque Country), which has 16 cameras, was also used. Each chamber has an 18.5 kW turbine of power, adding together at a total installed power of 296 kW. For this reason, it was decided to use 50 kW turbines for the OWC to be installed in the breakwaters. The power matrix used for the SSG device [30; 31] is shown in Table 9. It was obtained from the Multi-Stage turbine, developed by the Norwegian company WAVEnergy AS [17], which built the first SSG scale prototype on the island of Kvitsoy (Norway) and installed this turbine model. The power installed in an SSG device 10 m section is 155 kW. Figure 12: Bilbao-Vizcaya buoy—Punta Lucero breakwater, index 30 and index 89. \begin{table}
