Brittany), is selected for demonstration of tidal current conversion technology by Sabella company. The second site - Strait of Dover in the eastern English Channel, has been considered till now as promising. The resource assessment is performed using surface velocity time series recorded by High Frequency radars (HFR) and ADCP velocity measurements in the radar coverage zone. Combination of two sources of data allowed to characterize the current velocity variation in three spatial dimensions and in time which increased confidence in hydrokinetic resource assessment from the radar data. In the Strait of Dover, the most energetic area is found west of Cape Gris Nez, with flow velocities exceeding 1 m/s observed more than 50% of time there. The mean power density attains 0.9 kW/m2 in the surface layer. In the bottom layer the power decreases by the factor of three. Higher resource is identified at two sites in the Iroise Sea (Fromveur Strait and NW of the Ushant Island) with the mean power density in the surface layer ranging from 2.7 to 3 kW/m2.Show less >
