Abstract
Geomorphologic conditions of its coastal areas and the importance of its shipbuilding industry make of Nagasaki Prefecture a suitable location for exploitation of marine energies. The objective of this work is to assess the tidal energy resource at the most promising areas for tidal current stream energy in this prefecture. With this aim, an FVCOM numerical model was validated with ADCP data measured in Naru Strait, Goto Islands. Monthly power density maps for the most promising locations are presented. Results show areas with considerable potential for tidal stream energy exploitation, as well as other areas with lighter conditions, enough for high-efficiency devices.
