Abstract
The characteristics of tidal currents at the Oshima Strait were examined in relation to tidal current power generation using the data of direct current measurement and numerical simulation with FVCOM. We found the strong tidal currents with a maximum speed of 2 m/s in the eastern area of the strait. Moreover, it was shown from the output data of the simulation that the daily mean value of tidal power potential in the strong current area is about 170 MW.
