Abstract
The Kurushima Straits is known as a sea area where the tidal current is very swift from old days, and is a dangerous place for the marine navigation. Power generation from tidal flow is noticed as one of the ocean energy utilization. In this research, abundance of the tidal current energy in the sea area around the Shimanami Sea Road including the Kurushima Straits was shown based on the 3-D numerical simulation result. We also indicated the representative sea area where suitable for the construction of the power generation facilities considering tidal current power map and submarine topography.
