Prediction Method on "Recovery of Shoreline" effect in Ariake Bay

Abstract

Tidal flats in Ariake Bay were reclaimed from pre-Edo era to the post-WWII food shortage period for the main purpose of increasing farmland. In the process, high banks were constructed to protect farmland existing around the supratidal zone (shoreline). This, however, has led to the loss of waterfront or coastlines, as well as the ecosystem innate to the tidal flats, including the habitat of benthos and saltwater plants. This is thought to be one of the factors of the environmental deterioration of Ariake Bay. In this study, the prediction method of the benthos species and the biomass when the shoreline was artificially recovered was examined.
