The Field experiment of the artificial tidal flat with the reused dredged soil in Kyusyu sea area

Abstract

As a part of MLIT's efforts for "Restoration and construction of tidal flats by reused dredged soil", an experimental tidal flat had been created in Kyushu sea area for developing the utility of the dredged soil. In order to evaluate and verify the improvement effect on the environment, we carried out monitoring research on the habitat environment, habitat situation and the condition of the sea area at 3 sites - Port of Miike, Port of Ooura, and Port of Nakatsu. As a result, environment improvement in the sea bottom was observed in the artificial tidal flat with reused dredged soil, and it was confirmed that such artificial environment served as a suitable habitat for marketable species and the diversity of benthos.
