| Research Abstract |
The objectives of this project are to investigate in details the environmental properties of flow, water quality and seabed quality in Isahaya Bay before opening the north and south gates of Isahaya reclamation dike and to accumulate significant and useful data to reveal the change in environments after opening the gates as benchmark data.The obtained main results are as follows.1)The environmental properties of seabed quality in Isahaya Bay become worse toward the inner area of bay from the bay mouth and the deterioration rate also increases toward the inner area of bay.2)The salinity stratification is formed over the whole region of Isahaya Bay in the rainy season and it is mainly due to the discharge from Chikugo River.3)The hypoxic water mass tends to be generated off Konagai and become large over the whole region of Isahaya Bay.
