Abstract
The objective of this study is to verify the possibility of restraining the formation of low dissolved oxygen water condition in the bottom layer of semi-enclosed bay by tidal current control. Firstly, Omaehama area in Osaka Bay was selected for case study area and detailed environmental investigation was conducted in order to clarify how limited tidal current affected the water quality in the region. Secondly, the feasibility of tidal current control as water quality remediation measures was studied by hydraulic simulation. As a result of this study, it was confirmed that anoxic water condition in semi-enclosed bay could be reduced by tidal current control by enhancing water exchange between the semi-closed area and outer sea and reducing the amount of organic suspended solids.
