| Research Abstract |
Appearance of anoxia and hydrogen sulfide in dredged pits causing mortality of benthic animals is considered as one of the most serious water quality problems in polluted bays. Adverse impacts on marine environments in shallows and tidal flats due to upwelling of anoxic waters are also of great concern. In this study, we performed field measurements and numerical modeling of anoxia and hydrogen sulfide processes. Using the model, we elucidated the impacts of dredged pits on surrounding environments and developed an effective management methodology on the basis of application of water duct technology.
