Abstract

Green port structures (i.e. green infrastructure in ports and harbors) featuring habitats for marine organisms have been promoted in Japan as part of a comprehensive policy to reduce the environmental impact of ports and carry out habitat conservation, restoration, and creation. In this study, we evaluated the ecosystem services provided by green port structures in two highly urbanized bays (Tokyo Bay and Osaka Bay) in Japan. Our results show that the provision of some ecosystem services can be limited by circumstances particular to ports and other areas with restricted access. In the case of green port structures that have strong usage restrictions, for example, cultural services can only be provided if relevant authorities are prepared to conduct public events while ensuring participant safety. On the other hand, green port structures with weak usage restrictions are often equipped with incidental facilities such as parking lots and restrooms; these facilities can enhance the provision of cultural services (e.g. recreation and environmental education). Green port structures in highly urbanized bays often have usage restrictions, but their proximity to large populations means that they can potentially provide numerous ecosystem services. However, our study shows that appropriate management goals, such as protecting species and ensuring healthy habitats, are needed to maintain the value of these services in highly urbanized and eutrophic bays.

Abstract

The 2011 off the Pacific Coast of Tohoku Earthquake brought serious damage in the wide area in Japan. We must learn most of know ledge and findings from this unexpected giant earthquake disaster. It is said that the return period of the giant earthquake as the 2011 off the Pacific Coast of Tohoku Earthquake is the order of a thousand years....

Subjects
reaeration coeffcient, breakwater generating vertical circulation flow, substance transfer coefficient, reaeration capacity
Abstract

In summer seasons severe hypoxia or anoxia has been generated near the sea bottom in enclosed seas. In order to restrain the hypoxia and anoxia, authors have developed a new breakwater which generates vertical circulation flow. Hydraulic effectiveness of the developed breakwater has already been verified. In this study, reaeration characteristic of the developed breakwater is examined by laboratory experiment....
