Study on Selection for Zostera marina Beds Using Numerical Model

摘要

Recently, fishery products have been decreased in the Seto Inland Sealocated at the western part of Japan. One of these reasons is decrease ofseagrass and seaweed beds such as Zostera marina, Sargassum and soon. The valuable marine resources are using Zostera marina beds asspawning and nursery grounds. In this study, the authors reproducedthe flow field around the Zostera marina bed behind the detachedbreakwater using three-dimensional hydrodynamical model. Then weexamined the appropriate area of Zostera marina beds and newconstruction method of detached breakwaters for preservation ofseagrass and seaweed beds.
