Seagrass wrack and coastal structures: lessons from south-western Australia

Research output: Chapter in Book/Conference paperConference paperpeer-review


Coastal infrastructure projects such harbours and marinas usually require the construction of breakwaters to maintain a stable entrance channel but they also interrupt the alongshore transport of sand resulting in accumulation of sand on the upstream section. In south-west Australia due to the presence of large offshore seagrass beds, wrack (dead seagrass leaves) accumulation has become a major environmental problem leading to the development mitigation options. In this paper, we present results from two contrasting locations as case studies: Port Geographe and Jurien Bay. Problems associated with seagrass wrack, a common feature in many tropical and subtropical regions are presented. Solutions to alleviate this problem through the development of a seagrass wrack transport model coupled to a morphological model are described.
