The coastal protection structures were constructed to shield a portion of the shore from beach erosion and seawater flooding. Anti-scour mat in front of a vertical wall is already present. These living structures decrease the erosion and physical damage that can often impose significant economic and environmental costs on coastal communities. Revetments are frequently constructed as permeable structures using natural stones or concrete blocks, strengthening wave energy absorption and reducing reflection and wave run-up. Coastal Structures are undergoing renewal and innovation to better serve the needs of our society from environmental co-existence and habitat enhancement to risk management. The shallow water that seawalls and dikes typically border also has the corresponding hydraulic loadings. Now customize the name of a clipboard to store your clips.
