Abstract
Submerged breakwater and artificial reef structures are a widely used coastal defense measure to protect shorelines. A new type of concrete block has been designed for the construction of artificial reef structures. To determine the effectiveness of the designed blocks in reef and breakwater construction, large-scale hydraulic experiments were performed in conjunction with numerical simulations utilizing CADMAS-SURF, a numerical wave flume easily applied to the study of complex interactions between waves and submerged artificial reef structures. This study examines the key properties, such as wave reflection, transmission, and setup/setdown, to demonstrate the advantages of the new type of concrete reef structure in comparison to typical low- or medium-porous rubble mound structures currently used in the field.
