摘要：Experimental investigations of coastal erosion generated by the action of irregular waves were carried out in laboratory flumes. It is well known that both the field surveys and the experimental studies are not precise enough to give details about the suspended sediment load due to wave action. In this study, different wave groups were generated over the beach profile and the amount of coastal erosion were measured using terrestrial laser scanner. Then obtained results were compared with the results gathered by means of conventional instruments. It was concluded that comparing to the conventional methods, laser scanners can be effectively used to define the beach profile changes under wave actions.
