WAVE RUN-UP ON A SIMULATED BEACH

A.J. Sutherland, J.N. Sharma, O.H. Shemdin

Abstract


A set of experiments concerning wave run-up in the presence of an offshore bar is described. Results pertaining to the direct relationship between incident waves and run-up heights are presented. It is clear that in the majority of cases the offshore bar does reduce run-up heights. The experiments showed that under certain conditions very large run-up and rundown heights are produced. This is ascribed to a resonance effect between either the basin, formed between the bar and the beach, or the beach face and the incident waves.
