Abstract

 This study focuses on behavior of coral gravels under forward leaning waves around the surf and swash zones. We first carried out laboratory experiments in which waves and moving gravels were captured through the analysis of video images recorded from the side of the flume. It was found through comparisons of these time-varying quantities of water surface fluctuations and velocities of moving gravels and surrounding currents that the acceleration of near-bottom fluid and associated bed slopes appear to have significant influence on movement of coral gravels.
