碩士 / 國立臺灣海洋大學 / 河海工程學系 / 95 / The purpose of this study is to investigate the characteristic of wave dissipation structure on steep coast by experimental study. The experiments consist of 11 different conditions of incident waves, two for the slope of the revetment and three kinds of armor unit with a fixed or a movable bed. Wave runup on the revetment, the offshore position of the breaker and the scouring depth at the break were measured for further analysis. Experimental results show that the height of wave runup on the revetment decreases as increasing relative water depth or wave steepness. The more layers of armor unit on the revetment with steep slope S=1/2, the lower height of wave runup can be found. Therefore, the effect of wave dissipation will more significant while the more layers of armor unit on the revetment. The offshore position of the breaker is closer to the shore as the incident wave period increases.
