碩士 / 建國科技大學 / 土木與防災研究所 / 99 / This research mainly study the relationship between wave overtopping and wave momentum flux parameter, wave runup layer thicknesses and it is veloctities at smooth and step dikes was completed too. The method of research is using kinds of different slope dikes and incident wave as model test conditions to analysis the influence of free board of dike to wave overtopping rate. As to the numerical calculation, the theory of wave momentum flux to wave runup height (Hughes, 2004) and the theory of wave runup thickness as well the wave runup velocity to estimate the wave overtopping rate was applied. Meanwhile, the correlation between the free board of dike and the wave overtopping rate was study too. Result shows the influence of dike free board to wave overtopping rate was enormous. Also, the effect of step on sloping dike to reduce the wave runup height as well the wave overtopping rate was enormous too.
