本研究主要為探討光滑及階梯海堤上波浪越波與波浪動量通率參數、波浪溯升水層厚度與波浪溯升水層流速等之關係。研究方法為利用試驗在各種不同海堤堤面及入射波高條件下，分析其在不同的堤頂出水高及堤面坡度的情況下對波浪越波所產生的影響。在數值計算方面，應用動量通率溯升理論(Hughes, 2004)及溯升水層厚度和流速(Schuttrumpf and Oumeraci,2005)計算式以計算波浪越波量，同時探討相對越波量和相對堤頂出水高間之相關性。研究結果顯示波浪越波量與堤頂出水高間關係甚為密切。同時，階梯堤具降低波浪越波量之效應亦甚為顯著。

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.
