本研究首先利用Hughes(2004a)所提出之線性波浪溯升假設以分別計算光滑及階梯海堤斜面上波浪溯升之波浪動量通率參數，進而計算出其最大百分之二溯升高。其次，應用Schuttrumpf and Oumeraci(2005)於海堤波浪溯升及越波之研究中所提出的海堤堤面上波浪溯升水層厚度及流速之計算法以計算不同斜堤堤面條件下之波浪溯升厚度及流速。當波浪溯升厚度等於零時，其溯升所達到之最大高度與平均海平面之垂直距離即為溯升高。計算分析中可看出，最大百分之二溯升高與波浪動量通率參數間具有緊密之相關性，且修正後之波浪動量通率參數計算式可得較佳的波浪溯升高之預測結果。此外，在做水層厚度計算分析時如將捲波與湧波情況分開計算將可得較佳之相對溯升高與碎波相似參數間關係的計算結果。

This study first used the hypothesis of linear wave runup theory that proposed by Hughes (2004a) to calculate the wave momentum flux parameters of wave runup on smooth and stepped seawall respectively. After that the maximum two percent wave runup height can be estimated too. At the second, based on the computing method of wave runup lager thickness and it’s velocity that proposed by Schuttumpf and Oumeraci (2005), on their study of wave runup and overtopping, to compute the wave conditions. When the thickness of wave runup height becomes zero then the distance of wave climbing height to the mean water level was the wave runup height. From the result of analysis, we can see the correlation between the maximum two percent wave runup height and the wave momentum flux parameter was tightly. Meanwhile, the estimate equation that modified by this study for compute wave momentum flux parameter can obtained more accurate result if in the computation process to use the different condition of plunging and surging breaker individually.
