Abstract
<p> There is concern about the risk of inundation caused by wave overtopping and surge overflow due to storm surge, and the countermeasures for the risk is an important issue. The authors focused on an impermeable double parapet seawall as a countermeasure against storm surge flooding, and proposed an estimation equation to calculate the wave overtopping discharge through the double parapet seawall based on the hydraulic experiments for regular waves. In this study, the estimation equation was partially modified, and validated for irregular waves according to the results of hydraulic experiments under irregular waves. Moreover, numerical experiments were conducted using OpenFOAM to confirm the applicability of the estimation equation on a wide range of conditions. The results of the numerical experiments agreed with the hydraulic experiments in terms of qualitative characteristics, however, there was a tendency to underestimate the quantity of wave overtopping compared to the hydraulic experimental results.</p>
