Abstract
<p> Estimating of wave breaking point using 3D numerical calculations is important for wave-resistant design and for research on phenomena related to breaking wave. In this study, the transformation of breaking wave for three types of seabed slopes was calculated for different grid condition. The accuracy of the wave breaking point for each grid condition was verified by comparing them with breaker index and previous experiments. As a result, using a z-directional grid width that divides breaking wave height into approximately 20 divisions and a x-directional grid width approzimately 2 times the a z-directional grid width, breaker depth can be calculated with an error rate of ±20 % from breaker index. wave breaking points can be calculated with the same accuracy as in previous experiments. Therefore, we showed that wave breaking point can be evaluated with the same accuracy as the breaker index and previous experiment.</p>
