Abstract
Third generation wave estimation models such as WAM and SWAN are used in practical operations such as wave designing and daily wave prediction. The study on the workability judgment of marine construction through WAM has been conducted and the authors have confirmed that there are cases in which during low wave season, the overestimation of wave height and underestimation of wave period were observed. It is attributable to the factor that energy is overestimated in high frequency region.
In order to improve the overestimation of energy on the high frequency region, we focused on the dissipation term of the energy source term and examined energy dissipation on the high frequency region. Although there are cases in which the wave height is underestimated during the high waves, it is confirmed that the accuracy of estimation can be improved at low waves. As a result, the accuracy of workability judgment of marine construction work made using WAM was improved.
