Attempt for Accuracy Improvement of Wave Hindcasting in Inland Sea

Abstract

Recently, the third generation wave models are widely employed in many countries. However, the examination of their estimation accuracy in an inland sea is not necessarily sufficient due to insufficient wave observation data and difficulty of estimating accurate wind field around the area In this paper, therefore, we applied a modified WAM to Seto Inland Sea with the wind data estimated for Typhoon 0514 with MM5 and Typhoon Bogus. The estimation accuracy of wind and waves were investigated with the data observed at a few stations. Several energy source functions that had been proposed so far were examined in the modified WAM. In addition, ADWAM (Adjoint WAM) was also applied for the data and its applicability and usefulness were discussed.
