STUDY ON HIGH-PRECISION WAVE CALCULATION METHOD FOR OKINAWA ISLANDS AND SAKISHIMA ISLANDS

Abstract

 The topographical features of Okinawa Islands and Sakishima Islands, it is typhoon-prone area and the coral reefs are well developed. Therefore, it is necessary to improve the accuracy of calculating the high wave and storm surges. In this study, as a method capable of calculating the wave height with high accuracy in the area, we have proposed a method of setting the wind field and air pressure field which is the external force conditions of storm surge forecasting and wave hindcasting. In addition, We make a selection of wave breaking model that allows the estimation of appropriate wave on the leaf terrain.
