海岸波浪の予知に関する研究(第1報) ―伊勢湾台風時における沖波の推算―

Abstract

Wave forecasting is one of the most important problems in coastal engineering at present.The problem of forecasting storm waves in deep water is, however, somewhat handicappedby lack of adequate data for storm winds and waves and by lag of the development of mechan-ical procedures of forecasting for moving fetches and variable wind vectors.In this paper, the graphical approach by Wilson in 1955 for moving fetches and variablewind vectors is discusse~l, and a modified new graphical approach is proposed.Both approaches are applied to the analysis of deep-water wind waves generated by Ise-Bay Typhoon.
