APPLICATION OF FETCH AREA METHOD IN MONSOON WAVE HINDCASTING

Abstract

The Fetch Area Method ( FAM ) derived from Elementary Wave Model is used to analyze the winter monsoon wave of Taichung Harbour. The empirical wind-wave energy transfer coefficient f determined by FAM for this area is 7.25 x 10~ A relationship between g T , /2TTU and g t'/u is also found, where U is the average wind speed and t* the duration. A comparision of the wave hindcasting of FAM has shown that the latter is better than the former, and the former is valid only as the wind velocity increases, once the wind decreases the SMB Method is no more valid.
