Abstract:

A simple method for estimating wave height and period for fetch- and duration-limited conditions is developed from the field studies of Mitsuyasu and Hasselman. The velocity scaling is effectively based on friction velocity which allows incorporation of effects due to temperature stratification in the atmospheric boundary layer and variation in the coefficient of drag with wind speed. The method is the analytical equivalent of the growth relationship used in the US Army Corps of Engineers numerical wave prediction studies. It is intended for use in short fetch 200 km or less situations.
