Estimating Nearshore Significant Wave Height for Irregular Waves

摘要

This report presents procedures developed by Goda (1975) for estimating nearshore significant wave heights for irregular wave conditions, using known offshore (deepwater) wave conditions and the nearshore bottom slope. Goda's methods represent an important increase in the engineering community's ability to predict waves propagating into shallow water. The method is based on a number of simplifications and empirical adjustments but appears to represent laboratory and limited field data reasonably well. It is suggested that the method be used; however, the results should be carefullyl evaluated to confirm that the method is not used outside of its range of applicability.
