Maximum Periodic Wave Run‐up on Smooth Slopes

Abstract

Periodic wave run-up data on smooth structure slopes is reanalyzed in a unified format that allows maximum relative run-up to be estimated for coastal structures with slopes ranging from mild to steep. A method to predict the limiting wave relative run-up is proposed. The method has essentially two elements, a modified surf parameter, which allows consideration of steep structure slopes, and a limiting value of relative run-up, which provides a logical envelope for the run-up of nonbreaking waves. Considerable data are shown in a unified format, which gives a clear idea of the predictive ability of the method.
