Maximum Periodic Wave Runup on Smooth Slopes

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