Approximate Upper Limit of Irregular Wave Runup on Riprap.

Abstract

This report describes methods to calculate the approximate upper limit of runup on riprap revetments caused by irregular wave action. A formula to predict the maximum runup is developed from one laboratory study and compared to data from a second study. The formula is found to fit the data of both studies quite well. A slightly improved version of the formula is then developed by combining the data from both studies. The improved formula has little or no systematic error associated with structure slope, water depth, or wave conditions and is easy to use. Errors between predicted and observed elevations of the maximum runup had a root mean square value of approximately 12 percent. Keywords: Irregular waves; Prediction method; Revetments; Riprap; Runup.
