Prediction of Overtopping Rates for Irregular Waves on Riprap Revetments
1992
Ward, Donald L.
Present methods of predicting wave overtopping on revetments are limited, and determining what data are available requires extensive interpolation and/or extrapolation of monochromatic wave conditions. Physical model tests were conducted to measure wave overtopping rates occurring on a 1:2 and 1:3.5 stone revetment slope. The tests cover a range of incident irregular wave conditions using a foreslope of 1:100. Results of the tests are expressed in terms of overtopping rate per length of structure versus relative freeboard. Relative fireboard is particularly effective, as it accounts for different water levels in the freeboard, wave heights in Hmo, and wave periods in Lo.
