Abstract: Abstract: Published and unpublished results of tests of monochromatic wave runup reanalyzed for both smooth and rough structure surfaces. The rough-surfaced structures included breakwaters and riprapped slopes, and both quarrystone and concrete armor units. Wave runup theory is discussed briefly and an empirical equation is given for runup on smooth slopes from waves which break on the structure slope. Example problems and methods of data analysis, together with general observations, are given. Smooth-slope runup results for both breaking and nonbreaking waves are presented in a set of curves similar to but revised from those in the Shore Protection Manual (SPM) (U.S. Army, Corps of Engineers, Coastal Engineering Research Center, 1977). The curves are for structure slopes fronted by horizontal and 1 on 10 bottom slopes. The range of values was extended to; relative depth is important even for waves which do not break on the structure slope. Rough-slope results are presented in similar curves if sufficient data were available. Otherwise, results are given as values of r, which is the ratio of rough-slope runup to smooth-slope runup. Scale-effect in runup is discussed .
