Abstract: The experimental data on wave runup over rough slopes-both simple and composite are still quite limited. To obtain a better understanding of effect of slope roughness on the runups a series of tests are conducted on two simple slope models (1 on 1.5 and 1 on 2.0) and a composite slope model (1 on 1.5 with a berm). Regular incidence waves of varying height and periods are allowed to runup on the slopes. Artificial slope roughness (measured in terms of equivalent sand roughness) are simulated with three types of roughness elements: (i) rows of horizontal strips, (ii) rows of vertical strips, and (iii) symmetrical placing of 3-D blocks. The range of height of roughness element tested are 1.5 mm to 30.5 mm. The experimental results of the wave runup are compared with the available results of other investigators. The results are presented in the form of non-dimensional plots and discussed.
