Wave forces acting on the triangular roughness elements are experimentally investigated in 2-dimensional wave flume. The roughness elements are models of ridges of the unconsolidated washboard-like rocky sea bottom surface comprised of an alteration of geosynclinal strata. Horizontal wave forces acting on the elements are mainly composed of drag and inertia forces. The drag force is the prominent force component. Vortices separated from the roughness elements cause the drag forces. They are influenced by the shape of roughness elements and the distribution distance between adjacent roughness elements. Vertical forces consist of the drag, inertia and lift forces and hydrostatic pressure variation-caused forces, which are complicatedly mixed.
