Coastal protection of land reclamation areas is often composed of rock or otherwise permeable material. Wave-induced setup inside permeable structures can be a problem for land reclamation areas if the design land level is too low. Wave-induced setup has not been studied extensively. In this study we use COMFLOW, a numerical model based on the Navier-Stokes equations employing the Volume-Of-Fluid method to displace the free surface, to quantify wave-induced setup inside permeable structures. The results are summarized in a conceptual design formula to determine wave-induced setup as a function of wave height Hm0 and rock diameter Dn50.
