Abstract

 Tsunami-induced wave pressure and force acting on an instrumented specimen fronted by macroroughness elements are investigated numerically in terms of the arrangement of the macro-roughness elements. Numerical results show that the arrangement of the macro-roughness elements affects an increase rate of the inundation depth relative to the absence of the specimen, and accordingly exsisting formulae can underestimate the vertical distribution of the maximum wave pressure acting on the specimen. This suggests that it is essential to consider the arrangement of the macro-roughness elements when evaluating the wave pressure. Furthermore, it is found that the the change in the tsunami force acting on the specimen with the alongshore spacing of the macro-roughness elements constant can be evaluated by the momentum of the water mass in the absence of the specimen.
