The investigtion was conducted primarily to determine the effect of side slope angle and structure porosity on wave run-up, and to investigate the effect of wave steepness HL and relative depth dL. The experimental equipment consisted of a glass-walled wave channel, 60-ft long, with a wave generator at 1 end and a model structure at the other end. The permeable structure was assembled so as to prevent natural equilibrium condition on the side slope for the full range of angles investigated 15 to 90 deg. Results of tests indicate that structure porosity has a major effect upon wave run-up the critical point of slope angle appears to be about 30 deg. Any variation from this point will probably decrease wave run-up, other things being equal. For increasing values of HL 0.03 there is an increase in wave run-up, and for decreasing values of dL there is an increase in wave run-up.
