Data were obtained which indicated that power requirements are function of jet area, jet submergence, attenuation, and wave characteristics. It was concluded that no serious scale effect was obtained over the 1:4.5 scale ratio of the tests. Tests of multiple-manifold systems and the effect of waves striking the breakwater at an angle were limited in scope, but data were obtained providing an indication of the effect of these variables.en-USReport
