【 摘 要 】

This paper reports some of the results of a theoretical and experimental study of submerged, detached, segmented, trapezoidal rubble mound breakwaters. It focuses on the phenomenon of sea level set-up which occurs at these structures. A theoretical analysis is presented which gives an explanation for the occurrence of set-up and the experimental results so far confirm the proposed relationship, which is given by Equation 4. Various other checks are presented in the paper, such as a demonstration that the set-up can be eliminated by pumping out from behind the breakwater and the measurement of a net drift velocity offshore in the core of the breakwater.
