Wave Reflection and Transmission at Permeable Breakwaters,
Abstract
Rubble mound breakwaters are designed to protect exposed marine areas from excessive wave activity. Observations of breakwaters inter-acting with surface waves in laboratory models and in full-scale field applications demonstrate that significant wave energy is transmitted through the interstices of structures commonly regarded as impervious. The objective of this investigation is the development of a theoretical analysis to account for this phenomenon. Three breakwater configurations are considered: (1) crib style breakwaters with vertical walls and homogeneous fill, (2) conventional trapezoidal shape breakwaters with layered fill, and (3) pile array breakwaters composed of vertical piles placed in symmetric patterns. The two dimensional problem is studied. Waves are assumed to arrive at normal incidence. (Author)
