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
