. Characteristics of reef breakwaters. Breakwaters; Ocean waves; Water waves. (14) where C = and C = are coefficients. Equation 14 explains about 80 percent of the variance in K for the 204 tests considered, follows r r the trend of the data well, and approaches the correct limiting REEF WAVE REFLECTION PARAMETER, -—— ATds Figure 25. Wave reflection coefficient versus the reef reflection parameter illustrating the ability of Equation 14 to predict reflection, all subsets 38. While the analysis was being conducted to develop Equation 14, it was clear a relation could be developed which could explain considerably more of the variance in K if more dependent variables were used. Better esti- mates of reflection from reefs would be valuable since wave reflection causes navigation problems, increases potential for toe scour, and can cause erosion at nearby shorelines by increasing the severity of wave conditions. In addi- tion, knowledge of wave reflection provides a way to estimate the amount of wave energy dissipated by the reef. The ability of low and submerged rubble structures to dissipate wave energy has long been appreciated, but only in 37.
