analysis was used to develop the curves for K and K shown in Figure 29. 

 The equations used to compute the curves in Figure 26 explain about 82 percent 

 and 98 percent of the variance in K and K , respectively. Appendix B 

 gives the equations used in Figure 29 and other information related to the 

 regression analysis. The curves shown in Figure 29 fit the general trends of 

 the data quite well. However, the real value of Figure 29 is that it is a 

 compilation of information about wave transmission, wave reflection, and wave 

 energy dissipation of reef breakwaters. Figure 29 is an improvement over Fig- 

 ure 8 in Ahrens (1984) because Figure 29 is based on an analytic model; 

 whereas Figure 8 is based on subjective curve fitting to the observed data.
