Wave Transmission 



Mooring load and amplified pressure signals for the largest 

 recorded event are shown in Figure 6. Dimensional analysis (Harms et 

 al . 1981) has shown that the transmission coefficient C^, where C^ 

 is the ratio of transmitted to incident wave heights (H^/H^-)* can be 

 expressed as 



[4] 



C^ = il;(L/B, H/L, D^/h, B/D^) 



For the La Salle Park FTB, B/Dt = 29.5 and D^/h = 0.085 at the 

 pressure transducer locations. Model tests of Goodyear FTB's (Harms and 

 Bender 1978) showed that wave transmission is insensitive to the B/D^ 

 parameter or the D^/h parameter for D^/h <^ 0.32. Values of 

 Hc/Lp were typically 0.04 to 0.08. 



Wave transmission results are given in terms of transmission 

 coefficients, C^(f), versus the ratio of wavelength, L(f), to 

 breakwater beam, B, where
