The impact of the collision resulted in the dissipation of a part of the wave 

 energy. The effect of relative breakwater width, L/W, on wave energy trans- 

 mission is shown in Figure 207. The transmission coefficient was less than 

 0.40 when the wavelength was less than 55 feet (the maximum design wavelength 

 to be expected in reservoirs is 65 feet). when the wavelength was increased 

 to 95 feet, the resulting transmission coefficients ranged from 0.45 to 0.65.
