Program Description, Equations, Variables, etc 



This algorithm computes wavelength, L, in water depth, d, given the wave 

 period, T. The program then computes wave transmission over a thin ver- 

 tical barrier in water depth, d, using Fuchs' equation: 





4ird , . , 4iTd 



— — + sinh — — 



4TTd . J , 4Trd 



— I — + sinh — — 



where Ht is the transmitted wave height. Hi the incident wave height, and 

 h the height of barrier. Note that this equation cannot be used when wave 

 transmission is by overtopping of a structure. Algorithm uses English or 

 metric system of units.
