Program Description, Equations, Variables, etc. 



This program calculates the product of the wave number and depth, kd , the 

 ratio of group wave speed to wave celerity, n = 0.5 (l+2kd/sinh 2kd) , the 

 group wave speed, €g, the shoaling coefficient. Kg, the refraction coeffi- 

 cient, Kj-, horizontal orbital velocity, u, and vertical orbital velocity, w 



Program input includes wave period, T, deepwater wave angle, aQ , deepwater 

 wave height, Hq, wave phase angle, 6, depth of water, d, at which results 

 are desired, and depth from surface, z, at which velocities are calculated. 

 This program assumes straight and parallel offshore bottom contours for 

 assum.ption of Snell's law of refraction. Algorithm uses English or metric 

 system of units.
