SOLUTION SHEET FOR PROGRAM 104R-41CV 

 The following equations are given in the Shore Protection Manual: 



£b ^ 1 (2-91) 



H^, b - (aH^/gT^) 



a = 43.75(1 - e-15in) (2-92) 



b = '■'' 



(1 + e-1^-^"') (2-93) 



xp = TpHb = (4.0 - 9.25 m)Hb (7-3) 



Hb = ^-^■^— (7-4) 



Equation (7-4) can be rewritten in dimensionless form as: 



d^ 



Hb = 



[(b - ailb)-^ - mTpJ 



where 



Hb = Hb/gT2 and dg = dg/gT^ 



The above equation can then be solved via the quadratic formula for H^ in terms 

 of ds, Tp, m, a, and b where the positive root provides useful results. 



Hb = {(inTpb - ads - 1) + [(mTpb-ads-l)^ + 4amTp bdg] ^^ j_ (2ainTp)"-^ 

 This is the equation used in the program for design breaking wave height.
