^zs = -Te — ^gb ^^" ^"z? (A-6) 



where C^^ equals group wave celerity equals (g d^j)^''^ linear wave theory; 

 therefore 



P^s=^"-(|y'' (gH,)l/2sin2a^ (A-7) 



(g) Using equation (A-2), (A-5) , and (A-7) and assuming m = d^/W 



_ pgHz, W V C/ 



(h) The value of (V/Vo) can be assumed equal to that given by Longuet- 

 Higgins (1970) 



(i) The value of V is measured using LEO technique 



V - V^EO (A- 10) 



(j) Equation (A- 8) now becomes
