From Equation [27] we define the following nondimensional pitch response 

 parameter: 



Kh 9 



KA e TH - 0) (1 + I') 



where we assume €,„ = 0. This parameter is the ratio of pitch angle to 



Lb 



the maximum wave slope at the depth h. Using the relation for the wave-

 length A = 2TTg/a) , it follows that 



|e| 2C^^ Xpg ¥ 



Kh 



KA e T£ A - 2Trg (I + I') 



or, from the above data, and with A in feet, 



I el 14.5 A

A dimensional measure of pitch response is

 Where Ae is the effective wave height at the depth h. Thus for the
