where A is the area of a closed region R in the x,y plane 

 whose mapped image is R* . 



The kinematic wind-stress components t~* and t™* are re- 

 lated to their x,y component counterparts (t , t ) at a given 

 point by: ^

The relation between the wind stress and windspeed is:

 x = K W 10 , K = -£ C (50) 



P W 



where p^ is the air density, pw is the water density, Cr> is a 



nondimensional drag coefficient, and W^q is the windspeed at an 



elevation of 10 meters above the water surface. The value of K 

 (Reid and Bodine, 1968) is taken as: 



Ki , if W l0 £ 7.0 m-s -1 



K = _! 



Kj + [l.O - 7.0/W 10 ] 2 K 2 , if W 10 > 7.0 m-s 



where Ki is 1.1 x 10 -6 and K 2 is 2.5 x 10" 6 . 



The values of K x and K 2 used by Whitaker, Reid, and Vastano 

 (1973) for Lake Okeechobee were found to be too large for the shelf 

 surge computations investigated in this study.
