Allen with radiation condition at the open boundaries. 



The solid line is computed by averaging water levels from 



every grid point in the Gulf at each time step. The 



dashed line is computed from the continuity equation. 



The datum is mean sea level 178 



109 Time sequences of the average water levels in the Gulf of 

 Mexico, 7?Q, obtained from the simulation of HUR5(L). The 

 solid line is computed by averaging water levels from 

 every grid point in the Gulf at each time step. The 

 dashed line is computed from the continuity equation. 



The datum is mean sea level 182 



110 Time sequences of the average water levels in the Gulf of 

 Mexico, tjq, obtained from the simulation of HUR23(L). 

 The solid line is computed by averaging water levels from 

 every grid point in the Gulf at each time step. The 

 dashed line is computed from the continuity equation.

111 Time sequence of the averaged water level in the Gulf of 

 Mexico, t}q, obtained from the simulation of hurricane 



Carla. The datum is mean sea level 184 



112 Dynamic peak surge, *, profile along shelf break obtained 

 from the simulation of HUR5 . Grid indicies are along the 

 bottom and the time of peak * is given by day and hour 



across the top. The datum is mean sea level 187 



113 Dynamic peak surge, *, profile along shelf break obtained 

 from the simulation of HUR23. Grid indicies are along 

 the bottom and the time of peak * is given by day and 



hour across the top. The datum is mean sea level 188 



114 Dynamic peak surge, *, profile along shelf break obtained 

 from the simulation of hurricane Carla. Grid indicies 

 are along the bottom and the time of peak * is given by 



day and hour across the top. The datum is mean sea level. 189
