K = r/50 . 



Figure 19 shows the adopted inflow angle profile. This radially 

 varying inflow angle was applied only from the begining of the 

 simulation to 0000 GMT 10 September. A constant inflow angle was 

 resumed after this period since there was no other evidence of 

 negative inflow angles on the remaining available surface charts. 



Results of the simulation were sampled every 24 hour prototype 

 time. These included digital fields and map plots of the height 

 anomalies and currents for both modes, and surface currents whose 

 values were retrieved from the modal currents. At the end of the 

 simulation, the computed and observed hydrographs at the tide 

 stations were plotted. Contours of the peak surge on the continental 

 shelf for the entire Gulf of Mexico and for the Texas-Louisiana shelf 

 were also plotted. 



5. Results of Car la simulation 



Figures 20 through 28 show the computed (solid) and recorded 

 (dashed) hydrographs at the stations used in this study. The overall 

 comparisons are fair, especially during the first half of the 

 simulation period. There is not much activity in the southwestern 

 portion of the Gulf (Campeche Bay) as revealed from the hydrographs 

 from the three Mexican stations (Figs. 26 through 28). The simulated 

 hydrograph at Key West has a slow oscillation with a period of 

 approximately 7 days. The mean of this long period oscillation lies 

 close to the meain of the recorded water level. This signal is also 

 observable in the St. Petersburg computed hydrograph. However, the
