 simulated water levels from the indicated station. 



The maximum surges generated by HUR2 and HUR3 imply a direct 

 relationship between peak surge at the open coast and forward speed 

 of the storm. Jelesnianski (1972) proposed a correction factor for 

 the effect of storm vector motion (track direction and forward speed 

 at landfall) which is larger for a faster moving storm provided that 

 the landfall angles are the same. 



Figures 64 and 65 show the simulated hydrographs at Galveston 

 from the HUR2 and HUR3 simulations, respectively. The initial rise 

 of water level before the peak surges are present in both runs which 

 are concurrent with the first maximum of their corresponding tjq 

 signals. The maximum peaks and periods of tjq as determined from 

 Figs. 66 and 67 are 0.22 m, 28 h and 0.21 m 30 h, respectively. The 

 time lag, 6q, is approximately 17 h for the faster storm (HUR2) and 

 about 24 h for the slower storm (HUR3). 



The maximum surges produced by storms of large Rju^x 

 (HUR4,HUR5,HUR6) are on the order of 2 m larger than those 

 corresponding to the small storm (HUR1,HUR2,HUR3) simulations. 

 Except for a larger percentage of increase in the peak surge at the 

 open coast, the results are in qualitative agreement with 

 Jelesnianski (1972) in which a very simple bathymetry was employed. 



The hydrograph at Galveston from the HIJR4 simulation is shown in 

 Fig. 68. The time of the peak surge and the time at which the 

 initial rise of water level reaches the maximum are exactly the same 

 as in the HURl simulation. The resurgence oscillation is concealed
