SUBROUTINE METER Calculates and saves the vertically averaged 

 water velocities at prescribed grid locations 

 for output at program completion. 



SUBROUTINE HUV Outputs the saved information of the simu- 

 lated hydrographSj simulated current meters, 

 and observed water levels at program completion. 



3. Type of Computer. 



The program SSURGE may be run on any computer with minimum 

 core requirements of approximately 30K words of memory (based on 

 the present sample program appropriate to the Hurricane Carla 

 surge simulation) . The program has been executed successfully on 

 the IBM 360, CDC/6600 and 7600, and GE/635. The present sample 

 program requires no auxiliary storage devices, peripheral devices 

 or magnetic tape input or output. No site-dependent computer 

 plot routines are involved in the program. Approximately 14.4 

 minutes of machine time on a GE/635 is required for the sample 

 program to complete 66 hours of surge simulation. 



4. Input Data. 



Input data, other than constants defined in MAIN, are read 

 in SUBROUTINE FIELD. These data are on cards prepared according 

 to the following list. 



(1) Card 1 



NTl - Number of cards (max. 50) containing on each TIM, ROT, 

 RAD, VRMAX and PZRO (format 15). 



(2) Card Group 2 



NTl cards with each card containing values of 



a) TIM The time in hours at which the hurricane wind 



and atmospheric pressure parameters are 

 recorded (format FlO.l). 



b) ROT The angle in degrees between the direction the 



storm is moving and the region of maximum winds 

 (format FlO.l) . 



c) RAD The distance in nautical miles from the storm 



center to the region of maximum winds 

 (format FlO.l).
