SHORL 



291. The input file SHORL.DAT holds the position of the initial shore- 

 line, i.e., the shoreline used by GENESIS at the start of calculation. In a 

 typical project, there will be at least three SHORL files, one each for the 

 calibration, the verification, and the project to be designed (present-day 

 shoreline position) . Positions of the shoreline are given in the units 

 selected at Line A. 2 of the START file and are measured from the baseline 

 (x-axis). A shoreline position must be given for each grid cell; i.e., there 

 must be NN calculation cells as entered at Line A. 3 in the START file. An 

 example of a SHORL file is given in Figure 24. 



292. If the modeler specifies at Line A. 4 in the START file that only a 

 portion of the shoreline will be used in the simulation, then only that 

 segment of the shoreline between and including the boundary cells is loaded 

 from SHORL. However . shoreline positions must be given for the full range of 

 the calculation grid (NN points), as GENESIS will load positions of the 

 shoreline subsection with reference to the original, full grid. 



293. Shoreline positions may be entered in "free format," i.e., with or 

 without a decimal. Individual entries must be separated by either a blank 

 space or a comma (or both) and placed in ascending order of grid cell number. 

 Exactly ten entries must be placed on each line, except for the last line .
