For a 2DDI ADCIRC run that does not use NetCDF, the file ends here. For any ADCIRC run that uses NetCDF, the lines NCPROJ through NCDATE (described at the end of this file format) are required metadata and must be added at the end of the fort.15 file.

The following information is only included for a 3D run:

for k=1 to NFEN (include this loop only if IGC = 0, k=1 at bottom, k= NFEN at surface)

end k loop

for k=1 to NFEN (include this loop only if IEVC = 0, k=1 at bottom, k= NFEN at surface)
