For general information, see the ADCIRC site, ADCIRC FAQ, or the ADCIRC Wikipedia page. For model documentation not yet available on the wiki, see the ADCIRC site. New content is being continuously added to the ADCIRCWiki, and material from the main ADCIRC site will be gradually transitioned over to the wiki.
If the time varying bathymetry feature of ADCIRC has been activated, the fort.76 output file will be produced according to the output control specifications for full domain time varying water surface elevation output (NOUTGE, etc) as specified in the fort.15 file.
See fort.76 file format for details.
