Computer Model Library
Here's a list of Environmental/Hydrologic/Hydraulic/Water Quality/Water Resources computer models compiled and archived in the Civil & Environmental Engineering Department, Old Dominion University. All models are public domain, and has been compiled from various sources such as USEPA, USACE WES, USDA-ARS, etc. Most of programs are designed for DOS/Windows platform, and there're also several programs written and compiled for Unix platform. Please check the individual model for its system requirement and model assumption/limitation as well as source code availability before downloading. Once downloaded, please follow installation guide comes with the package. Most packages are in self-extractable form (i.e., *.exe) or compressed using the standard methods such as 'zip' (i.e., *.zip) or Unix 'tar'ed and 'gunzip'ed (i.e., *.tar.gz). If you do not have a de/compression utility readily installed in your computer, please download appropriate one from below. For 'tar'ed and 'gunzip'ed Unix files, please use
$ gzip -dc [file.tar.gz] | tar xvf -
to uncompress & restore original directories/files. If you do not have GNU 'gunzip' installed in your system, please download following GNU gzip program first, then uncompress the 'gunzip'ed and 'tar'ed model files.
