The VIC Model

VIC (Liang et al., 1994) is a macroscale hydrologic model that solves full water and energy balances, originally developed by Xu Liang at the University of Washington. VIC is a research model and in its various forms it has been applied to most of the major river basins around the world, as well as being applied globally. The VIC model is distributed under the GNU GPL v2.0 license. If you make use of this model, please acknowledge the appropriate references listed on the references page.

Development and maintenance of the current official version of the VIC model is conducted at the University of Washington, Department of Civil and Environmental Engineering, under the direction of Bart Nijssen. Every new application addresses new problems and conditions which the model may not currently be able to handle, and as such the model is always under development.  The VIC model is an open source develment project, contributions from outside the University of Washington Land Surface Hydrology Group are welcome. Archived, current, beta, and development versions of the model are available via the group's GitHub repository.
