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 globally. Development and maintenance of the current official version of the VIC model is led by the UW Hydro | Computational Hydrology group in the Department of Civil and Environmental Engineering at the University of Washington. Every new application addresses new problems and conditions that 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 development project, which means that contributions are welcome, including to the VIC documentation.
