The Variable Infiltration Capacity (VIC) model is a macroscale
hydrologic model that solves full water and energy balances, originally
developed by Xu Liang at the University of Washington (UW).
The version of VIC source code used is of 5.0.1 on < https://github.com/UW-Hydro/VIC/>,
see Hamman et al. (2018).
Development and maintenance of the current official version
of the VIC model at present is led by the UW Hydro (Computational Hydrology
group) in the Department of Civil and Environmental Engineering at UW. 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. If you make use of
this model, please acknowledge the appropriate references listed in the help
page of this package or on the references page
of the VIC official documentation website.

VICmodel is an R implementation of the Variable Infiltration Capacity (VIC) macroscale distributed hydrologic model (Liang et al., 1994) originally developed by Xu Liang at the University of Washington (UW), USA, and currently the model is maintained by the Computational Hydrology group (UW Hydro) in the Department of Civil and Environmental Engineering at UW. This R package is developed by Ruida Zhong et al. at the Center for Water Resources and Environment, Sun Yat-sen University (SYSU). This package is built based on the VIC source code V5.0.1 (Hamman et al., 2018), aim to for the more convinient use for the R users and other users or researchers using windows platform.
The VIC model can simulate several land surface processes physically based on both water balance and energy balance, e.g. Evapotranspiration (on vegetation canopy, vegetation transpiration and soil evaporation), runoff (surface and underground), changes of soil moisture, soil ice and soil temperature of each soil layer, accumulation and melt of snow, sensible and latent heat flux between atmosphere and land surface, streamflow of the basin outlet (needed to be coupled with a runoff routing model), and many other variables. The landsurface parameters (about vegetation, soil, topography) and the timeseries of meteorological data (meteorological forcing, including precipitation, air temperature, incomming shortwave and longwave radiation, wind speed, air pressure and vapor pressure) are necessary inputs to run the VIC model.

This is an example to run the VIC model using the sample inputs:
#Sample data, with 16 gridcells and 10 day hourly meteorological forcing inputsdata(STEHE)forcing <- STEHE$forcingsoil <- STEHE$soilveg <- STEHE$veg# Options and settings of the VIC modelvic_param('start_year', 1949)vic_param('start_month', 1)vic_param('start_day', 1)vic_param('end_year', 1949)vic_param('end_month', 1)vic_param('end_day', 10)vic_param('step_per_day', 24)vic_param('snow_step_per_day', 24)vic_param('runoff_step_per_day', 24)# Definition of model outputs (output variables, timescale, etc.)out_info <- list(wb = list(timescale = 'hour', aggpar = 6,outvars = c('OUT_RUNOFF', 'OUT_BASEFLOW', 'OUT_SOIL_MOIST'),aggtypes = c('sum', 'sum', 'end')),eb = list(timescale = 'day', aggpar = 1,outvars = c('OUT_SWE', 'OUT_SOIL_TEMP'),aggtypes = c('avg', 'min')))# Run the VIC modeloutputs <- vic(forcing, soil, veg, output_info = out_info)# Show information of model run and outputs.print(outputs)
Fix some codes with bug or potential problem of the VIC source codes.
Fix the data error of the
STEHE sample data.
Add the observed streamflow data to
STEHE sample data for routing model.
