This documents the GIS routing model for VIC model output. The GIS routing model is a diffusive transport approach for flow routing based on GIS flood modeling. The original concepts are described in Liu et al. (2003) and used in the WetSPA distributed hydrology model. Gavin Yang obtained the original code and ArcView setup scripts and modified them for use with the VIC model (Yang et al., 2011). More recently, Keith Cherkauer has built an ArcGIS toolbox for the preprocessing scripts eliminating the need to install older versions of ArcView. The routing model itself is still available in its original Fortran code, versions of which exist for routing both daily and 3-hourly output files. Development has begun on a more flexible version of the code in C that will read the VIC model output file header to find the runoff and baseflow columns, and accept the time step on the command line. As of the publication of this page, this code does not currently work.
