Integration of FEST-C (EPIC/WRF/CMAQ) and SWAT: EPIC was used to simulate agricultural land because of its complexity in simulating agricultural production and related pollutant loadings, as well as its interaction with CMAQ and WRF. HAWQS-SWAT simulates non-agricultural land and takes in FEST-C output from agricultural land at an outlet of a subwatershed, then simulates stream and channel processes, and routes combined loadings to the outlet.
