Technical Abstract: Autocalibration of a water quality model such as SWAT (Soil and Water Assessment Tool) can be a powerful, labor-saving tool. When multi-gage or multi-pollutant calibration is desired, autocalibration is essential because the time involved in manual calibration becomes prohibitive. The ArcSWAT Interface provides accessibility to the Sensitivity Analysis and Parameter Autocalibration component of SWAT for single gage or single pollutant calibrations. This manuscript walks a user through the process of using the interface and provides guidance for accessing the portions of the Autocalibration component not available in the interface.
