Companion software to ArcSWAT

SWATeditor reads the project database generated by ArcSWAT, allowing the user to edit swat input files, execute SWAT run, perform sensitivity, autocalibration and uncertainty analysis. This is a standalone program and does not require ArcGIS, thus helping users of ArcSWAT to share their project with others that do not have ArcGIS or much experience with GIS in general. In order to use the SWATeditor, the users need to have created an ArcSWAT project under the "write all" menu.
