Watershed Description:1270 km^2 Gumera located in the headwaters of the Blue Nile in Ethiopia and 37 km^2 Town Brook in the Catskill Mountains of New York. Runoff in both watersheds is primarily generated via saturation-excess processes (i.e.; variable source areas - VSA hydrology). 
Calibration Summary: 
Validation Summary: 
General Comments:This paper presents a simple way to use SWAT's existing soil-water calculations in order to model saturation-excess runoff with out relying upon the Curve Number methodology. Implementing this water balance method for calculating surface runoff returned more accurate results for a data-scarce watershed in Ethiopia than the Curve Number based SWAT. In the Catskills, the water balance returned results equal to the Curve Number, but with a physically based approach. This resulted in more accurate spatial distribution of runoff generating areas throughout the watershed.
