SWAT Water Yield 1973 Metadata (Subwatersheds)
Disclaimer: The data shown are not observed values or results from a calibrated
model. They are average annual values derived from an uncalibrated model (SWAT)
run through AGWA using all of its default inputs, and a distributed 12-year
precipitation record (1960-1972) from 7 gauges around the basin. These data are
provided for demonstration purposes only, and should not be used for scientific
analysis.

Title:
Description: Subwatersheds of the Upper San Pedro basin with percent difference
between results from two SWAT simulations run through AGWA: one
using the 1973 NALC landcover for model parameterization, and the
other using the 1997 NALC landcover.
