MODEL DESCRIPTION
A method for regional interpretation of water-quality
monitoring data
Stream nitrogen yield (kg/km2/yr) for conterminous U.S. watersheds
SPARROW relates in-stream water-quality measurements to spatially referenced
characteristics of watersheds, including contaminant sources and factors
influencing terrestrial and stream transport.
The model empirically estimates the origin and fate of contaminants in streams, and quantifies uncertainties in these estimates based on model coefficient error and unexplained variability in the observed data.
