Detailed Description

Interview by Richard Coupe (U.S. Geological Survey) of Richard Rebich-- a scientist involved in the National Water Quality Assessment (NAWQA) Study of Agricultural Chemical Transport (ACT)-- results of SPARROW Modeling. SPARROW is a a modeling tool for the regional interpretation of water-quality monitoring data. The model relates in-stream water-quality measurements to spatially referenced characteristics of watersheds, including contaminant sources and factors influencing terrestrial and aquatic transport. SPARROW estimates the origin and fate of contaminants in river networks and quantifies uncertainties in model predictions.
