SPAtially Referenced Regressions On Watershed Attributes (SPARROW) Modeling of Surface-Water Quality
 Entry ID: 01-usgs_sparrow-01

[ Update this Record ]

Summary
Abstract: The SPARROW method uses spatially referenced regressions of contaminant
transport on watershed attributes to support regional water-quality assessment
goals, including descriptions of spatial and temporal patterns in water quality
and identification of the factors and processes that influence those
conditions. The method is designed to reduce the problems of data
interpretation caused by sparse ... View entire text
