SPARROW, 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 empirically estimates the origin and fate of contaminants in river networks and quantifies uncertainties in model predictions.

Mississippi/Atchafalaya River Basins

Phosphorus Yield in the Mississippi River Basin

  SPARROW tracks nutrient delivery locally
  to the outlets of inland watersheds and
  regionally to coastal waters. Differences
  in the spatial patterns between the two
  maps illustrate the effects of phosphorus
  removal in streams and reservoirs on the
  quantities of phosphorus delivered locally
  to streams vs. those delivered regionally
  to the Gulf of Mexico from inland
  watersheds.[Read more about these
  and other SPARROW results]
