Abstract
Regional Application of NHDPlus for NAWQA SPARROW Modeling
Track: Water Resources
Author(s): Richard Moore, Craig Johnston
SPARROW (Spatially Referenced Regressions on Watershed Attributes) models are being developed by the National Water Quality Assessment program of the U.S. Geological Survey for large geographical regions, referred to as 'major river basins'(MRB), that cover the contiguous United States.
The National Hydrologic Dataset Plus (NHDPlus) will serve as the hydrologic framework for 2 of the MRB SPARROW models - the Northeast Atlantic Seaboard (New England through Chesapeake Bay) and the entire Southeastern United States (areas east of the Mississippi River Basin that drain to the Atlantic Ocean and Gulf of Mexico). One of the most valuable benefits of NHDPlus, for water-quality modeling, is the rich set of attributes that have been developed. NHDPlus is an improved 1:100,000-scale National Hydrography Dataset that includes a set of value added attributes for stream network navigation, a National Seamless Database of topographically derived catchments, and estimates of mean annual stream flow and velocity.
