Hydrogeomorphic Regions of the Chesapeake Bay Watershed: HGMR
January 1, 2000
Generalized lithology (rock type) and physiography based on geologic formations were used to characterize hydrgeomorphic regions (HGMR) within the Chesapeake Bay watershed. These HGMRs were used in conjunction with existing data to assess the significance of ground-water discharge as a source of nitrate load to nontidal streams in the Chesapeake Bay watershed (Bachman and others, 1998). This work is part of the U.S. Geological Survey's (USGS) Chesapeake Bay initative to develop an understanding and provide scientific information for the restoration of the Chesapeake Bay and its watershed (Phillips and Caughron, 1997).
