Hydrogeomorphic Regions

Hydrogeomorphic Regions

This map was created by the USGS to demonstrate the hydrogeomorphic regions within the Chesapeake Bay. The underlying rock type and physiographic province influence the range of ground-water discharge values. These characteristics were used to divide the Chesapeake Bay watershed into eleven "hydrogeomorphic regions" or HGMRs. The characteristics of the rock type in each HGMR provide a surrogate for permeability and mineral composition of aquifers.
