Regional Hydraulic Geometry Curves are log-log
plots comparing channel dimensions (top width, mean depth, and cross-sectional
area) at 'bankfull' or effective discharge (usually between the 1.1 and 1.9 year
return interval) versus drainage area.
The National Water Management Center (NWMC) is working with other Federal,
State, and Local agencies to develop Regional Hydraulic Geometry Curves across
the country. We are organizing data by Physiographic Provinces (see map below).
