Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 04:13 AM | Dataset Last Updated: March 26, 2026 at 12:00 AM
This tabular data set contains information on bankfull depth, width and cross-sectional area for each NHDPlus version 2.1 data suite (NHDPlusv2) flowline (Moore and Dewald, 2016) for the conterminous United States. These data were created using regional regression equations outlined in Bieger and others (2015). The equations predict bankfull width, depth and cross-sectional area as a function of drainage area for eight Physiographic Divisions of the conterminous United States (Fenneman, 1946).
