    • Attributes for NHDPlus Version 2.1 Flowlines for the Conterminous United States: Bankfull Hydraulic Geometry Related to Physiographic Divisions

    Metadata Updated: January 20, 2026

    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).
