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

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).

Attributes for NHDPlus Version 2.1 Flowlines for the Conterminous United States: Mean Flow Path Distance to NHDPlus Version 2.1 Streams

This dataset describes mean flow path distance, in meters, to flowlines from every NHDPlus version 2.1 (NHDv2) flowline in every catchment. A National flow distance raster utilizes NHDPlus Version 2.1 flow direction rasters to compute a national flow path distance raster. For the purposes of this dataset, NHDPlus Version 2 catchments were overlaid to compute a mean flow path distance to flowline for each flowline catchment.
