Summary

This tabular data set represents the percent of physiographic provinces compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "Physiographic divisions of the conterminous U. S." produced by the United States Geological Survey (Fenneman, 1946). Units are percent. The "Physical Divisions of the United States," is based on eight major 1946 divisions, 25 provinces, and 86 sections representing distinct areas having common topography, rock types and structure, [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) National Water-Quality Assessment Project (NAWQA) which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate the percent of physiographic provinces for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
