Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Hydrologic landscape regions (HLRs) in the United States were delineated by using geographic information system (GIS) tools and statistical methods including principal components and cluster analyses. The GIS and statistical analyses were applied to land-surface form, geologic texture (permeability of the soil and bedrock), and climate variables that describe the physical and climatic setting of 43,931 small (roughly 200 square kilometers) watersheds [...]

Purpose

The purpose of defining hydrologic landscape regions was to group watersheds in the United States according to their similarity in landscape and climate characteristics. The selected landscape and climate characteristics represent factors assumed to affect hydrologic processes in the environment. The hydrologic landscape regions grid was used to help design the sampling network in the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program.
