Attributes for NHDPlus version 2.1 catchments and modified routing of upstream watersheds for the conterminous United States: Combination of landuse and geology.

This tabular data represents the area of combined landuse and surficial materials for the conterminous United States linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data are the National Land Cover Dataset (NLCD) representing 2011 ground conditions (Homer, 2013) , and the "Map database for surficial materials in the conterminous United States" produced by the United States Geological Survey (USGS Soller and others, 2009). Surficial materials are defined as an unconsolidated blanket of sediments in which soils commonly are developed. These sediments generally were eroded from underlying rock, and then were transported and deposited (USGS Soller and others, 2009). Reach catchment information characterizes data at the local scale.
