Summary

This tabular data set represents the percent of surficial materials 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 "Map database for surficial materials in the conterminous United States" produced by the United States Geological Survey (USGS, 2009). Units are percent. 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 [...]

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 surficial materials for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
