Summary

This tabular data set represents mean infiltration-excess overland flow as a percent of streamflow, 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 from "Infiltration-excess overland flow estimated by TOPMODEL for the conterminous United States" produced by the United States Geological Survey (Wolock, 2003). The data represent the average percentage of infiltration-excess overland flow in total streamflow. Units are percentage of total streamflow. [...]

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 mean infiltration-excess overland flow as a percent of streamflow, 2002 for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
