<https://data.amerigeoss.org/dataset/4d95cc24-a503-4ace-8dea-3a6dc9753833> a dcat:Dataset ;
    dct:description """This tabular data set represents the mean percent impervious surface from the Imperviousness 
Layer of the National Land Cover Dataset 2001,  (LaMotte and Wieczorek, 2010), compiled for 
every MRB_E2RF1 catchment of selected Major River Basins (MRBs, Crawford and others, 2006). 
The source data set represents imperviousness for the conterminous United States for 2001. The 
Imperviousness Layer of the National Land Cover Data Set for 2001 was produced through a 
cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. 
The MRLC Consortium is a partnership of Federal agencies (http://www.mrlc.gov), consisting of 
the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), 
the U.S. Environmental Protection Agency (USEPA), the U.S. Department of Agriculture (USDA), 
the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service 
(USFWS), the Bureau of Land Management (BLM), and the USDA Natural Resources Conservation 
Service (NRCS).
		
The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection 
Agency's (USEPA) ERF1_2 and include enhancements to support national and regional-scale 
surface-water quality modeling (Nolan and others, 2002;Brakebill and others, 2011).
		
Data were compiled for every MRB_E2RF1 catchment for the conterminous United States covering 
New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the Great Lakes, 
Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the Lower Mississippi, 
Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and the Great basin (MRB6), 
the Pacific Northwest (MRB7) river basins, and California (MRB8).""" ;
