Michael E. Wieczorek Andrew E. LaMotte 2010 tabular digital data Digital Data Series DS-491-25 Reston, Virginia U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?mrb_e2rf1_sgeol This tabular data set represents the area of surficial geology types in square meters compiled for every MRB_E2RF1 catchment of selected Major River Basins (MRBs, Crawford and others, 2006). The source data set is the "Digital data set describing surficial geology in the conterminous US" (Clawges and Price, 1999). 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, 2008). 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). This tabular data set was created and used by the U.S. Geological Survey (USGS) specifically to estimate surficial geology areas per watershed segment in the application of the national SPAtially Referenced Regression On Watershed attributes (SPARROW) model . The SPARROW model relates in-stream water-quality measurements to spatially referenced characteristics of watersheds, including contaminant sources and factors influencing terrestrial and stream transport. The model empirically estimates the origin and fate of contaminants in streams, and quantifies uncertainties in these estimates based on model coefficient error and unexplained variability in the observed data. For more information on the USGS SPARROW model please refer to: http://water.usgs.gov/nawqa/sparrow/intro/intro.html. 2002 publication date Complete None planned -127.910792 -65.327751 51.657387 23.243486 None Surficial Geology Inlandwaters MRB_E2RF1 MRB_E2RF1WS Catchment NAWQA SPARROW None Conterminous United States MRB Major River Basins MRB1 NEMA New England and Mid-Atlantic MRB2 SAGT South Atlantic-Gulf and Tennessee MRB3 GLMR Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy MRB4 MORI Missouri MRB5 LMTG Lower Mississippi, Arkansas-White-Red, and Texas-Gulf MRB6 COGB Rio Grande, Colorado, and Great Basin MRB7 PANW Pacific Northwest MRB8 CALI California None None Michael E.

The COMBINE command combines the geology and catchment GRIDs into one coverage. The resulting GRID automatically tables the area of each geology type per catchment. 4) Exported results into a dbf file format. 2008 sgeol_rf1 dbf tabular table ESRI OID Internal feature number ESRI Sequential unique whole numbers that are automatically generated RF1ID Unique ID to relate to the item MRB_ID in the MRB_E2RF1WS catchment and MRB_E2RF1 reach coverages.
