Basin characteristics considered for multiple regression analysis for 1050 selected streamgages in and near Virginia and West Virginia, 2025

This child page contains the drainage basin characteristics that were computed for each drainage basin and considered to be potential explanatory variables in multiple regression analysis in the 2025 VA-WV flood-frequency analysis. The six tables are grouped by source datasets and include: 1) Table_9_L3_Ecoregions.txt: Contains area and percent of Level III ecoregions from the Environmental Protection Agency within each basin 2) Table_10_L4_Ecoregions.txt:Contains area and percent of Level IV ecoregions from the Environmental Protection Agency within each basin 3) Table_11_Land_Cover_2019.txt: Contains area and percent of land cover classes from the 2019 National Land Cover Dataset within each basin 4) Table_12_Miscellaneous.txt: Contains miscellaneous information about selected geographic, geometric, and geologic properties of each basin 5) Table_13_Physiography.txt: Contains area and percent of physiographic provinces from Fenneman and Johnson, 1946 within each basin 6) Table_14_Precipitation.txt: Contains the mean annual precipitation from PRISM and the mean precipitation at selected recurrence intervals from NOAA Atlas 14 for each basin 7) Table_15_BC_Evaluation.txt: A subset of 121 of these basin characteristics were evaluated using correlation and scatterplot matrices and results are summarized 8) Table_17_Drainage_Basin_Areas_within_Regions.txt: Contains the total area and percentage of area of each hydrologic regression region within each streamgage drainage basin The associated child page titled "Drainage basin polygons and outlet points for 1050 selected streamgages in and near Virginia and West Virginia, 2025" contains geospatial layers of drainage outlet points and drainage basin boundaries that were generated in this study. These shapefiles can be merged with the basin characteristics files using the Station_ID field.
