Regression regions for estimating magnitude and frequency of floods in and near Virginia and West Virginia, 2025

This metadata describes source data and processing steps for creating a geospatial dataset containing the hydrologic regions used in the 2025 Virginia and West Virginia flood-frequency analysis (Messinger and Other, 2025). These twelve regions are the results of an exploratory analysis process described in more detail within the manuscript. Regression regions for the study area are provided in shapefile format in "Regression_Regions.shp"; shapefile components are compressed within a folder named "Regression_Regions.zip"
