Regression equations which can be used to estimate flood magnitude and associated frequency at ungaged streams were developed.The methods and results of the study are published in a separate report (https://doi.org/10.3133/sir20235014). \nThis data release includes two geographic information system (GIS) shapefiles, one of polygons representing the extents of the drainage basins of 238 selected streamgages operated by the USGS in the State of Hawai\u02bbi, and the other of polygons representing the extents of flood-regression regions in the State of Hawai\u02bbi. The 238 selected streamgages were used to develop a regional flood skew with Bayesian weighted least squares/Bayesian generalized least squares (B-WLS/B-GLS) regression and were used in generalized least-squares (GLS) regression to generate equations that predict stream discharges corresponding to selected AEPs at ungaged locations on streams in the State of Hawai\u02bbi (Mitchell and others, 2023). Also included is a comma-separated values (.csv) text file containing the physical, land-cover, and climatic characteristics of the basin polygons corresponding to each of the 238 selected streamgages.\nThe data supporting the basin delineations and basin characteristics were previously published as separate data releases: https://doi.org/10.5066/P9N61WJ7, and https://doi.org/10.5066/P9TOQANM.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9GGPPV5", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.62b35e60d34ea7748d9b0907.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_62b35e60d34ea7748d9b0907", "keyword": ["Hawaii", "Hawaii Island", "Kauai", "Maui", "Molokai", "Oahu", "USGS:62b35e60d34ea7748d9b0907", "basin characteristics", "flood estimates", "flood frequency", "hydrology", "linear regression", "peak flows", "weighted regression"], "modified": "2023-05-03T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-160.3500, 18.8000, -154.6500, 22.6000", "theme": ["geospatial"], "title": "Flood-regression regions, basin polygons, and basin characteristics for 238 selected streamgages in Hawai\u02bbi, based on data through water year 2020"}
