Special conditions can include data-collection conditions, basin conditions, flood-generating mechanisms, or other information and can be critical for informing hydrologic analyses such as flood frequency analysis. The dataset contains three tables: (1) table of peak flows identified as extreme floods in Alaska through water year 2022, selected associated special conditions and climate information, and results of an assessment of flood-generating mechanisms, (2) a table of atmospheric river presence or absence data for Alaska for 1980-2019 that were used to assess peak-flow conditions, and (3) a table of input data and results for a drainage area-precipitation cluster analysis for 455 streamgages in Alaska.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1C5KFBH", "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.685d7501d4be02077e8f43a4.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_685d7501d4be02077e8f43a4", "keyword": ["Discharge/flow", "Floods", "Hydrographic datasets", "Hydrology", "InlandWaters", "Rivers/streams", "Terrestrial Hydrosphere", "Time series datasets", "USGS:685d7501d4be02077e8f43a4"], "modified": "2025-06-26T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-168.93, 52.05, -125.86, 71.86", "theme": ["geospatial"], "title": "Extreme Flood, Atmospheric River Presence, and Basin Characteristic Data for a Study of Peak Streamflow Special Conditions in Alaska"}
