These methods are used to provide estimates of peak-flow quantiles for 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs). Annual peak-flow data used in the peak-flow frequency analysis for these streamgages were retrieved from the U.S. Geological Survey National Water Information System webpage (U.S. Geological Survey, 2020) and used with USGS flood-frequency analysis software PeakFQ (Veilleux and others, 2014). This data release contains annual peak-flow data (Iowa_ffa_2019_WATSTORE.txt), PeakFQ specifications (Iowa_ffa_2019.psf), and a series of tables describing the methods and results of the peak-flow frequency analysis (Iowa_ffa_2019.xlsx).\nReferences Cited:\nEash, D.A., Barnes, K.K., and Veilleux, A.G., 2013, Methods for estimating annual exceedance-probability discharges for streams in Iowa, based on data through water year 2010: U.S. Geological Survey Scientific Investigations Report 2013-5086, 63 p. with appendix., http://pubs.usgs.gov/sir/2013/5086/.\nU.S. Geological Survey, 2020, USGS water data for the Nation: U.S. Geological Survey National Water Information System database, accessed June 25, 2020, accessed June 25, 2020, at https://doi.org/10.5066/F7P55KJN.\nVeilleux, A.G., Cohn, T.A., Flynn, K.M., Mason, R.R., Jr., and Hummel, P.R., 2014, Estimating magnitude and frequency of floods using the PeakFQ 7.0 program: U.S. Geological Survey Fact Sheet 2013\u20133108, 2 p., https://dx.doi.org/10.3133/fs20133108.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9W7VP64", "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.5f10a1a582ce21d4c4079751.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5f10a1a582ce21d4c4079751", "keyword": ["Cedar River", "Correctionville", "Iowa", "Janesville", "Little Sioux River", "USGS:5f10a1a582ce21d4c4079751", "Waverly", "annual exceedance probability", "hydrology", "peak-flow frequency", "streamflow"], "modified": "2021-02-18T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-96.6557, 40.5651, -90.1340, 43.5012", "theme": ["geospatial"], "title": "Peak-flow frequency analysis for three selected streamgages in the Cedar and Little Sioux River Basins, Iowa, based on data through water year 2019"}
