Ground water in 830 square miles of the\nQuaternary-age alluvial and terrace aquifer is an important\nsource of water for irrigation, industrial, municipal, stock,\nand domestic supplies. The aquifer consists of poorly sorted,\nfine to coarse, unconsolidated quartz sand with minor amounts of\nclay, silt, and basal gravel. The hydraulically connected\nalluvial and terrace deposits unconformably overlie the\nTertiary-age Ogallala Formation and Permian-age formations.\nA recharge rate of 1 inch per year was estimated in the\nground-water modeling report for the alluvial and terrace\ndeposits and used in this data set. The recharge rate was\nestimated using a base-flow method and a monthly-water-balance\nmethod.\nThe features in the data set representing boundaries along\ngeological contacts were extracted from a published digital\nsurficial geology data set based on a scale of 1:250,000. The\ngeographic limits of the aquifer were digitized from a folded\npaper map, at a scale of 1:250,000 in the ground-water\nmodeling report.\nGround-water flow models are numerical representations that\nsimplify and aggregate natural systems. Models are not unique;\ndifferent combinations of aquifer characteristics may produce\nsimilar results. Therefore, values of recharge used in the\nmodel and presented in this data set are not precise, but are\nwithin a reasonable range when compared to independently\ncollected data.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9HM70KG", "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.95e20cc4-52ef-46f5-8065-fca5055def34.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_95e20cc4-52ef-46f5-8065-fca5055def34", "keyword": ["Beaver River alluvial and terrace aquifer", "Beaver alluvial and terrace aquifer", "North Canadian River alluvial and terrace aquifer", "North Canadian alluvial and terrace aquifer", "USGS:95e20cc4-52ef-46f5-8065-fca5055def34", "alluvial and terrace aquifer", "alluvial aquifer", "alluvium", "aquifers", "environment", "geoscientificInformation", "ground water", "ground-water recharge", "ground-water vulnerability", "groundwater", "groundwater vulnerability", "inlandWaters", "recharge", "recharge rate", "terrace", "terrace aquifer", "terrace deposit"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-99.9650, 36.0439, -98.5487, 36.9727", "theme": ["geospatial"], "title": "Digital data sets that describe aquifer characteristics of the alluvial and terrace deposits along the Beaver-North Canadian River from the panhandle to Canton Lake in northwestern Oklahoma"}
