Ground water in 830 square miles of the Quaternary-age\nalluvial and terrace aquifer is an important source of water for\nirrigation, industrial, municipal, stock, and domestic supplies.\nThe aquifer consists of poorly sorted, fine to coarse,\nunconsolidated quartz sand with minor amounts of clay, silt, and\nbasal gravel. The hydraulically connected alluvial and terrace\ndeposits unconformably overlie the Tertiary-age Ogallala\nFormation and Permian-age formations.\nSix zones of ranges of hydraulic conductivity values for the\nalluvial and terrace deposits reported in a ground-water\nmodeling report are used in this data set. The hydraulic\nconductivity values range from 0 to 160 feet per day, and\naverage 59 feet per day.\nThe features in the data set representing aquifer boundaries\nalong geological contacts were extracted from a published\ndigital surficial geology data set based on a scale of\n1:250,000. The geographic limits of the aquifer and zones\nrepresenting ranges of hydraulic conductivity values were\ndigitized from folded paper maps, at a scale of 1:250,000\nfrom a ground-water modeling 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 hydraulic conductivity\nused in the model and presented in this data set are not\nprecise, but are within a reasonable range when compared to\nindependently collected data.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P95U0UM2", "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.f0404c74-18b2-4856-beb9-dce3d7ffe870.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_f0404c74-18b2-4856-beb9-dce3d7ffe870", "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:f0404c74-18b2-4856-beb9-dce3d7ffe870", "alluvial and terrace aquifer", "alluvial aquifer", "alluvium", "aquifers", "environment", "geoscientificInformation", "ground water", "ground-water vulnerability", "groundwater", "groundwater vulnerability", "hydraulic conductivity", "inlandWaters", "terrace", "terrace aquifer", "terrace deposits"], "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"}
