Ground water in approximately 400 square miles\nof Quaternary-age alluvial and terrace aquifer is an important\nsource of water for irrigation, industrial, municipal, stock,\nand domestic supplies. The aquifer consists of clay, silt,\nsand, and gravel. Sand-sized sediments dominate the poorly\nsorted, fine to coarse, unconsolidated quartz grains in the\naquifer. The hydraulically connected alluvial and terrace\ndeposits unconformably overlie Permian-age formations. The\naquifer is overlain by a layer of wind-blown sand in parts of\nthe area.\nA uniform recharge rate of 1 inch per year was used as input to\nthe ground-water flow model for the aquifer and is used in this\ndata set.\nThe features representing boundaries along geological contacts\nwere extracted from published digital surficial geology data\nsets based on a scale of 1:250,000. The northwest and southeast\ngeographic limits of the aquifer and were digitized from a\nfolded paper map in a ground-water modeling report, at a scale\nof 1:250,000\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/P9DSV5W5", "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.eb72a029-3a92-49b3-98f2-ddb97f406c31.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_eb72a029-3a92-49b3-98f2-ddb97f406c31", "keyword": ["North Canadian River alluvial and terrace aquifer", "North Canadian alluvial and terrace aquifer", "USGS:eb72a029-3a92-49b3-98f2-ddb97f406c31", "alluvial and terrace aquifer", "alluvial aquifer", "alluvium", "aquifers", "environment", "geoscientificInformation", "ground water", "ground-water recharge", "ground-water vulnerability", "groundwater", "groundwater recharge", "groundwater vulnerability", "inlandWaters", "recharge", "recharge rates", "terrace", "terrace aquifer"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-98.5805, 35.4695, -97.6626, 36.1427", "theme": ["geospatial"], "title": "Digital data sets that describe aquifer characteristics of the alluvial and terrace deposits along the North Canadian River from Canton Lake to Lake Overholser in central Oklahoma"}
