In total, 938 Groundwater Units are represented.  The Groundwater Unit dataset relates \nexisting groundwater basins with their newly delineated highland areas which can be used in \nsubsequent hydrologic studies.  The method used to delineate highland areas is similar to \nmethods used to delineate a contributing area, the difference being that highland areas are \nconstrained to the immediately surrounding upslope (upsteam) area.\n\t\t\nHighland areas were delineated based upon the surficial contributing area (watershed) immediately \nadjacent to each groundwater basin.  The method of delineation is comparable to the method used \nfor stream segments.  However, highland areas are not intended to represent the entire surficial \ncontributing area for a groundwater basin.  Upslope (upstream) groundwater basins, which may \nbe contiguous with a downstream basin, are not included in the delineation for the downstream \nbasin because the upstream basins will have their own highland areas delineated.  In addition, \nmany groundwater basins in the Central Valley are divided along a river:  one groundwater basin \nalong the right bank, and another along the left bank.  Therefore, each groundwater basin will \nhave its own highland area delineated for each side of the river.  Groundwater units can be \ncombined if desired.\n\t\t\nSome groundwater basins do not have an associated highland because the basin was completely \nbordered by other groundwater basins, or a combination of groundwater basins and the ocean.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P92CZJAK", "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.be0149a2-0a0a-4387-b9d7-a4611b7827cd.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_be0149a2-0a0a-4387-b9d7-a4611b7827cd", "keyword": ["California", "GAMA", "Groundwater", "Groundwater Ambient Monitoring Assessment Program", "Groundwater basin", "Highland areas", "USGS:be0149a2-0a0a-4387-b9d7-a4611b7827cd", "United States", "Western United States", "environment", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-124.507642, 32.425413, -113.488240, 42.067151", "theme": ["geospatial"], "title": "DS796  California Groundwater Units"}
