Recent applications for groundwater appropriations \nfrom Dixie Valley, Nevada, a primarily undeveloped basin neighboring the Carson Desert to the east, have prompted \na reevaluation of the quantity of naturally discharging groundwater.The objective of this study was to develop a new, \nindependent estimate of groundwater discharge by evapotranspiration (ET) from Dixie Valley using a combination of \neddy-covariance evapotranspiration measurements and multispectral satellite imagery. Mean annual groundwater ET \n(ETg) was estimated during October 2009-2011 at four eddy covariance sites.  Two sites were located in phreatophytic \nshrubland dominated by greasewood and two were located on a playa.  ETg estimates were scaled to the basin level \nby combining remotely sensed imagery with field reconnaissance and site-scale ETg estimates.  Vegetation index \nand brightness temperature data were used to partition Dixie Valley into five discharging ET units, and scale actual \nand potential ETg to the basin level.ET units were constrained by the groundwater discharge area (GDA) represented \nby this dataset.  The GDA represents the area where discharge from evaporation by open water or bare soil and \ntranspiration from phreatophytic plants exceeds the volume of water contributed by precipitation. The GDA was \ndelineated during field reconnaissance of the study area.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P91G7R8C", "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.c4a331ae-6c19-4815-9f7c-39e4dda5b4ae.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_c4a331ae-6c19-4815-9f7c-39e4dda5b4ae", "keyword": ["Churchill County", "Dixie Valley", "ET", "ET unit", "Evaporation", "Evapotranspiration", "Great Basin", "Groundwater", "Groundwater discharge", "Nevada", "Pershing County", "Phreatophyte", "Transpiration", "USGS:c4a331ae-6c19-4815-9f7c-39e4dda5b4ae", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-118.161441, 39.627578, -117.583910, 40.155693", "theme": ["geospatial"], "title": "Groundwater Discharge Area for Dixie Valley, Churchill County, Nevada"}
