The Central Valley encompasses an \napproximate 50,000 square-kilometer region of California. The complex hydrologic system of the Central \nValley is simulated using the U.S. Geological Survey(USGS) numerical modeling code MODFLOW-FMP \n(Schmid and others, 2006).  This application is referred to here as the CVHM (Faunt, 2009). Utilizing \nMODFLOW-FMP, the CVHM simulates groundwater and surface-water flow, irrigated agriculture, land \nsubsidence, and other key processes in the Central Valley on a monthly basis from 1961-2003.  The total \nactive modeled area is 20,334 square-miles on a finite difference grid comprising 441 rows and 98 columns. \nSlightly less than 50 percent of the cells are active. The CVHM model grid has a uniform horizontal \ndiscretization of 1x1 square mile and is oriented parallel to the valley axis, 34 degrees west of north \n(Faunt, 2009). Groundwater pumpage is a major part of the groundwater budget of the Central Valley, \nand is grouped into two categories for this study: agricultural and urban (which includes municipal and \nindustrial sources))(Diamond and Williamson, 1983). Urban wells were simulated as multi-node wells \n(Halford and Hanson, 2002) (Faunt, 2009; fig. C3). In each WBS, a single well was placed in each model \ncell where the predominant land use for a given time frame was urban (Brush, 2007). Because the extent \nof urban areas changes through time, wells were added and deleted accordingly in the model during the \nsimulation period. In general, agricultural wells were replaced by urban wells in the model as the land use \nchanged from agricultural to urban. The single well per model cell represents the composite of all wells in \neach square-mile cell and is referred to here as a virtual well. The CVHM is the most recent regional-scale \nmodel of the Central Valley developed by the USGS. The CVHM was developed as part of the USGS \nGroundwater Resources Program (see \"Foreword\", Chapter A, page iii, for details).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9AE4V4L", "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.5e0a5182-1a30-40a1-aa6d-a87e165ebced.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5e0a5182-1a30-40a1-aa6d-a87e165ebced", "keyword": ["Alameda County", "Amador County", "Butte County", "CV-RASA", "Calaveras County", "California", "Central Valley", "Central Valley Aquifer", "Central Valley Hydrologic Model", "Central Valley, California", "Colusa County", "Contra Costa County", "El Dorado County", "Flow Model CVHM", "Fresno County", "Glenn County", "Groundwater Availability of the Central Valley Aquifer", "Humboldt County", "Kern County", "Kings County", "Lake County", "Madera County", "Mariposa County", "Mendocino County", "Merced County", "Monterey County", "Napa County", "Nevada County", "Placer County", "Sacramento County", "Sacramento Valley", "San Benito County", "San Joaquin County", "San Joaquin Valley", "San Luis Obispo County", "Santa Barbara County", "Santa Clara County", "Shasta County", "Solano County", "Sonoma County", "Stanislaus County", "Sutter County", "Tehama County", "Texture Model", "Trinity County", "Tulare County", "Tuolumne County", "USGS:5e0a5182-1a30-40a1-aa6d-a87e165ebced", "Ventura County", "Yolo County", "Yuba County", "environment", "geoscientificInformation", "groundwater", "hydrogeology", "hydrology", "inlandWaters", "model", "pumpage", "virtual well"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-123.831528, 34.519871, -117.916328, 40.748631", "theme": ["geospatial"], "title": "Monthly urban (municipal and industrial use) pumpage for the Central Valley Hydrologic Model (CVHM) by Water Balance Subregion (WBS)"}
