The Central Valley encompasses an approximate 50,000 square-kilometer \nregion of California. The complex hydrologic system of the Central Valley is simulated using the USGS numerical modeling \ncode, MODFLOW-FMP (Schmid and others, 2006).  This application is referred to here as the Central Valley Hydrologic \nModel (CVHM) (Faunt, 2009). Utilizing MODFLOW-FMP, the CVHM simulates groundwater and surface-water flow, irrigated \nagriculture, land subsidence, 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. Slightly less \nthat 50 percent of the cells are active. The CVHM grid has a uniform horizontal discretization of 1x1 square mile and is \noriented parallel to the valley axis, 34 degrees west of north (Faunt, 2009). The CVHM is the most recent regional-scale \nmodel of the Central Valley developed by the U.S. Geological Survey (USGS).  The CVHM was developed as part of the \nUSGS Groundwater Resources Program (see \"Foreword\", Chapter A, page iii, for details).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P94LLN83", "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.35bec99d-bdb3-42ae-859a-cff327177bd2.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_35bec99d-bdb3-42ae-859a-cff327177bd2", "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:35bec99d-bdb3-42ae-859a-cff327177bd2", "Ventura County", "Yolo County", "Yuba County", "flow system", "groundwater", "hydrogeology", "hydrology", "inlandWaters", "model", "surface water"], "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": "Location of General Head Boundaries (GHB) in the Central Valley Hydrologic Model (CVHM)"}
