The Central Valley encompasses an approximate 50,000 square-kilometer region of California. \nThe complex hydrologic system of the Central Valley is simulated using the U.S. Geological Survey (USGS) numerical \nmodeling code MODFLOW-FMP (Schmid and others, 2006  ).  This simulation is referred to here as the CVHM \n(Faunt, 2009). Utilizing MODFLOW-FMP, the CVHM simulates groundwater and surface-water flow, irrigated agriculture, \nland subsidence, and other key processes in the Central Valley on a monthly basis from 1961-2003.  The total active \nmodeled area is 20,334 square-miles.  The CVHM includes complex surface-water management processes.  The hydrology \nof the present-day Central Valley and the CVHM model are driven by surface-water deliveries and associated groundwater \npumpage.  The Streamflow Routing Package (SFR1) is linked to MODFLOW-FMP to facilitate the simulated conveyance \nof surface-water deliveries. If surface-water deliveries do not meet the farm-delivery requirement, the FMP invokes simulated \ngroundwater pumping to meet the demand.  The surface-water network represents a subset of the entire stream network in \nthe valley.  Even so, it covers about 3,000 kilometers of surface-water and is simulated using 208 stream segments that \nrepresent 2244 stream reaches, with 43 inflows and 66 diversion locations providing 64 routed and 41 non-routed deliveries.  \nMost of these inflows are regulated by dams and most of the deliveries are conveyed through an extensive canal network.  \nThe routed deliveries are conveyed through the simulated surface-water network, while the non-routed delivery conveyance \ntypically occurs through small canals or diversion ditches and are not directly simulated. Much of the surface-water diversion \nand delivery information was compiled by the California Department of Water Resources (DWR) for 21 water-balance subregions \n(WBSs) covering the valley floor (C. Brush, California Department of Water Resources, written commun., February 21, 2007).  \nThe CVHM is the most recent regional-scale model of the Central Valley developed by the USGS.  The CVHM was developed \nas part of the USGS Groundwater Resources Program (see \"Foreword\", Chapter A, page iii, for details).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P94B0A2I", "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.f457f5b3-a855-4bd9-864c-5ff71e4473e5.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_f457f5b3-a855-4bd9-864c-5ff71e4473e5", "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:f457f5b3-a855-4bd9-864c-5ff71e4473e5", "Ventura County", "Yolo County", "Yuba County", "geoscientificinformation", "groundwater", "hydrogeology", "hydrology", "inlandWaters", "model", "reach streams", "segment", "surface water"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.545209, 35.215898, -118.707417, 40.629216", "theme": ["geospatial"], "title": "Grid cells used for Surface-Water Network for the Central Valley Hydrologic Model"}
