The complex \nhydrologic system of the Central Valley is simulated using the USGS numerical modeling code MODFLOW-FMP \n(Schmid and others, 2006).  This simulation 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.  The CVHM includes complex surface-water management \nprocesses.  The hydrology of the present-day Central Valley and the CVHM model are driven by surface-water \ndeliveries and associated groundwater pumpage.  The Streamflow Routing Package (SFR1) is linked to \nMODFLOW-FMP to facilitate the simulated conveyance of surface-water deliveries. If surface-water deliveries \ndo not meet the farm delivery requirement, the FMP invokes simulated groundwater pumping to meet the \ndemand.  The surface-water network represents a subset of the entire stream network in the valley.  Even \nso, 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 \nnon-routed deliveries.  Most of these inflows are regulated by dams and most of the deliveries conveyed \nare through an extensive canal network.  The routed deliveries are convyed through the simulated surface-water \nnetwork, while the non-routed delivery conveyance typically occurs through small canals or diversion ditches \nand are not directly simulated. Much of the surface-water diversion and delivery information was compiled by \nthe California Department of Water Resources (DWR) for 21 water-balance subregions (WBSs) covering the \nvalley floor (C. Brush, California Department of Water Resources, written commun., February 21, 2007).  The \nCVHM is the most recent regional-scale model of the Central Valley developed by the U.S. Geological Survey \n(USGS).The CVHM was developed as part of the USGS Groundwater Resources Program (see \"Foreword\", \nChapter A, page iii, for details).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9PJFVNT", "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.a97e6d2c-bbfa-468a-b7ca-2606f27b2c0b.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_a97e6d2c-bbfa-468a-b7ca-2606f27b2c0b", "keyword": ["inlandWaters", "Calaveras County", "Flow Model CVHM", "Yuba County", "Texture Model", "Ventura County", "Humboldt County", "Central Valley", "San Joaquin Valley", "Tuolumne County", "Butte County", "Stanislaus County", "San Joaquin County", "Fresno County", "Contra Costa County", "Central Valley, California", "Napa County", "Tulare County", "Nevada County", "Madera County", "Santa Clara County", "Shasta County", "surface water", "hydrogeology", "Tehama County", "San Luis Obispo County", "model", "California", "geoscientificinformation", "groundwater", "Kern County", "Sacramento County", "Mendocino County", "Yolo County", "Solano County", "CV-RASA", "Mariposa County", "Placer County", "Glenn County", "Sacramento Valley", "USGS:a97e6d2c-bbfa-468a-b7ca-2606f27b2c0b", "Lake County", "hydrology", "Central Valley Aquifer", "Monterey County", "Central Valley Hydrologic Model", "El Dorado County", "Alameda County", "Trinity County", "Kings County", "Santa Barbara County", "Merced County", "Sutter County", "Colusa County", "Amador County", "Sonoma County", "Groundwater Availability of the Central Valley Aquifer", "San Benito County"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.534013, 35.228509, -118.712157, 40.615989", "theme": ["geospatial"], "title": "Surface-Water Network for the Central Valley Hydrologic Model (CVHM)"}
