The Central Valley \nencompasses an approximate 50,000 square-kilometer region of California. The complex hydrologic system \nof the Central Valley is simulated using the USGS's numerical modeling code MODFLOW-FMP (Schmid \nand others, 2006).  This simulation is referred to here as the CVHM (Faunt, 2009). Utilizing MODFLOW-FMP, \nthe CVHM simulates groundwater and surface-water flow, irrigated agriculture, land subsidence, and other key \nprocesses in the Central Valley on a monthly basis from 1961-2003.  The total active modeled area is 20,334 \nsquare-miles.   The CVHM includes complex surface-water management processes.  The hydrology of the \npresent-day Central Valley and the CVHM model are driven by surface-water deliveries and associated \ngroundwater pumpage.  The Streamflow Routing Package (SFR1) is linked to MODFLOW-FMP to facilitate \nthe simulated conveyance of surface-water deliveries. If surface-water deliveries do not meet the farm-delivery \nrequirement, the FMP invokes simulated groundwater pumping to meet the demand.  The surface-water \nnetwork represents a subset of the entire stream network in the valley.  Quantitative observations of streamflow \ngains and losses were available for 57 reaches of 20 major stream systems in the Central Valley for water years \n1961-77 (Mullen and Nady, 1985). These observations were included in parameter estimation process and in the \nmodel-fit statistics.  The CVHM is the most recent regional-scale model of the Central Valley developed by the U.S. \nGeological Survey (USGS).  The CVHM was developed as part of the USGS Groundwater Resources Program \n(see \"Foreword\", Chapter A, page iii, for details).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9FIKA9I", "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.0d952ffa-e45b-4463-8769-678f7c0b3a07.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_0d952ffa-e45b-4463-8769-678f7c0b3a07", "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:0d952ffa-e45b-4463-8769-678f7c0b3a07", "Ventura County", "Yolo County", "Yuba County", "geoscientificinformation", "groundwater", "hydrogeology", "hydrology", "inlandWaters", "model", "streamflow", "surface water"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.368562, 35.231481, -118.965852, 40.606449", "theme": ["geospatial"], "title": "Streamflow-gain- and streamflow-loss data for streamgages in the Central Valley Hydrologic Model"}
