Faunt", "hasEmail": "mailto:ccfaunt@usgs.gov"}, "description": "A three-dimensional groundwater flow model (MODFLOW200-FMP1_1) of the Central Valley in \nCalifornia was developed to aid water managers in understanding how water moves through the \naquifer system, to predict water-supply scenarios, and to address issues related to water \ncompetition.  The USGS Groundwater Resources Program made a detailed assessment of \ngroundwater availability of the Central Valley aquifer system, which includes: \n(1) the present status of groundwater resources; \n(2) how these resources have changed over time; and \n(3) tools to assess system responses to stresses from future human uses and climate \nvariability and change. This effort builds on previous investigations, such as the USGS \nCentral Valley Regional Aquifer System and Analysis (CV-RASA) project and several \nother groundwater studies in the Valley completed by Federal, State and local agencies \nat differing scales. The principal product of this new assessment is a tool referred to as \nthe Central Valley Hydrologic Model (CVHM) that accounts for integrated, variable water \nsupply and demand, and simulates surface-water and groundwater-flow across the entire \nCentral Valley system.  The current model was extended to incorporate a slightly larger \ngeographic area, has a finer spatial and temporal discretization, uses a more-detailed \ndepiction of subsurface geology.  In addition, the model utilizes a modified version of \nMODFLOW2000 (version 1.15.03) to include an updated and refined Farm Process (FMP1) \nto simulate groundwater and surface-water flow, irrigated agriculture, land subsidence, and \nother key processes in the Central Valley on a monthly basis for April 1961 through \nSeptember 2003. This USGS data release contains all of the input and output files for \nthe simulation and calibration of the CVHM described in the associated model \ndocumentation report (https://pubs.er.usgs.gov/publication/pp1766).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F79S1PX3", "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.b2208769-41a1-4cca-9554-56cbffd0605e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_b2208769-41a1-4cca-9554-56cbffd0605e", "keyword": ["California", "Central Valley", "Corcoran Clay", "Groundwater", "Groundwater Model", "InlandWaters", "MODFLOW", "MODFLOW2000", "MODFLOW2000_FMP1_1", "Sacramento Valley", "San Joaquin Basin", "San Joaquin Formation", "San Joaquin Valley", "Tulare Basin", "UCODE-2005", "USGS:b2208769-41a1-4cca-9554-56cbffd0605e", "alluvial aquifer", "environment", "geoscientificInformation", "inlandWaters", "usgsgroundwatermodel"], "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": "MODFLOW2000_FMP1_1 model used to simulate the groundwater flow of the Central Valley Aquifer, California"}
