(editor) 2009 Professional Paper 1766 Reston, Virginia U.S. Geological Survey 3 chapters, 1 appendix http://pubs.usgs.gov/pp/1766/PP_1766.pdf This digital dataset contains the monthly urban (municipal and industrial use) pumpage for the Central Valley Hydrologic Model (CVHM) by Water Balance Subregion (WBS). The Central Valley encompasses an approximate 50,000 square-kilometer region of California. The complex hydrologic system of the Central Valley is simulated using the U.S. Geological Survey(USGS) numerical modeling code MODFLOW-FMP (Schmid and others, 2006). This application is referred to here as the CVHM (Faunt, 2009). Utilizing MODFLOW-FMP, the CVHM simulates groundwater and surface-water flow, irrigated agriculture, land subsidence, and other key processes in the Central Valley on a monthly basis from 1961-2003. The total active modeled area is 20,334 square-miles on a finite difference grid comprising 441 rows and 98 columns. Slightly less than 50 percent of the cells are active. The CVHM model grid has a uniform horizontal discretization of 1x1 square mile and is oriented parallel to the valley axis, 34 degrees west of north (Faunt, 2009). Groundwater pumpage is a major part of the groundwater budget of the Central Valley, and is grouped into two categories for this study: agricultural and urban (which includes municipal and industrial sources))(Diamond and Williamson, 1983). Urban wells were simulated as multi-node wells (Halford and Hanson, 2002) (Faunt, 2009; fig. C3). In each WBS, a single well was placed in each model cell where the predominant land use for a given time frame was urban (Brush, 2007). Because the extent of urban areas changes through time, wells were added and deleted accordingly in the model during the simulation period. In general, agricultural wells were replaced by urban wells in the model as the land use changed from agricultural to urban. The single well per model cell represents the composite of all wells in each square-mile cell and is referred to here as a virtual well. The CVHM is the most recent regional-scale model of the Central Valley developed by the USGS. The CVHM was developed as part of the USGS Groundwater Resources Program (see "Foreword", Chapter A, page iii, for details). The monthly urban pumpage dataset was used as input to MODFLOW-FMP, the USGS 3-dimensional finite-difference code used to simulate flow in the CVHM. The pumpage was split evenly into all the virtual wells in a WBS for the corresponding land-use period. A single well per model cell represents the composite of all wells in each square-mile cell and is referred to here as a virtual well. This is a supporting dataset that provides the CVHM with the monthly pumpage by WBS. The CVHM is a tool that accounts for integrated, variable water supply and demand, and simulates surface-water and groundwater-flow across the entire Central Valley system. The monthly urban pumpage dataset is one of many layers in a geospatial database supporting the USGS Central Valley Groundwater Availability Project. Regional groundwater availability studies quantify current groundwater resources, evaluate how those resources have changed through time, and provide tools that decision makers can use to predict system responses to future development and climate variability and change. To provide information to stakeholders addressing these issues, the USGS made a detailed assessment of groundwater availability of the Central Valley aquifer system, which includes: (1) the present status of groundwater resources; (2) characterization of how these resources have changed over time; and (3) tools to assess system responses to stresses from future human uses and climate variability and change. This effort builds on previous investigations, such as the USGS Central Valley Regional Aquifer System and Analysis (CV-RASA) project and several other groundwater studies in the Valley completed by Federal, State and local agencies at various scales. Data from these previous studies were the foundation of the Central Valley geospatial database. These and other data were re-examined through a series of regional-scale hydrologic investigations to provide updated and spatially consistent interpretations for the Central Valley Groundwater Availability study. In some cases, new data were collected to augment existing information. Data compiled from the studies include geology (in particular, borehole lithology and the extent and thickness of the Corcoran Clay Member of the Tulare Formation), topography, remote sensing, climate (precipitation and temperature), geophysics, vegetation and land use, vegetation properties, hydrology (stream network and flows), groundwater levels, subsidence, chemistry, and soils. Digital elevation models, geologic maps, borehole information, cross sections, and other 3-dimensional models were used to develop the texture model which represents the properties and geometry of the Central Valley alluvial deposits. The resulting geospatial database supports characterization and conceptualization of the Central Valley hydrologic system between 1961 and 2003, construction of 3-dimensional hydrogeologic framework and hydrologic flow models, and visualization of analysis and model results. 2009 publication date Complete None planned -123.831528 -117.916328 40.748631 34.519871 ISO 19115 Topic Category inlandWaters geoscientificinformation American Geological Institute Glossary of Geology (http://glossary.agiweb.org/dbtw-wpd/glossary/search.aspx) hydrology hydrogeology model groundwater pumpage none Groundwater Availability of the Central Valley Aquifer Central Valley Aquifer Central Valley Hydrologic Model Flow Model CVHM Texture Model CV-RASA virtual well U.S. Board of Geographic Names (BGN) and Geographic Names Information System (GNIS) Central Valley, California San Joaquin Valley Sacramento Valley Ventura County Santa Barbara County San Luis Obispo County Kern County Kings County Tulare County Monterey County San Benito County Santa Clara County Fresno County Merced County Madera County Mariposa County Alameda County Stanislaus County Contra Costa County San Joaquin County Tuolumne County Calaveras County Solano County Amador County Sacramento County Napa County Sonoma County Yolo County El Dorado County Placer County Sutter County Colusa County Nevada County Lake County Yuba County Glenn County Mendocino County Butte County Humboldt County Tehama County Shasta County Trinity County Central Valley California Data have been checked to ensure the accuracy of the data.
