Location of virtual wells used for urban (municipal and industrial use) pumpage in the Central Valley Hydrologic Model (CVHM)
This digital dataset contains the virtual wells used for urban (municipal and industrial use) pumpage for the Central Valley
Hydrologic Model (CVHM). 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). 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. 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).
