![]() These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital dataset defines the SUB package arrays for the model grid, critical head, thickness of fine-grained deposits, and skeletal-elastic-storage used in the transient hydrologic model of the Central Valley flow system. 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 USGS numerical modeling code MODFLOW-FMP...

This digital dataset contains the monthly inflows to the surface-water network 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 USGS numerical modeling code MODFLOW-FMP (Schmid and others, 2006). This simulation is referred to here as the CVHM (Faunt, 2009). Utilizing...

D'Agnese and others (1998) developed a potentiometric surface to conceptualize the regional ground-water flow system and to construct numerical flow models of the Death Valley region, Nevada and California. The estimated potentiometric surface was derived using a gridding algorithm and interactive editing to produce contours representative of the natural water-table conditions. Input data included the altitudes of lakes, springs,...

This digital data set defines the model grid and infiltration values simulated in the transient ground-water flow model of the Death Valley regional ground-water flow system (DVRFS), an approximately 45,000 square-kilometer region of southern Nevada and California. The DVRFS model grid is north-south-oriented, consists of 194 rows and 160 columns, and has a constant grid-cell spacing of 1,500 meters. Model cells are attributed with...

This digital dataset represents the area where lateral flow into and out of the Central Valley groundwater-flow system occurs. The General Head Boundary (GHB) is set to 0 and is only in the Delta and is specified in layer 1 where the groundwater system intersects the surface water system. The Central Valley encompasses an approximate 50,000 square-kilometer region of California. The complex hydrologic system of the Central Valley...

This digital data set defines the subregions of the transient ground-water flow model of the Death Valley regional ground-water flow system (DVRFS). Subregions are used to more readily describe and evaluate the source, occurrence, and movement of ground water within and between the smaller areas of the DVRFS, which is an approximately 45,000 square-kilometer region of southern Nevada and California. The subregions, first described...

Zones in this data set represent spatially contiguous areas that influence ground-water flow in the Death Valley regional ground-water flow system (DVRFS), an approximately 45,000 square-kilometer region of southern Nevada and California. The zones typically represent areas of differing material properties; however, they may also represent spatially similar areas, such as areas of similar infiltration rates. Material properties,...
