Description:

Abstract:

This digital data set represents the constant-head boundary used to simulate ground-water inflow or outflow at the lateral boundary of the Death Valley regional ground-water flow system (DVRFS) transient model. The area simulated by the DVRFS transient ground-water flow model is an approximately 45,000 square-kilometer region of southern Nevada and California. The hydraulic heads imposed at the constant-head cells were interpolated from a regional potentiometric surface ("Larger Work Citation", Appendix 1). Quantity of ground-water flow at the constant-head boundary was estimated using water-budget and Darcy calculations ("Larger Work Citation", Appendix 2), and was used as observation information during calibration of the DVRFS model (Faunt and others, 2004). The DVRFS transient ground-water flow model is one of the most recent in a number of regional-scale models developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy (DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada (see "Larger Work Citation", Chapter A, page 8).

Purpose:

The constant-head boundary data set was used to develop input to MODFLOW-2000, the USGS 3D finite-difference code used to simulate ground-water flow in the DVRFS. The estimate of flow at the constant-head boundary was used as a component of the water budget and also to develop constant-head observations for calibrating the DVRFS transient ground-water flow model.

Supplemental_Information:

The simulated constant-head boundary data set is one of many layers in a geospatial database supporting the USGS DVRFS project. During this 5-year (1998-2004) project the USGS, in cooperation with DOE and other Federal, State, and local agencies, developed this geospatial database for a regional-scale, 3D hydrogeologic framework model (HFM) and a ground-water flow model. The models are intended to address water-resource issues and the potential movement of radioactive material from the Nevada Test Site and the proposed high-level nuclear waste repository at Yucca Mountain, Nevada.

Data from two previous ground-water flow models of the greater Death Valley region (see "Larger Work Citation", Chapter A, p. 7) were the foundation of the DVRFS geospatial database. Those and other data were reexamined through a series of regional-scale hydrologic investigations to provide updated and spatially consistent interpretations for the DVRFS study. In some cases, new data were collected to augment the existing information. Data compiled from the studies include natural ground-water discharge occurring through evapotranspiration and spring flow; ground-water pumping for the period 1913-98; ground-water recharge simulated as net infiltration; ground-water inflow and outflow at lateral model boundaries; hydraulic conductivity and its relation to depth and other rock properties; and the estimation of water levels representative of prepumped and pumped conditions in the region. Digital elevation models, geologic maps, borehole information, cross sections, and other 3D models were used to develop the HFM which represents the geometry of 27 hydrogeologic units and structural features. The resulting geospatial database supports characterization and conceptualization of the DVRFS, construction of 3D hydrogeologic framework and ground-water flow models, and visualization of analysis and model results.

Process_Step:

Process_Description:

A GIS was used to develop a polygon layer representing the flow-model grid, and constant-head cells were specified along the lateral-flow boundary where inflow and outflow were thought to occur. This included the spatial extent of inflow and outflow areas defined by Harrill and Bedinger (2004) and the model layers that included alluvium, volcanic, or carbonate rock units below the regional potentiometric surface (Bedinger and Harrill, 2004). The constant-head cells (polygons) were attributed with hydraulic-head values interpolated from the regional potentiometric surface (Bedinger and Harrill, 2004). The constant-head cells were also attributed with estimates of lateral flux made for each of the 12 boundary segments using water budget and Darcy calculations (Harrill and Bedinger, 2004). Faunt and others (2004, table F-2) used the segment number and name and the lateral-flux estimates to develop observations for model input and calibration.
