Summary

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 [...]

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.
