Boundary of the ground-water flow model by IT Corporation (1996), for the Death Valley regional ground-water flow system study, Nevada and California

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 data set defines the boundary of the steady-state ground-water flow model built by IT Corporation (1996). The regional, 20-layer ground-water flow model was developed for the Underground Test Area (UGTA) Phase I project to simulate the Nevada Test Site and surrounding areas. The model was used for estimating the amount of water moving through the ground-water system, predicting the movement of contaminants, evaluating uncertainty in these [...]
