Material-property zones used in the transient ground-water flow model of the Death Valley regional ground-water flow system, 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. 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, such as horizontal hydraulic [...]
