Regional potentiometric-surface contours by Bedinger and Harrill (2004), for the Death Valley regional ground-water flow system study, Nevada and California

The contours in this digital data set represent the regional potentiometric surface developed by Bedinger and Harrill (2004) to assess potential interbasin flow in the Death Valley regional ground-water flow system (DVRFS). To obtain an adequate network of control points for that 100,000 square-kilometer region of southern Nevada and California, Bedinger and Harrill (2004) used regional potential altitudes derived from surface-water features, ground-water levels, topographic settings, deep wells, and spring data. A set of general guidelines was developed to relate regional ground-water potential to these more readily observed surface and near-surface ground-water levels and to hydrologic characteristics of ground-water basins in the DVRFS (see "Larger Work Citation", Appendix 1). Bedinger and Harrill (2004) hand-contoured the regional potential data to produce the DVRFS potentiometric-surface map.

本数字数据集的等值线代表了贝丁杰（Bedinger）与哈里尔（Harrill）于2004年为评估死亡谷区域地下水流系统（Death Valley Regional Ground-Water Flow System, DVRFS）中的跨流域潜在水流而开发构建的区域地下水测压面。为在内华达州南部与加利福尼亚州这片10万平方千米的研究区域搭建完备的控制网点网络，贝丁杰与哈里尔（2004）采用了由地表水特征、地下水位、地形背景、深井及泉水数据推求得到的区域势高程。研究团队制定了一套通用指南，用于将区域地下水势与上述更易观测的地表及近地表地下水位，以及DVRFS范围内地下水盆地的水文特征建立关联（详见"Larger Work Citation"附录1）。贝丁杰与哈里尔（2004）通过手工勾绘区域势数据，最终生成了DVRFS地下水测压面等值线图。
