Reference springs in California for the regional ground-water potential map by Bedinger and Harrill (2004), Death Valley regional ground-water flow system, Nevada and California

This digital geospatial data set is a compilation of reference points representing springs in California that were used for the regional ground-water potential map by Bedinger and Harrill (2004). The regional ground-water potential map was developed to assess potential interbasin flow in the Death Valley regional ground-water flow system (DVRFS), a 100,000-square-kilometer region of southern Nevada and California. To obtain an adequate network of control points, Bedinger and Harrill (2004) used regional potential altitudes derived from surface-water features, ground-water levels, topographic settings and deep wells in addition to the 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).本数字地理空间数据集为加利福尼亚州泉点参考点位的汇编成果，这些点位曾被Bedinger与Harrill（2004）用于绘制区域地下水势（ground-water potential）图。该区域地下水势图的编制目的是评估死亡谷区域地下水流系统（DVRFS）内的跨盆地潜在水流，该系统覆盖内华达州南部与加利福尼亚州境内共计10万平方千米的范围。为构建足量的控制点网络，Bedinger与Harrill（2004）在纳入泉点数据的基础上，还使用了由地表水特征、地下水位、地形环境以及深井数据推导得到的区域势位高程。二人还制定了一套通用指南，用于将区域地下水势与这些更易观测的地表及近地表地下水位，以及DVRFS内地下水盆地的水文特征相关联（详见"大型成果引用"附录1）。
