Study area boundary for the Death Valley regional ground-water flow system, Nevada and California

This digital data set represents the Death Valley regional ground-water flow system (DVRFS) study area which encompasses approximately 100,000-square kilometers in Nevada and California and is bounded by latitudes 35-degrees north and 38-degrees 15-minutes north and by longitudes 115-degrees west and 118-degrees west. The study area boundary encompasses the DVRFS model domain which is the area simulated by a transient ground-water flow model. The DVRFS transient ground-water flow model is the most recent in a number of regional-scale models developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy (DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada (see "Larger Work Citation", Chapter A, page 8, for details).本数字数据集表征死亡谷区域地下水流系统（DVRFS，Death Valley Regional Ground-Water Flow System）的研究区，该研究区覆盖内华达州与加利福尼亚州境内约10万平方千米范围，其地理边界为北纬35°至北纬38°15′，西经115°至西经118°。该研究区的边界涵盖DVRFS模型域，即由暂态地下水流模型（transient ground-water flow model）模拟的区域。该DVRFS暂态地下水流模型是美国地质调查局（U.S. Geological Survey，缩写USGS）为美国能源部（U.S. Department of Energy，缩写DOE）支持内华达试验场（Nevada Test Site，缩写NTS）及内华达州尤卡山相关调查工作所开发的一系列区域尺度模型中的最新版本，详细信息参见"Larger Work Citation", A章节第8页。
