Boundary of the area contributing flow to the Death Valley regional ground-water flow system, Nevada and California

This digital data set defines the boundary of the area contributing ground-water flow to the Death Valley regional ground-water flow-system (DVRFS) model domain. The boundary encompasses an approximate 112,000 square-kilometer region and was based on a map of regional potential developed by Bedinger and Harrill (2004). Where possible, the amount of lateral flow across the segments of the DVRFS model boundary from (or to) the contributing area was estimated from ground-water budgets of hydrologic units in the adjacent subregion (see "Larger Work Citation", Appendix 2). The lateral ground-water flow estimates were used to support development of the transient ground-water model of the DVRFS completed in 2004 by the USGS (see "Larger Work Citation", Chapter F).

本数字数据集划定了为死亡谷区域地下水流系统（Death Valley Regional Ground-Water Flow-System, DVRFS）模型域提供地下径流的汇水区边界。该边界覆盖约11.2万平方千米的范围，其划定依据Bedinger与Harrill于2004年编制的区域地下水流势图。在条件允许的前提下，跨DVRFS模型边界段、由该汇水区流入（或流出）的侧向径流量，通过邻近亚区域内水文单元的地下水均衡进行估算（详见附录2「主要著作引用」）。上述侧向地下径流量估算结果，用于支撑美国地质调查局（USGS）于2004年完成的DVRFS非稳定态地下水流模型的研发，相关内容参见章节F「主要著作引用」。
