Simulated potentiometric surface contours of prepumping conditions in layer 1 of the transient ground-water flow model of the Death Valley regional ground-water flow system, Nevada and California

These simulated potentiometric surface contours represent prepumping (or steady-state) conditions for model layer 1 of the Death Valley regional ground-water flow...该模拟测压水面等值线（simulated potentiometric surface contours）表征了死亡谷区域地下水流模型第1层的抽水前（或稳态）条件。
