MODFLOW-2005 model used to estimate paleo-recharge volumes and project future water-level changes in Ash Meadows groundwater basin, southwest Nevada, based on Devils Hole paleo-water-table record

This data release documents a modified version of the Death Valley version 3 steady-state (DV3-SS) model described in U.S. Geological Survey Professional Paper 1863 (https://doi.org/10.3133/pp1863). The DV3-SS model was modified by conversion into a superposition model with initial heads of 0 ft (0 m). Simulated water-level changes are relative to modern, predevelopment (pre-1950) conditions, where modern levels have a reference datum of 0 ft (0 m). The modified DV3-SS model is a three-dimensional, groundwater model (MODFLOW-2005) that was used to estimate paleo-recharge in the Ash Meadows groundwater basin, southwest Nevada, using the Devils Hole (cave 2) water-table record that spans the last 350,000 years. Two steady-state (paleo-recharge) [...]
