A finite-difference, inverse groundwater flow model of Pahute Mesa, Nevada Test Site, Nye County, Nevada
(University of Nevada, Reno, 1994)A finite-difference inverse groundwater flow model was developed for Pahute Mesa located in Nye County, Nevada. The model results appear to support the existence of a hydraulic barrier at Pahute Mesa. -
