Abstract: Over the last 20 years, numerous studies of soil-moisture flux and/or ground-water recharge have been conducted on the U.S. Department of Energy's (DOE) Nevada Test Site (NTS) in southern Nevada. These studies have been undertaken to assess the magnitude of contaminant transport potential in the soil zone, as water balance studies in arid zone plant communities, and to provide boundary conditions for numerical models of ground-water flow in the aquifers beneath the testing area. These studies have been conducted on a wide range of geomorphic and topographic environs as well as in areas disturbed by man's activity. In this paper, a review of several of the most relevant studies are presented to demonstrate the wide range of recharge conditions found on the NTS and to discuss the errors associated with the techniques employed to estimate the flux of soil water.
