Book Description
Estimates of ground-water recharge rates developed from hydrologic modeling studies are presented for 3-Springs and East Stewart basins, two small basins (analog sites) located in central Nevada. The analog-site studies were conducted to aid in the estimation of recharge to the paleohydrologic regime associated with ground water in the vicinity of Yucca Mountain under wetter climatic conditions. The two analog sites are located to the north and at higher elevations than Yucca Mountain, and the prevailing (current) climatic conditions at these sites is thought to be representative of the possible range of paleoclimatic conditions in the general area of Yucca Mountain during the Quaternary. Two independent modeling approaches were conducted at each of the analog sites using observed hydrologic data on precipitation, temperature, solar radiation, stream discharge, and chloride-ion water chemistry for a 6-year study period (October 1986 through September 1992). Both models quantify the hydrologic water-balance equation and yield estimates of ground-water recharge, given appropriate input data. Results of the modeling approaches support the conclusion that reasonable estimates of average-annual recharge to ground water range from about 1 to 3 centimeters per year for 3-Springs basin (the drier site), and from about 30 to 32 centimeters per year for East Stewart basin (the wetter site). The most reliable results are those derived from a reduced form of the chloride-ion model because they reflect integrated, basinwide processes in terms of only three measured variables: precipitation amount, precipitation chemistry, and streamflow chemistry.

Book Description
The purposes of this investigation were to: define the hydraulic character and subsurface distribution of the major aquifers and aquitards; identify and describe the principal areas of recharge to and discharge from the major aquifers; and determine the rate and the direction of ground-water movement within the major aquifers and aquitards. Of these objectives, the third was of prime importance for an evaluation of the rate of movement of various radionuclides from the vicinity of an underground nuclear detonation. The accuracy of the velocity estimates, however, rested heavily upon the other two study objectives. The Nevada Test Site occupies a small part of two ground-water basins - the Ash Meadows and the Oasis Valley-Fortymile Canyon basins. Consequently, the objectives are discussed for a region several times the size of the test site.
