Literature Review and Annotated Bibliography: Water Requirements of Desert Ungulates
James W. Cain III, Paul R. Krausman, Steven S. Rosenstock, Jack C. Turner
2005, Open-File Report 2005-1141
Executive Summary Ungulates adapted to desert areas are able to survive extreme temperatures and limited water availability. This ability is largely due to behavioral, morphological, and physiological adaptations that allow these animals to avoid or tolerate extreme environmental conditions. The physiological adaptations possessed by ungulates for thermoregulation and maintenance of water...

Hydrogeology of the Mogollon Highlands, central Arizona
John T.C. Parker, William C. Steinkampf, Marilyn E. Flynn
2005, Scientific Investigations Report 2004-5294
The Mogollon Highlands, 4,855 square miles of rugged, mountainous terrain at the southern edge of the Colorado Plateau in central Arizona, is characterized by a bedrock-dominated hydrologic system that results in an incompletely integrated regional ground-water system, flashy streamflow, and various local water-bearing zones that are sensitive to drought. Increased...
Simulated water-level responses, ground-water fluxes, and storage changes for recharge scenarios along Rillito Creek, Tucson, Arizona
John P. Hoffmann, Stanley A. Leake
2005, Scientific Investigations Report 2004-5286
A local ground-water flow model is used to simulate four recharge scenarios along Rillito Creek in northern Tucson to evaluate mitigating effects on ground-water deficits and water-level declines in Tucson's Central Well Field. The local model, which derives boundary conditions from a basin-scale model, spans the 12-mile reach of Rillito...
