Water scarcity is becoming a pervasive and persistent problem in Texas particularly in the drier
regions containing cities like San Antonio, Austin, and Corpus Christi while growth causes
emerging problems in Dallas, Fort Worth and Houston. A...

This report evaluates the performance of a numerical model of the ground-water system in northern Utah Valley, Utah, that originally simulated ground-water conditions during 1947–1980 and was updated to include conditions estimated for 1981–2002....

C. E. Jacob received patents in 1965 for a single location well doublet that would produce fresh water overlying salt-water without upconing of the heavier salt-water and pollution of the fresh water zone. No known evaluation of the concept or...

There is reasonable expectation that climate warming will accelerate the hydrologic cycle, resulting in greater evapotranspiration (ET) and reduced groundwater recharge (R) (or stream flow). Though qualitatively intuitive, quantifying these...

Untreated or improperly treated wastewater has often been cited as the primary
contamination source of groundwater. Decentralized wastewater treatment systems have
applicability around the world since it obviates the need for extensive...

Investigations of water resources systems involving groundwater simulation are generally data-scarce projects. Insufficient geohydrologic data severely inhibits simulation of historic water table behavior. A finite difference model is expanded to...
