Hydrological and thermal response of lakes to climate: Description and modeling
Steven W. Hostetler
1995, Book chapter, Physics and chemistry of lakes
Lake systems continually respond to climatic conditions that vary over broad scales of space and time. The spatial distribution of lakes on the Earth’s surface is indicative of long-term patterns of atmospheric circulation, and the annual cycle of climate over lake basins is reflected in seasonal change in the size...

Warren W. Wood, Ward E. Sanford
1995, Water Resources Research (31) 3121-3129
Eolian processes associated with saline lakes are shown to be important in determining solute concentration in groundwater in arid and semiarid areas. Steady state mass balance analyses of chloride in the groundwater at Double Lakes, a saline lake basin in the southern High Plains of Texas, United States, suggest that...
Comment on "Horizontal aquifer movement in a theis-theim confined system" by Donald C. Helm
Paul A. Hsieh, Richard L. Cooley
1995, Water Resources Research (31) 3107-3111
In a recent paper, Helm [1994] presents an analysis of horizontal aquifer movement induced by groundwater withdrawal from a confined aquifer in which fluid and grains are incompressible. The analysis considers the aquifer in isolation (ignoring overlying and underlying strata) and assumes that the aquifer deforms purely in the horizontal...
