The hydroscience community recently lost one of its true leaders. In rainy weather on December 14, 1993, Shirley Dreiss lost her life in a collision with a cement truck while driving from Santa Cruz, Calif., to San Francisco Airport.
Shirley, 44, was professor and chair of the Department of Earth Sciences at the University of California at Santa Cruz. A superior research scientist and educator, the breadth of her activities and interests were perhaps unnoticed by many because of her modesty and generosity. To those in the field she maintained an international reputation as a hydrogeologist with recognized expertise in diverse topics including arid basin hydrology, quantitative analysis of flow through karst aquifers, moisture and contaminant transport through unsaturated soils, and the hydrogeology of subduction zones.
