2007 Ground Water Summit

Wednesday, May 2, 2007: 9:20 a.m.-10:20 a.m.
Ruidoso (Albuquerque Convention Center)
Geophysics for Karst and Fractured Rock
Encroaching urbanization and changes in weather patterns are stressing ground water supply and our ability to protect it. The inevitable result is an increased demand for better knowledge of the subsurface hydrogeological processes controlling the flow and storage of ground water. In the western U.S., ground water is inextricably connected to fractured rock and cavities. Ground waterflow path delineation using geophysical methods is advancing at a rapid pace as innovations in data acquisition, processing, and visualization are implemented. The net result is a better understanding of subsurface site conditions which, in turn, allows for improved development and management practices. This theme is illustrated in this session through the presentation of case histories and information on recent technological advances.
