A North Atlantic Treaty Organization (NATO)-funded Hydrogeophysics Advanced Study Institute (ASI), held at the Trest Castle in the Czech Republic in July 2002, brought together for the first time a leading group of researchers and students active in this emerging discipline. Approximately 60 hydrogeologists interested in incorporating geophysical data into their subsurface characterization problems, and geophysicists involved in subsurface hydrogeological characterization, attended the institute.
Hydrogeologists and geophysicists often use different yet complementary approaches to investigate subsurface problems. The new discipline of hydrogeophysics strives to reconcile information obtained using both hydrogeological and geophysical approaches to improve our understanding of subsurface parameters or processes. The NATO ASI was held to assess the state of the discipline, and to review recent research breakthroughs and obstacles associated with hydrogeophysics.
