Isotope techniques in groundwater hydrology 1974, Vol. I. Proceedings of a symposium

This symposium, held in Vienna on 11-15 March, 1974, was the fourth on the subject of isotope hydrology organized by the International Atomic Energy Agency. However, this one was limited to groundwater hydrology in view of the general increase of interest and activity in isotope hydrology since the previous meeting in 1970. The proceedings of this symposium are a good indicator of the present world status of these techniques. Thus one notes that many of the studies are in the developing areas of the world. Furthermore, there has been a shift to using these techniques as an additional applied tool in specific problems of development of water resources. Examples of such applications also give evidence of the closer collaboration between isotope specialists, who originally developed the methods, and hydrogeologists and geochemists. It is hoped that these proceedings will contribute to a wider appreciation of the potential use of isotope techniques to hydrological problems associated with the development of groundwater for agriculture, community water supply and industry
