This book is the proceedings of an international symposium held during the joint meeting of the International Association of Meteorology and Atmospheric Physics (now called the International Association of Meteorology and Atmospheric Sciences) and IAHS at Yokohama, Japan, in July 1993.
The objective of the symposium was to provide a forum for discussions on the use of tracers to improve the understanding of hydrological processes, with emphasis on issues of scale, for both time and space. Consequently, papers varied in subject from investigations of chemical signatures (sources) of atmospheric deposition to residence times and transport in groundwater. One exception is the keynote paper by Y. Yurtsever & L. Araguas Araguas of the International Atomic Energy Agency which provides an excellent overview of the Agency's involvement in environmental isotope applications in hydrology.
The remaining papers focus on studies of hydrological processes in which tracers were used. The papers are grouped in five topics: Watershed processes (including streamflow generation and geochemical reactions or hydrochemical interactions along hydrological pathways; Groundwater (including isotopic, chemical and temperature techniques for processes of flow and transport in both the unsaturated and saturated zone); Surface water (including both lakes and rivers); Groundwater and surface water interactions; and Sediment (including identification and quantification of sources for water- and air-borne sediment).
