This collection of papers is the proceedings of the 7th International Synosium on Water Tracing in Portoroz/Slovenia from 26-31 May 1997. They address a number of topics in hydrology tracing techniques including: protection of natural resources against pollution; the use of natural and artificial tracers to help to assess contaminant transport in surface waters; and aquifer parameters and modelling.

Tracers in Hydrology and Water Research is a comprehensive overview of the application of natural and artificial tracers in hydrology and environmental research. Taking a unique approach by providing the reader with a systematic and state of the art description of natural and artificial tracers, the book also covers key analytical techniques and applications, and modern tracer methods in the context of systematic hydrology. Tracers have become a primary tool for process investigation, qualitative and quantitative system analysis and integrated resource management. This book will outline the fundamentals of the subject, and examine the latest research findings, clearly showing the entire process of tracer application through the inclusion of numerous integrated case studies. As many techniques derive from different scientific disciplines (chemistry, biology, physics), the effort of compilation and integration into modern hydrology and environmental science research and application requires substantial continuity and experience, which certifies this group of authors. This book will be an invaluable reference not only for students and researchers within the field of Hydrology and Hydrogeology but also for engineers and other tracer techniques applying users.

Environmental Tracers in Subsurface Hydrology synthesizes the research of specialists into a comprehensive review of the application of environmental tracers to the study of soil water and groundwater flow. The book includes chapters which cover ionic tracers, noble gases, chlorofluorocarbons, tritium, chlorine-36, oxygen-18, deuterium, and isotopes of carbon, strontium, sulphur and nitrogen. Applications of the tracers include the estimation of vertical and horizontal groundwater velocities, groundwater recharge rates, inter-aquifer leakage and mixing processes, chemical processes and palaeohydrology. Practicing hydrologists, soil physicists and hydrology professors and students will find the book to be a valuable support in their work.

This book is a printed edition of the Special Issue "Environmental Tracers" that was published in Water
