This book represents a new "earth systems" approach to catchments that encompasses the physical and biogeochemical interactions that control the hydrology and biogeochemistry of the system. The text provides a comprehensive treatment of the fundamentals of catchment hydrology, principles of isotope geochemistry, and the isotope variability in the hydrologic cycle -- but the main focus of the book is on case studies in isotope hydrology and isotope geochemistry that explore the applications of isotope techniques for investigating modern environmental problems.
Isotope Tracers in Catchment Hydrology is the first synthesis of physical hydrology and isotope geochemistry with catchment focus, and is a valuable reference for professionals and students alike in the fields of hydrology, hydrochemistry, and environmental science. This important interdisciplinary text provides extensive guidelines for the application of isotope techniques for all investigatores facing the challenge of protecting precious water, soil, and ecological resources from the ever-increasing problems associated with population growth and environmental change, including those from urban development and agricultural land uses.

Carol Kendall is a research hydrologist in the Water Resources Division of the U.S. Geological Survey. Since 1990, she has been chief of the "Isotope Tracers of Hydrologic and Biogeochemical Processes" project in Menlo Park, California. The purpose of this research project is to develop new methods, concepts, and applications of environmental isotopes to solve problems of national importance. She received her B.S. and M.S. in Geology from the University of California (Riverside), and her Ph.D. in Geology from the University of Maryland. Her main background is in isotope hydrology and aqueous geochemistry. Kendall is coordinator and main instructor of the 5-day Isotope Hydrology training course taught almost yearly for the USGS, and frequently teaches other short-courses. The main focus of isotopic heterogeneity in shallow systems on determining recharge mechanisms, tracing sources and reactions of nitrate in surface waters and groundwaters using oxygen and nitrogen isotopes, and applying a multi-isotope (O,H,C,N,S,Sr) approach to studying watershed hydrology and biochemistry. She has recently become fascinated with "isotope biomonitoring" --the idea of using isotopes of organisms as integrators of environmental conditions at the landscape-scale, including providing information about sources of nutrients in human-impacted environments.
