The geomorphological, surficial and geochemical processes and conditions of rivers require a tailored set of strategies and programs to successfully clean up contaminated river reaches. The primary purpose of this book is not only to provide students and professionals with an introductory understanding of fluvial geomorphic principles but also to explain using a process oriented approach how these geomorphic principles can be integrated with geochemical data to cost-effectively characterize, assess and remediate contaminated river systems. Numerous case studies from North America and many other parts of the world are included. Audience: Upper level undergraduate and graduate students in geoscience, engineering, environmental science, geography, geochemistry, toxicology, and soil science studying the means to assess, remediate or restore contaminated streams and rivers. It also serves as a reference book for professionals who are working on contaminated aquatic systems, particularly rivers contaminated by trace metals. "River contamination is a problem of global significance. This book provides a comprehensive and highly readable review of the role of fluvial geomorphic processes in understanding and predicting the dispersal and fate of contaminants in aquatic environments. Aimed at both students and professionals it forms an excellent introductory text to this rapidly developing field, especially in river basins experiencing rapid environmental change." Mark G. Macklin, University of Aberystwyth, UK "This excellent book clearly and graphically explains the geochemical and geomorphological principles influencing the contamination of river systems, and cost-effective methods for contaminated river assessment and remediation. I shall certainly be recommending it to all of my students and colleagues." Karen Hudson-Edwards, Birkbeck, University of London, UK

This book takes an in-depth look at the theory and methods inherent in the tracing of riverine sediments.  Examined tracers include multi-elemental concentration data, fallout radionuclides (e.g., 210Pb, 137Cs, 7Be), radiogenic isotopes (particularly those of Pb, Sr, and Nd), and novel (“non-traditional”) stable isotopes (e.g., Cd, Cu, Hg, and Zn), the latter of which owe their application to recent advances in analytical chemistry. The intended goal is not to replace more ‘traditional’ analyses of the riverine sediment system, but to show how tracer/fingerprinting studies can be used to gain insights into system functions that would not otherwise be possible. The text, then, provides researchers and catchment managers with a summary of the strengths and limitations of the examined techniques in terms of their temporal and spatial resolution, data requirements, and the uncertainties in the generated results. The use of environmental tracers has increased significantly during the past decade because it has become clear that documentation of sediment and sediment-associated contaminant provenance and dispersal is essential to mitigate their potentially harmful effects on aquatic ecosystems. Moreover, the use of monitoring programs to determine the source of sediments to a water body has proven to be a costly, labor intensive, long-term process with a spatial resolution that is limited by the number of monitoring sites that can be effectively maintained. Alternative approaches, including the identification and analysis of eroded upland areas and the use of distributed modeling routines also have proven problematic. The application of tracers within riverine environments has evolved such that they focus on sediments from two general sources: upland areas and specific, localized, anthropogenic point sources. Of particular importance to the former is the development of geochemical fingerprinting methods that quantify sediment provenance (and to a much lesser degree, sediment-associated contaminants) at the catchment scale. These methods have largely developed independently of the use of tracers to document the source and dispersal pathways of contaminated particles from point-sources of anthropogenic pollution at the reach- to river corridor-scale. Future studies are likely to begin merging the strengths of both approaches while relying on multiple tracer types to address management and regulatory issues, particularly within the context of the rapidly developing field of environmental forensics.
