This book, which contains 28 chapters grouped into 5 parts, reviews the major achievements recently made in soil erosion and sediment redistribution study and management as well as the future requirements. The chapters included represent the variety of temporal and spatial scales of operation, from the modelling of dynamic event-based processes to the annual monitoring of a site to determine longer term trends. The chapters also explore some of the many environments in which erosion and sediment redistribution occur, and indeed the unique controls that these environments may exert on geomorphological functioning. Part 1 serves as the introduction of the topics to be discussed and provides an overview of the succeeding chapters. Part 2, which consists of chapters 2-12, uses a variety of contrasting techniques to measure soil erosion on land and sediment flux in rivers, including deposition within lakes and reservoirs. They have been broadly arranged so as to illustrate the differences and similarities in the techniques used to measure soil-sediment transfers from land to rivers to lakes. The chapters in part 3 (chapters 13-20) explore some of the common advantages and problems associated with modelling approaches and new developments within the science. The chapters recommend refinements and methods to improve the availability and reliability of data, parameterization of key factors and approaches for modelling components previously neglected in soil erosion and sediment studies. In part 4, the chapters (21-27) look at the effect of various land management practices on the generation of erosion and sediment and the implications for receptors in forested, agricultural and urban areas in temperate and tropical environments. The last chapter, on the other hand, provides a summary of the topics discussed and relates these in a broader framework of soil-sediment-water systems and attempts to identify future research needs to assist the science in addressing the requirements of catchment managers and policy-makers.
