Focuses on understanding of the processes of erosion and sediment production in a world that is increasingly affected by anthropogenic activities. Four keynote papers open this volume, and the remaining 50 contributions are grouped by theme: Dynamic processes of erosion and sediment transport in fluvial systems; Impacts of climate change and human activities on erosion and sediment yield ; Modelling erosion and sediment yields ; Mountain hazards and debris flows ; Monitoring and tracing methodology.The International Association of Hydrological Sciences is the world"s premier member-based organization promoting the study and practice of Hydrology. Our books are authored, edited and produced at the highest level of quality, with the most current and thorough research. Our publications and our work advance the science and the professional practice of Hydrology in a variety of Science and Engineering fields around the world. The areas that we publish in include: -Ground water -Surface water -Snow and ice hydrology -Drought and desertification -Runoff modelling -Watershed -Remote sensing -Water quality -Water resources and management -Ecohydrology/hydro-ecology -Erosion and sediment -Tracer hydrology
