Check dams are a potentially effective instrument for planning of hydrological risks and soil conservation. Cross structure sequences have been used in numerous areas in the world to control flooding, recharge aquifers and stabilise mountain streams, gullies and high-gradient ephemeral channels. Nevertheless, it is little known of the effectiveness of check dams and their morphological effects. This book is an attempt to compile different based-field and laboratory research works in torrential head water areas. Bed stability variations will be investigated according to check dams types, bedrock control, bed slope, channel roughness, lateral sediment input, and highly variable sediment transport capacity. Though the main purpose of check dams is to stabilise the channel bed and diminish the boundary sheer stress reaching a minor longitudinal slope, they can reduce the volume of channel-stored material favouring local scour processes downstream and occasionally destabilise the hill slopes upstream.

This book focuses on soil and water conservation at global scale. It is a serious environmental problem that will threaten the socio-economic well-being of the majority of global population in future. The book examines the current situation of land degradation in multiple regions of the world and offers alternative approaches to solve the problems through sharing advanced technologies and lessons learned. It provides comprehensive assessment on characteristics, level and effect of degradation in different regions. It’s a highly informative reference both for researchers and graduate students.

The book contains papers presented at the fourth in a series of biennial International Conferences dealing with the Monitoring, Simulation, Prevention and Remediation of Dense and Debris Flow. The papers deal with erosion and slope instability, sediment transport, debris flow and debris flood data acquisition, debris flow phenomenology and laboratory tests, using the most advanced, state-of-the-art methodologies in monitoring, modelling, mechanics, hazard prediction and risk assessment of debris flow phenomena.

This book provides a detailed overview on methods used for the dating of past torrential activity on fans and cones and fosters the discussion on the impact of past and potential future climate change on torrential processes. The book has a clear focus on the practical applications of these methods, complemented by case studies. The limits of each dating method in case of excessive natural and human interventions on fans and cones are shown.

This book provides an introduction to a fairly new approach to natural resources management practice entitled ecohydrology-based landscape restoration. Ecohydrology-based landscape restoration integrates landscape restoration practices with ecohydrology science and principles in order to help address the limitations of current management practices in developing countries. Focusing on both the theory and practice of implementing new management practices, the book includes conceptual designs and practical demonstrations for a variety of sites, including hillsides, farmlands, gullies, riparian buffers and wetlands, while also drawing on field research conducted in Ethiopia. The book puts forward principles for improving current practices, which include the better integration of hydrological and ecological concerns, the greater involvement of local communities, the adoption of indigenous practices, the establishment of green and semi-grey infrastructure as an ecohydrological systemic solution and the necessity of taking an adaptive approach to managing landscapes. This book will be of great interest to students and scholars of water resource management, ecohydrology and landscape restoration as well as professionals involved in the restoration of landscapes in developing countries.
