| Session Description | Throughout the Austral-Asian region, extreme erosion processes are common due to high and/or intense rainfall, mountainous terrain, expanding anthropogenic pressures, tectonic activity, soil conditions, and geological history. While these span the gambit from sheet erosion to gully erosion to mass wasting processes, herein we focus on extreme occurrences of individual or combinations of erosion types. These extreme events may manifest during an individual storm or as the result of cumulative precipitation. Presentations may include results from field investigations, experimental research, remote sensing studies, or modelling, including combinations of these. Interdisciplinary perspectives are encouraged, including incorporation of socio-economic factors and impacts. We invite contributions from all areas of soil science, hydrology, geosciences, engineering, and ecology. Specific themes we wish to promote include: - Extreme surface erosion processes, including gully erosion - Erosion and sedimentation in river channels and floodplains - Landslide erosion - Sediment fingerprinting to identify erosion sources - Wind erosion - Sedimentation in reservoirs and water quality issues - Climate change and the role of extreme hydro-climatic events on erosion processes - Different modelling approaches to estimate runoff and soil erosion processes - Small-scale experimental studies on erosion and runoff processes - Recent progress in new methods and technologies of quantifying erosion including remote sensing, geographic information systems, photogrammetry, LiDAR, and TLS - Understanding the hydrological and sediment connectivity throughout catchments, including methods, process-based concepts, and quantification techniques. This session will be a venue to communicate findings from different perspectives and promote debate amongst geoscientists, soil scientists, and hydrologists. We wish to promote an integrated, conceptual framework for sharing expertise developed at local and regional scales to better understand the hydrological processes involved in soil erosion to foster better management of soil and water resources in the Austral-Asian region. |
