| Session Description | In Asia and Oceania regions, sediment-related issues such as catchment erosion, the loss of fertile land and reservoir siltation and the associated downstream geomorphological and ecological consequences of increased or decreased sediment supply are becoming increasingly important to manage. Identification and quantification of sediment sources and comprehension of erosion, transport and depositional processes of sediments are critical to target these issues and improve catchment health. The sediment tracing field has largely focussed on the catchment-scale movement of sediments; however, a growing number of researches have studied marine sediments as records of sediment movement and offshore delivery, which broaden horizons of sediment tracing research. Approach and technique of sediment tracing across the land and the sea have been evolving significantly, including settings of the catchment to be studied, statistical treatment of tracer signals and consideration of tracer characteristics in transport and deposition. A broad range of papers are invited to this session to present and share recent results and progress of studies related to sediment tracing across the catchment to the sea. Approach, technique and application will be sub-divisions of the session. |
