GM6.1The geomorphic significance of mass wasting processes
|Convener: Francesco Brardinoni|
Mass wasting processes are prominent geomorphic players in the evolution of mountain drainage basins. They dominate sediment transfer and affect channel morphodynamics of steep, low-order streams. Currently, no quantitative expression that connects mass wasting processes and forms has been proposed, nor any has been tested and applied in physically-based, spatially-distributed models.
This session seeks quantitative contributions on the geomorphic significance of mass wasting processes, including debris flows, landslides, and rock falls. Topics of particular interest include but are not limited to: the spatial organization of mass wasting initiation and deposition in relation to morphometry, land use, and lithology; magnitude-frequency relations; rates of sediment production and transfer; colluvial sediment dynamics on sedimentary linkages such as fans and cones; the geomorphic signatures of triggering mechanisms; and impacts on channel morphology and fluvial transport.
Studies that integrate multiple techniques of data collection and analysis (e.g., field-based measurements, remotely-sensed inventories, GIS-based analysis, and modelling efforts) across different temporal scales (e.g., through real-time monitoring, dendrochronology, or cosmogenic nuclides) are particularly welcome.
