Innovative Technologies to Monitor and Model Sediment Entrainment and Transport in Geomorphic and Hydrogeological Hazardous Flows

Session ID#: 160787

Session Description:
In addition to being fundamental components of all geomorphic systems (including fluvial, aeolian, coastal, hillslopes and glacial), sediment entrainment and transport are strongly linked with hydrogeological hazards. Sediment concentration and dynamics change the rheology, propagation and impact of hazardous flows such as landslides, floods, volcanic eruptions, and tsunamis. Recent developments have provided new opportunities for measuring sediment entrainment and transport in the field and new ways to represent them in both physical laboratory and numerical models. These include seismic and acoustic monitoring, 3D imaging (e.g. CT and MRI scanning), deployment of sensors such as accelerometers, replication of field topography using 3D printing, use of luminescence as a sediment tracer, discrete, SPH and Lattice Boltzmann numerical modelling, and new statistical approaches.

Contributions are welcomed from all areas of geohazards and geomorphology that use those methods for monitoring and modelling all types of sediment transport, or that showcase their application.
