Sediment budget monitoring of debris-flow and bedload transport in the Manival Torrent, SE France
Steep mountain catchments typically experience large sediment pulses from hillslopes which are stored in headwater channels and remobilized by debris-flows or bedload transport. Event-based sediment budget monitoring in the active Manival debris-flow torrent in the French Alps during a two-year period gave insights into the catchment-scale sediment routing during moderate rainfall intensities w...
متن کاملMonitoring the propagation of a debris flow along a torrent
The results are presented of a field experiment on debris flow monitoring that were obtained in the summer of 1996 in a small mountain torrent in the Italian Alps. A network of seismic detectors was placed about one kilometre upstream of some previously existing gauging stations equipped with ultrasonic devices. In June and July two debris flows occurred, which were recorded both by the seismic...
متن کاملDebris-flow activity in abandoned channels of the Manival torrent reconstructed with LiDAR and tree-ring data
Hydrogeomorphic processes are a major threat in many parts of the Alps, where they periodically damage infrastructure, disrupt transportation corridors or even cause loss of life. Nonetheless, past torrential activity and the analysis of areas affected during particular events remain often imprecise. It was therefore the purpose of this study to reconstruct spatio-temporal patterns of past debr...

15 صفحه اولSediment Transport in Unsteady Flow Conditions
Sediment transport under unsteady flow condition is studied experimentally. In the first step, sediment transport under different steady flow conditions was measured and an empirical equation was derived for its calculation. In the next step, two continuous and three stepwise hydrographs were generated in the flume, and their sediment transport rate was measured. The continuous hydrographs were...
