Small-scale study of Debris-Flows Interactions with a Lateral Debris Basin and Crossings: The Manival Torrent case study

Small-scale models are useful tools to study the interactions between debris flows and structures channels. modelling of remains however complicated because complex rheology scaling challenges these geophysical processes. An on-going a basin downstream channel where two fords bridge located is presented in this extended abstract. The studied torrent Manival catchment, near Grenoble France. We present catchment features, scientific questions studied, some preliminary calibration results describing mixtures used model as well from three debris-flood debris-flow runs. In essence, highlighted that structure enable large share bedload transport pass downstream. Debris can be more or equally trapped depending on their which controls surges dynamics deposition slope basin.
