Comprehension of debris-flow / structure interaction

Progress in the comprehension of debris-flow / structure interaction, mainly development of a new 3D numerical model able compute transitory flows close to the structure and validation in the laboratory.

The main result is a new numerical model based upon the smoothed particles hydrodynamics technique and which has been developed for the purpose of studying debris-flow / structures interactions. This 3D unsteady model makes it possible to compute flow close to structures and give a precise description of its characteristics in one hand and of the pressures applied by the flow to the structure in the other hand.

This model has been partly validated by comparison to laboratory experiments. The expected benefit is to be able after further research, to precisely compute the pressures applied to structures while for now, only very rough approaches exist. The expected benefit is new methods and rules for the design of check dams for example.
