Landslides and their hydraulic effects are studied by numerical and experimental means. A two-dimensional model based on Navier-Stokes equations has been developed considering the sediments and water as a mixture. A Bingham law written in effective stress and an erosion-diffusion law at the water-sediment interface have been introduced into the model. Laboratory experiments consisting in the sliding of a block, a coarse gravel and a fine sand have been carried out. The results are compared with the numerical model. These experiments show the importance of sediment rheology and interstitial pressure in slide velocity and water wave generation.
