Abstract :	[en] Dam break flow modelling is a major field of research. In order to enable risk analysis in the downstream valleys of dams, 2D numerical simulations are of prime interest. These are based on the conservative set of shallow water equations. Beyond their numerical implementation, the challenge of the computation relies on the ability to handle very huge sets of high-precision data, in order to get the highest possible accuracy, whereas the computational time must remain realistic for simulations carried out on real valleys topography. In this paper, a simulation on about 2 500 000 cells is presented. Particularly, the results are compared and discussed regarding especially the exploitation of landuse data for the roughness. Beyond the examples of validation, the relevance of the developed methodology appears to be essential in the framework of risk analysis.
