[en] The main objective of the present paper is a description of two effective numerical 2D
models to be used as strategic tools in the process of flood risks assessment and
mitigation. The first one is a model for hydrodynamics simplified according to the
diffusive assumption while the second one is a complete model based on the shallow
water equations. Each of them is solved with an efficient numerical technique (including
implicit time integration schemes and GMRES linear solvers) maximizing the
convergence rate towards a steady state. A practical case study, for which a high
resolution Digital Elevation Model exists, will be presented. The study shows the
consequences on structures of a new construction in the floodplain in terms of inundation
and erosion.
