The paper presents a consistent micro-scale flood risk analysis procedure, relying on detailed 2D inundation modelling as well as on high resolution topographic and land use database. The flow model is based on the shallow-water equations, solved by means of a finite volume scheme on multiblock structured grids. Using highly accurate laser altimetry, the simulations are performed with a typical grid spacing of 2m, which is fine enough to represent the flow at the scale of individual buildings. The methodology is first described, both in terms of hydraulic modelling and evaluation of people and assets vulnerability. The analysis scale of the procedure enables its development following an object-oriented approach. Finally, the applicability of the procedure is demonstrated through a case study for which three different protection measures are evaluated. Detailed analysis of these measures highlights significantly different influences from those measures on the risk curves. [less ▲]
