Description :
In this study, a 2 step approach has been applied. First, in order to find the most relevant flooding areas, a one dimensional hydraulic model HEC-RAS has been used. Then, in a smaller area, a 2D hydraulic model shows the depth and duration of inundation, as well as the velocities and direction of the water flow. These parameters, when combined with the information on the height of buildings and their value, can give an approximation of flood costs in various different scenarios. The spatial distribution of the time that elapses from the dike breach and the moment at which a given point is inundated can be transformed into a cartographic representation, and as a propogation map can be used for defining the risk in the flood zone.
