Abstract

The study aims to outline the flood potential of a mountainous area, in the context of simulating flooded areas, GIS techniques being essential in determining the spatial and probabilistic impact of this type of hydrological phenomena. The resulting modeling highlights the floodplains and the probabilities of manifestation of 0.1 and 1%. The localities situated downstream of the Tulgheș hydrometric station are at risk, but the current methodology generates cartographic materials at an optimal resolution, initially for highlighting and later for the amelioration of vulnerable areas and the effective reduction of damages following a possible flood.
