Due to the increase of the frequency and severity of hydrik risk phenomena, applying GIS techniques for spatial analysis became indispensable for the identification of the most vulnerable areas to floods and flash-floods. In this study, a proper methodology was used to estimate built areas vulnerability to flash-floods within Pănătău river basin, which is located in a very exposed area. Thus, the buildings vulnerability index (BVI) was defined and calculated by including the following components: the Flash Flood Potential Index (FFPI) and the buildings density within the built-up area (D). The calculation of BVI was based on multiplying the standardized values of these two components. The results highlighted a high and very high vulnerability to flash-floods, on almost 13% of the total area. According to the spatial distribution of BVI values, within each village, the most vulnerable surfaces are located in Pănătău and Sibiciul de Jos, which is also attested by data from the National Romanian Water Administration. On the other side, Lacu cu Anini village is the less vulnerable.
