英文摘要	Urban flooding is the most frequent and damaging of all natural hazards, including those caused by dam breaks. One flood mitigation and control method is using flood risk maps to provide helpful information. This study aims to map the three parameters of urban flooding: exposure, vulnerability, and flood risk following a hypothetical failure of the Gazelles fountain dam (Manbaa Al-Ghozlan) in the city of Biskra (40 km downstream of the dam) through a multi-criteria decision-making process (MCDM). Six influencing factors were used for the vulnerability assessment: land use, distance from significant watercourses (Oued), distance from drainage accumulation, elevation, population density and distance from main roads. The influence of each factor was examined by attributing weights to each criterion according to its impact on urban flood vulnerability. A flood risk map that can evaluate the extent of damage and its economic implications is made based on hazard and vulnerability maps. Based on pixel values, the flood risk map has been divided into four classes: very high, high, moderate and low. The results indicate that more than 63% of the area is at high risk. The water depth in these areas may exceed 10 m in the case of dam failure. The constructed flood risk map is an informative tool to assess critical damage for decision-makers in arid and semi-arid areas.
