Abstract
Urban vulnerabilities must be studied and assessed to
make cities more resilient to floods. This study aimed to assess
the urban vulnerability of El Bayadh city, located in the west of
Algeria, to floods and to identify flood-prone areas. Using the
Hierarchical Multi-criteria Analysis (HMA) method, a set of
criteria was proposed such as population density, housing
typology, type of equipment, and road network to measure the
overall fragility of the study area. The Geographic Information
System (GIS) was used to translate the obtained results and
develop the global vulnerability map. The most important results
were: 5.6% of the study area had an extreme vulnerability,
7.97% high vulnerability, 8.5% medium vulnerability, and
77.87% low vulnerability. The results of this study can be used
as a tool to assist local authorities during decision-making
regarding flood danger assessment
