Like many metropolises around the world, Algerian towns and cities are particularly vulnerable to the risk of flooding.
This threat has increased in recent years, exacerbated by global warming and other converging factors. The vulnerability of Algerian cities, where major human, material and environmental issues are concentrated, now appears to be increasing in the face of the growing threat of such natural hazards.
Take the town of Batna in Algeria, for example. Situated on a gently sloping site, it is crossed by two major rivers and surrounded by very uneven terrain. This geographical conFigureuration has earned it the status of a ‘base city’, making it particularly vulnerable to the recurring risk of flooding, and adding to the impermeability of its soil.
With this in mind, our research first set out to elucidate the dialectical relationship between the rapid urbanisation of the Algerian city of Batna in recent years and the risk of flooding. Secondly, our study set itself a pragmatic objective: to identify precisely defined solutions for each area of the city, while avoiding a ‘clean slate’ approach.
