Development of a Flood Risk Prevention Plan: The Case of the Tlemcen Agglomeration (Algeria)

Abstract

Floods are among the most devastating and recurrent natural disasters worldwide. They occur when water levels exceed the retention capacity of soils, watercourses, or infrastructure, causing overflows and significant damage. In Algeria, as in many regions across the globe, flood risks are a major concern, threatening lives, property, and the environment.

The causes of floods are numerous and complex. They can be triggered by extreme weather events such as heavy rainfall, tropical storms, or rapid snowmelt. Additionally, human factors such as unplanned urbanization, deforestation, and climate change often exacerbate these risks by altering natural ecosystems and increasing the vulnerability of populations.

In the face of these challenges, flood risk management is of paramount importance. It encompasses a range of preventive, preparatory, and responsive measures aimed at reducing the impact of floods and protecting exposed communities. These measures include the implementation of early warning systems, the construction of effective drainage infrastructure, the execution of emergency evacuation plans, and raising awareness among the population about safety behaviors during floods.

In this context, this article explores the challenges posed by floods in Algeria, examines the specific risks associated with these phenomena in the country, and proposes strategies and solutions for effective crisis management. By focusing on prevention, preparation, and response to floods, it aims to contribute to the resilience of Algerian communities in the face of these persistent natural threats.
