“…Several studies have been carried out with the aim of generating flood risk maps based on hydrological and hydraulic simulation (Astite et al 2015;Yamani et al 2016;Abdessamed andAbderrazak 2019 andHafnaoui et al 2020) or hydrogeomorphological approach (Cheikh lounis et al 2015;ZaÏri 2018;Mimouni et al 2019;Bourenane et al 2019). By using PLUTON as a hydrological model and HecRas for flood simulation, Astite et al (2015) delimitated flood risk areas in El Harrach river, the most important in Algiers city.…”

Floods are frequent hazard in Algeria. They cause severe casualties, destroy infrastructures, and impair economies. In the past decades, Algeria experienced devastating floods. The dominant type of occurring floods are flash floods, which tend to be not well documented and studied in Algeria. This chapter presents a brief introduction to the flood phenomena within the Algerian climatic and management context, based on databases, scientific publications, and local technical reports. Existing studies about floods are reviewed. It also provides an analysis of the most disastrous floods that occurred in the past decades. Of the most noteworthy flash floods, a highlight of the Bab El Oued flash flood occurring in a heavily urbanized setting and the M’zab Valley flash flood, which took place in a UNESCO World Heritage Site. The monitoring network in Algeria is presented and data availability is discussed. The implementation of the first forecasting and early warning system are also presented. Different aspects of flash floods were presented including the effect of the increase of urbanization, the influence of climate change and the adopted strategies of flood risk management. Heavy and increasing urbanization and population growth increased the flood vulnerability and this trend must be mitigated.
