FLASH FLOODS IN ALGERIA

B. REMINI

Abstract


Flash floods in Algeria, this paper discusses the characteristics of these new floods. In reality, these floods are of Saharan origin and are caused by torrential rainfall, the equivalent of 3 to 12 months falling between 24 hours and 72 hours. In recent years, these floods have moved toward northern Algeria and even in certain countries of the Mediterranean basin. In addition to the brutality and aggressiveness, these flash floods are characterized by the significant quantities of fine particles transported, which reflect the resizing of the hydrographic network and the digging of new gullies in the watershed to evacuate the large masses of water transported. by these floods. Rainwater evacuation systems (sanitation networks and flood spillways) are currently undersized in the face of these new floods. Flash floods are a little-known subject that requires in-depth studies to predict them.
