Erosion fluviatile et mutations morphométriques de l’Oued Bouregreg dans le secteur de Maaziz (Plateau central, Maroc)

Abstract

This study focuses on analyzing the fluvial erosion process and the resulting morphometric changes in the Bouregreg Riverbed at Maaziz. The results indicate intense erosion, particularly during high-flow floods, manifesting as undercutting, sliding, and bank collapse. In addition to this erosive activity, lateral tributaries and alluvial fans also contribute to fluvial metamorphosis. Between 1970 and 2020, the riverbed underwent slight morphometric modifications, characterized by the preservation of the same fluvial style, despite local changes such as channel narrowing and the development of gravel bars.
