Landslide is a natural phenomenon that poses a threat and danger to humans due to the amount of damage it can cause and the different factors that can trigger it. The watershed of Oued Laou, Morocco, a part of the central Rifaine mountain chain, is a basin that is highly threatened by landslides as it is characterized by rugged terrain with steep slopes (25%) and significant height differences. The study and prevention of this phenomenon in the area is not easy as it requires a large amount of data and access to areas whose topography is difficult. The present study therefore employs a combination of conventional statistical methods and modern digital technologies using the analytic hierarchy process and geographic information system to enable mapping of landslide susceptibility zones in the area.
