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.

Abstract


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.
