Résumé
In this paper, we focus on medium/small-scale landslides of the Middle Kali Gandaki (KG) valley, where the river cutsacross the >8000 m high peaks of Dhaulagiri and Annapurna Himal (the deepest gorge in the world). The study zone is very prone to geomorphic instability (very steep slopes, litho-units of varying resistance, the highest amount of rainfall in the Nepal Himalaya; Dahal and Hasegawa 2008). Mountainslopes are either made of rocky spurs with segments exceeding 70° in slope angle, or unstable, debris-covered slopes (
