Résumé

The role of preferential water flows in triggering landslides is complex and ambigu-ous. First of all, preferential flow is well known to increase groundwater recharge and decrease the time delay between rain event and landslide response. Secondly, fissures can also drain landslide areas, lowering the groundwater table locally. On the mechan-ical part, fissures reduce the overall mobilised shear strength.
