SLOWMOVE – A numerical model for the propagation of slow-moving landslides: a 1D approach and its application to the analysis of the Valoria landslide (Apennines, Italy)
Understanding the behavior of landslides often starts with a numerical simulation that accurately accounts for observed
physical processes. This research proposes a method for the implementation of the dynamic SLOWMOVE
model to a high-mobility, moderate velocity earth flow located in the northern Apennines.
The Valoria landslide is 3.5 km long earth slide- earth flow that resumed activity in 2001. Landslide materials
comprised of disaggregated Flysch, Marl and Claystones are mainly transported as earth slides in the upper slope,
and as earth flows in the main track. Repeated acceleration events lasting several weeks occur seasonally since
2001 reactivation. During events it can reach velocities of about 10 m per hour with a cumulative displacement of
hundreds of meters. Through this intermittent activity, more than ten million cubic meters have been transferred
down-slope since 2001, changing significantly and several times the morphology of the slope
