Although gravity is the driving force of mass wasting, it is impacted mainly by the slope material’s strength and cohesiveness as well as the amount of friction acting on the material. If friction, cohesion, and strength (collectively known as the resisting forces) are high in a given area,...
What causes a landslide? Almost every landslide has multiple causes. Slope movement occurs when forces acting down-slope (mainly due to gravity) exceed the strength of the earth materials that compose the slope. Landslides can be triggered by rainfall, snowmelt, changes in water level, stream er...
The use of vegetation as a Nature-based Solution (NbS) for shallow landslide risk reduction is receiving increased attention in the scientific community. Vegetation can contribute to slope stability through both hydrological and mechanical processes. Slope stability models are valuable tools to quantify ...
A mass movement can be as small as some rocks and debris you kick down a small incline or as big as the 1980 landslide set off by the eruption of Mount St. Helens. There are many kinds of mass movements categorized by the type of material involved, the way they moved and how fast ...
mechanism, existing models only consider the rubbing of the bed surface by a shear stress parallel to the slope. However, we observe that a ploughing-type erosion occurs due to normal stresses acting on the bed in the flow direction. The additional ploughing explains why beds which are ...
Furthermore, contrary to what is often assumed (Voight, 1988; Rose and Hungr, 2007), landslides can also be forecasted when external forces are acting on them, as demonstrated by Intrieri and Gigli (2016), who relaxed this assumption. The full potential of such methods is still to be ...
FAST LANDSLIDES TRANSITION FROM CREEPING ... CONCLUSIONS AND MAIN CONT... Classical methods (limit equilibrium) of slope stability provide a numerical scale (the safety factor) to the proximity of failure. However, failure events are often unavoidable, especially in natural environments. In fact, ...
Landslides in VM are very well-preserved features that captured the planet surface at the instant of failure; also because of this, the visible landslide deposits often show the superposition of multiple events. Landslide age is defined in a relative way based on the appearance of the main ...
whereτis the shear strength;σnis the normal stress acting on the discontinuity surface;φris the residual friction angle, which was assumed equal to 31° [17]; andωis the inclination of large-scale undulations along the sliding direction, measured on roughness profiles from the point cloud....
