WebA landslide is a mass movement of material, such as rock, earth or debris, down a slope. They can happen suddenly or more slowly over long periods of time. When the force of gravity acting on a slope exceeds the resisting forces of a slope, the slope will fail and a landslide occurs. External factors can lead to landslides happening, including: WebDebris flows are more likely to occur when excess water is present, whether this is from rainfall, overland flow, or damaged culverts, water pipes etc. Debris flows also occur when the toe (bottom) of a slope is removed, whether this is from erosion or excavation for construction. To prevent debris flows, we should minimize clear-cutting trees ... WebDebris Flows. Debris flows are rapidly moving, extremely destructive landslides. They can easily travel a mile or more, depending on the terrain. They typically contain boulders and logs transported in a fast-moving soil and water slurry down steep hillsides and through narrow canyons. A debris flow moves faster than a person can run. twin breasor ii
