Models
We define landslide models as conceptual entities, described by the attributes that a geoscientist may use in the field to determine which slopes are more likely to generate landslides
Slides in Rock
Steep rock slopes and cliffs can fail under the influence of gravity, often triggered by intense rainfall or earthquakes, and generate slides in rock. Slides in rock are usually very fast, and the failure can occur along planar, curved, and/or multiple surfaces. By mapping the distribution of previous landslides, slope angle, rock types, and other terrain properties, it is possible to identify the slopes more susceptible to slides in rock.
Debris Flow
Intense and persistent rainfall infiltrates bedrock and surficial material, increasing pore water pressure, which sometimes results in slope failure. Debris flows are generated when such a landslide intersects a flowing body of water, or when saturated bed sediments are mobilized and begin flowing downstream. Debris flows can be very destructive, frequently damaging buildings and roads constructed on debris flow fans.
