15.2 Classification of Mass Wasting Physical Geology

If the material involved is primarily sand-sized or smaller, it is known as a mudflow, such as the one shown in Figure 15.16. Figure 15.16 A slump (left) and an associated mudflow (centre) at the same location as Figure 15.15, near Lethbridge, Alberta. [SE] If the material involved is gravel sized or larger, it is known as a debris flow.

15.2 Classification of Mass Wasting Physical Geology

15.2 Classification of Mass Wasting There are three criteria used to classify slope failures: The type of material that failed (e.g., bedrock or unconsolidated sediment), The mechanism of the failure (how the material moved as it failed), and; The rate of movement (how quickly the material moved).

Landslides, Slope Failure, & other Mass Wasting

Construction of homes on unstable slopes has similar effects. Changing the slope face, the additional weight (homes and fill material), plus the added water (homeowners' sprinkler systems and septic tanks) make a formerly stable slope unstable. Add a heavy rainy season and

10 Mass Wasting An Introduction to Geology

10.2 Mass-Wasting Triggers & Mitigation. Mass-wasting events often have a trigger: something changes that causes a landslide to occur at a specific time. It could be rapid snowmelt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, rapid-stream erosion, or human activities, such as grading a new road. Increased water content within the slope is the most common mass-wasting

Dry sand cannot hold a form, so the addition of water is necessary to build the castle. However, too much water will destroy the sandcastle and cause the sand to flow away in a slurry. This is similar to the role pore water has on sediments in a slope.
