Slope Failure and Debris Slump on Oversteepened Roadcuts.

Illustration of an oversteepened roadcut and debris slump showing how stormwater diversion onto loose fill leads to slope failure and debris movement.

The diagram illustrates two side-by-side images of a roadcut where debris slumps occur due to oversteepened slopes and stormwater diversion. On the left side, the oversteepened roadcut shows excavated debris from slope instability. The right side depicts heavy rainfall exacerbating the slope failure, leading to a debris slump. Stormwater is diverted onto loose fill, increasing the pressure on the slope and causing it to fail along a marked failure plane, resulting in the downward movement of soil and debris.

This illustration is ideal for geology and earth science textbooks.
