Question

When people build houses and roads, they often pile up dirt or cut into the sides of hills. Predict how this might affect sediment on a slope. Explain how to control the effects of such activities.

Answer 1

The activities of building houses and roads can have a significant impact on sediment on a slope. When dirt is piled up or hills are cut into, it can cause erosion and destabilize the slope, leading to increased sediment runoff. To control the effects of such activities, it is important to use erosion control measures such as terracing, contour plowing, and the use of vegetation to stabilize the soil. Additionally, sediment basins and sediment traps can be used to capture and contain sediment runoff.
