What is riprap primarily used for?

1. Foundation support

2. Aesthetic landscaping

3. Erosion control

4. Road construction

The correct answer is: Erosion control

Riprap is primarily used for erosion control, which is crucial in managing the impact of water movement in various environments. This material, composed of large stones or boulders, is strategically placed along shorelines, riverbanks, and slopes to absorb the energy of flowing water, preventing soil erosion and protecting underlying structures from washout. By creating a barrier against the force of waves, currents, or runoff, riprap helps maintain the integrity of the landscape and prevents significant land loss over time. The use of riprap is particularly important near bodies of water where erosion can be a significant concern, such as in coastal areas or near rivers that experience high levels of flow. Its effectiveness in minimizing soil displacement and protecting habitats makes it a key component in environmental management and infrastructure protection.
