What is riprap?

Riprap refers to a layer of large rocks or stones that is used primarily to protect shorelines, riverbanks, and other structures from erosion caused by water flow. The primary function of riprap is to absorb and deflect the energy of waves or flowing water, reducing the potential for soil erosion. When properly installed, riprap can stabilize the bank and prevent sediment from being washed away, making it an effective erosion control measure. This is especially important in areas where there is significant water movement, such as along rivers or lakes.

The materials used in riprap are typically larger and more durable because they need to withstand the forces of nature over time. This method is often preferred in engineering and environmental practices for its effectiveness and longevity in protecting sensitive areas from erosion and sedimentation.
