Riprap

Definition

Riprap is a foundation or sustaining wall of stones placed together without order, often used in deep water or on an embankment to prevent erosion.

Purpose

The purpose of riprap is to protect soil from erosion by absorbing and deflecting the impact of waves, flowing water, or weather events, thereby stabilizing shorelines, riverbanks, and other areas prone to erosion.

Examples of Use

• Riprap is used along riverbanks to prevent erosion during high water flow.
• Coastal areas employ riprap to protect against wave action and prevent shoreline erosion.
• Highway embankments utilize riprap to stabilize slopes and prevent soil movement.

Related Terms

• Gabion: A cage or box filled with rocks, used for building erosion control structures.
• Armor Stone: Large, heavy stones used to protect structures from wave action.

Notes

Proper installation of riprap is crucial for its effectiveness, requiring careful placement and selection of appropriately sized stones to ensure stability and durability.
