Sandpipes refers to a sand-filled inclined structure that is commonly used to control the flow of sediment, such as sand, in order to prevent erosion in coastal areas. This term originated from the combined words "sand" and "pipes" which accurately describes its function and structure.
Typically, sandpipes consist of a series of parallel pipes that are partially buried in the ground, inclined towards the direction of sediment transport, and filled with sand. These structures are strategically placed to create a barrier against the movement of sand, preventing it from being carried away by water currents. The sand-filled pipes act as filters, allowing water to pass through while the sand particles settle, minimizing erosion in the surrounding coastal areas.
By controlling the sediment transport, sandpipes help to stabilize the shoreline, protect coastal infrastructure and habitats, and restore natural processes in areas affected by erosion. They are commonly used in beach nourishment projects, coastal restoration initiatives, and erosion control measures.
Sandpipes are often designed to be flexible, allowing them to adapt to changing sediment patterns and water flow conditions. The size, number, and orientation of the pipes can vary depending on the specific project requirements and the scale of erosion being addressed.
Overall, sandpipes are an effective engineering solution that utilizes the properties of sand and hydraulic processes to manage sediment movement and prevent coastal erosion.
