In civil engineering of shorelines, hard engineering is generally defined as controlled disruption of natural processes by using man-made structures. It is sometimes considered to be the use of concrete break walls  to limit the amount of coastal erosion on a being or a cliff-face where land is being absorbed by the sea or steel sheet piling to stabilize shorelines and achieve safety along the coastline to limit the amount of sand being transported by long shore drift

 Steel sheet piles

long structural sections with a vertical interlocking system that creates a continuous wall. The walls are most often used to retain either soil or water. The ability of a sheet pile section to perform is dependent upon its geometry and the soils it is driven into. The pile transfers pressure from the high side of the wall to the soil in front of the wall.

There are permanent and temporary applications. Permanent sheet piles remain in the ground and serve as permanent retaining structures. Temporary sheet piles are designed to provide safe access for construction, and are then removed.
