Gabion walls are used to prevent erosion on shorelines, stream banks, and slopes. They are also used as retaining walls, temporary flood walls and silt filtration for some dams, lining channels and river training. Gabion walls are also often used on small streams as fish barriers and to direct the flow of flow water in a different direction.
Designs similar to gabions are used in many civil engineering projects such as dams. A person may use them to help with erosion control on their property. The main difference between what a gabion is used for is what it is made out of.
