Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
This image represents a typical seawall that is used for preventing and controlling coastal erosion. Hard-erosion control methods provide a more permanent solution than soft-erosion control methods. Seawalls and groynes serve as semi-permanent infrastructure. These structures are not immune from normal wear-and-tear and will have to be ...

Gully erosion may also advance laterally through similar methods, including mass movement, acting on the gully walls (banks), and the development of 'branches' (a type of tributary). Gullies reduce the productivity of farmlands where they incise into the land and produce sediment that may choke downstream waterbodies and reduce water quality ...
The most effective known method for erosion prevention is to increase vegetative cover on the land, which helps prevent both wind and water erosion. [114] Terracing is an extremely effective means of erosion control, which has been practiced for thousands of years by people all over the world. [115]
A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...
Examples of Erosional Landforms; Landform Description Image Deflation basin: A depression in the land that can be found in deserts due to the removal of particles by wind; it can also be referred to as a "blowout". Blowout outside of Earth, Texas: Ventifacts: Rock samples that demonstrate the erosion caused by aeolian processes over time.
