How do both jetties and seawalls help manage beach erosion?
Jetties and seawalls are both structures designed to help manage beach erosion.
Jetties are long, narrow structures that are built perpendicular to the shore. They are typically made of rocks, concrete, or other durable materials. Jetties help manage beach erosion by trapping sediment that would otherwise be washed away by the currents and waves. This trapped sediment helps build up the beach and protect it from further erosion.
Seawalls, on the other hand, are vertical structures built parallel to the shore. They are typically made of concrete or other solid materials and are designed to absorb the energy of incoming waves. Seawalls help manage beach erosion by reducing the impact of waves on the shoreline, which helps protect the beach from erosion.
Both jetties and seawalls can be effective tools for managing beach erosion, but it is important to consider their potential impacts on the surrounding environment and ecosystems. Properly designed and maintained structures can help protect beaches and coastlines from erosion, but poorly constructed or poorly maintained structures can have negative impacts on coastal ecosystems and wildlife.
