How to prevent Coastal Erosion?
Preventing coastal erosion requires a combination of natural and engineered solutions. Here are some strategies commonly used to mitigate coastal erosion:
- Beach Nourishment: This involves adding sand or sediment to beaches to replenish eroded areas and restore natural coastal features. Beach nourishment can help absorb wave energy, reduce erosion, and maintain recreational and ecological values of beaches.
- Vegetation Planting: Planting native vegetation such as grasses, shrubs, and trees along the coastline can help stabilize soil, reduce wave impact, and promote sediment deposition. Coastal vegetation also provides habitat for wildlife and enhances biodiversity.
- Living Shorelines: Living shorelines are nature-based solutions that use natural materials such as plants, oyster reefs, and marsh vegetation to stabilize the shoreline and reduce erosion. Living shorelines can provide effective erosion control while enhancing habitat and water quality.
- Breakwaters and Groynes: These structures are built offshore or along the coast to dissipate wave energy and protect the shoreline from erosion. Breakwaters are submerged or partially submerged barriers that reduce wave height and intensity, while groynes are structures that extend perpendicular to the shore to trap sediment and prevent longshore drift.
- Seawalls and Revetments: Seawalls are hard structures built parallel to the shoreline to protect coastal properties from wave action and erosion. Revetments are sloping structures made of concrete, rock, or other materials that absorb wave energy and prevent erosion along the shoreline.

Coastal Erosion
Coastal Erosion is the wearing away of the land near the coastline. It removes sediments from beaches, dunes, cliffs, and coastal wetlands, mainly due to wind, waves, high tides, and storms. Coastal erosion is a natural process that shapes the world’s coastline but is also a significant environmental issue.
