Land reclamation on a beach may be necessary for various reasons, including to combat erosion, create new land for development, or protect coastal areas from flooding. An example of when land reclamation may be needed on a beach is when the shoreline is eroding at a rapid pace, threatening the homes and infrastructure built along the coast.
In such a scenario, the beach can be reinforced with various methods such as building a seawall, planting vegetation, or placing large rocks along the shoreline. However, if the erosion continues to worsen, more drastic measures such as land reclamation may be necessary.
Land reclamation involves adding sand, sediment, or other materials to the beach to widen the shore and create a buffer zone between the water and infrastructure. This can involve pumping sand from offshore or trucking in sand from other locations. By creating a wider beach, the force of waves and storms can be absorbed, reducing the impact of erosion on the shoreline.
Overall, land reclamation on a beach is a technique used to protect coastal areas and their infrastructure from the damaging effects of erosion and rising sea levels.
