Seawalls provide short-term protection against erosion but may have long-term negative impacts on coastal environments and properties.
Seawalls are structures built along coasts to protect properties from erosion and storm surges. Initially, they may seem effective in reducing erosion and protecting land from storms, but in the long run, they can lead to unintended consequences.
While seawalls can decrease the present risk of immediate erosion and damage to properties, they may increase the future risk by impacting coastal habitats, sediment flow, and wave behavior, ultimately posing challenges to the environment and infrastructure.
It's essential to consider the geological and ecological costs of seawalls and explore a balance between protection and preservation of natural coastal processes to ensure sustainable coastal management.
