Coastal management

Key points:
Techniques for managing coastal erosion fall under two categories - hard engineering and soft engineering.
Hard engineering tends to be expensive. Solutions can be unsustainable and have a high impact on the landscape and environment.
Soft engineering options are often cheaper. They are usually more long-term and sustainable, with less impact on the environment.
Beach management is replacing eroded beach or cliff material. It requires constant maintenance to keep replacing the material as it is washed away.
Managed retreat is where low value bits of coast are allowed to erode and flood naturally.
