Coasts: Hard Engineering

The video discusses natural coastal processes like erosion and flooding, which pose challenges for coastal communities. It explains two main strategies for managing these processes: hard engineering and soft engineering. Hard engineering includes methods like sea walls and rock armour, which are costly and less sustainable. Soft engineering offers more sustainable and cost-effective alternatives for coastal protection.

Explain the potential drawbacks of using hard engineering solutions like groins and revetments.

What are some advantages of soft engineering techniques compared to hard engineering solutions?
