Starter: Mind-map all the different things people use coast lines for. What are Coasts used for?
Some coastlines are under threat of erosion causing cliffs to retreat and beach material to be lost. Others are at risk from coastal flooding . In many cases the decision has been made to try and reduce the erosion to protect the coastline. This is called COASTAL MANAGEMENT. Coastal Management = The attempt by people to maintain the natural features of the coast for their own advantage
Types of Coastal Management HARD ENGINEERING Hard engineering options tend to be expensive and short-term options. They may also have a high impact on the landscape or environment. SOFT ENGINEERING Soft engineering options are often less expensive than hard engineering options. They are usually also more long-term and sustainable , with less impact on the environment.
The best example is the nourishment of beaches at Miami Beach where 17.7 million m³ of sediment was dredged & moved to the beach to provide an area for recreation & also to protect the expensive properties that were found in the location.
The problem with beach nourishment is that one severe storm event may remove vast amounts of the expensive sediment.
