Hard and Soft Coastal Engineering

Starter

Coastal engineering is a type of management where strategies are put in place to protect areas from the effect of coastal erosion, transportation and deposition. Coastal engineering strategies can be categorized as being either 'hard' or 'soft'. Have a look at the following images - what coastal engineering strategies can you spot? [Hint: There are at least four in the image!]

Coastal Engineering Case Study: Mappleton, United Kingdom

Mappleton is a village on the Holderness coast, north-east United Kingdom. In 1991, coastal engineering strategies were put in place to protect the village from coastal erosion. The Holderness coastline is one of the most rapidly eroding areas of the UK. The cliffs had been eroded at a rate of 3.2 yards (2.9 m) per year. The building of the coastal engineering strategies caused controversy due to the slowing of the rate of erosion to the north of the groyne and the possible speeding up of the rate of erosion to the south.

Click on the placemarks on the map below to get a feel of the situation - thinking about how different people in the Mappleton community may feel about the building of the coastal engineering strategies.
