1. What is hard and soft engineering?
2. Stick in the sheet with the information on add a positive and a negative
3. Use page 67 and 68 to add in the hard and soft engineering for Swanage
4. Annotate on your photo on the back where the different techniques are.
5. Complete the 6 mark question,

Beach Replenishment
Sometimes it is necessary to replace the sand and shingle that has been lost by the action of the sea. Lorries are used to transport material dredged up from the sea bed to the beach.
+ -
Rip Rap
These big boulders are usually placed at the bottom of a cliff. As the waves hit the boulders, their energy is lost so their erosive power is reduced. They are expensive.
+ -
Revetments
These are wooden posts with slats of concrete laid on top of the beach to stop the sand being eroded.
They are cheaper than sea walls, but do not last long where the waves have lots of energy.
+ -
Gabions
Metal cages filled with rocks. They are stacked together to make a wall to protect the coast.
They are much cheaper than other sea defenses but don’t last as long.
+ -
Curved Sea Wall
A wall with a rounded lip at the top. This breaks up the waves energy and reflects the waves back into the sea, stopping them going over the top. Expensive but last for a long time.
+ -
Groynes
Natural beaches are the best sea defence, but often they are washed away by longshore drift.
Groynes are cheap fences made from large wooden posts. They trap the sand and stop the beach being washed away. (look at the beach height either side of the groyne!)
