- Sandbanks
- Peninsula - land almost surrounded by water on all sides
- Sandbanks peninsula separates much of poole harbour from poole bay
- Two bays shoreline management plan
- produced by local councils and environment agency to take most sustainable approach to coastal management
- designed by poole harbour commission, poole borough and the environment agency
- based on movement of sediment within sediment cell covering poole bay and christchurch bay
- Two bays shoreline management plan
- Sandbanks peninsula separates much of poole harbour from poole bay
- Uses of the peninsula
- Economic
- Sanbanks hotel and haven hotel which provide employment opportunities and generate spending
- residential properties are in high demand with premium prices
- large detached houses over £10m and many apartments over £2m
- Tourism
- blue flag beach award - water quality and the gentle slope which makes it safe fro family swimming
- provides protection from waves in poole harbour so makes it safe for sailing and wind surfing
- Geography
- longshore drift has caused the harbour entrance to become clogged an shallow
- the harbour is used for cross channel ferries and commercial ships carrying timber
- climate change predicts the sea level to rise 0.6m in the next 100 years
- junction of shore road and banks road is only 2m above sea level
- if management doesn't occur it is estimated £18 million damage will be caused in next 20 years
- junction of shore road and banks road is only 2m above sea level
- longshore drift has caused the harbour entrance to become clogged an shallow
- Economic
- management
- hard engineering
- rock groynes- constructed to minimise longshore drift to maintain a deep and wide beach
- to ensure sediment stops entering harbour entrance so it can remain free for shipping
- the rocks also absorb wave energy, reducing rates of erosion
- rock groynes- constructed to minimise longshore drift to maintain a deep and wide beach
- soft engineering
- beach recharge is used to conserve beaches
- sand is dredged from offshore and sprayed onto the beach through 'rainbowing'
- it add to the size of the beach and costs £20/m3
- sand is dredged from offshore and sprayed onto the beach through 'rainbowing'
- new experiment in last few years has been very successful and only costs £3/m3
- sediment is dredged from poole harbour and s dumped just offshore letting natural maintenance of the beach happen
- beach recharge is used to conserve beaches
- hard engineering
- Peninsula - land almost surrounded by water on all sides
