Shoreline management plan for this stretch of Coastline is to 'Hold the line' using hard and soft engineering- needed becasue soft rock which erodes at 1-2m per year without protection. Long fetch of 3000miles across atlantic btong powerful destructive waves that erode the coastline through the processes of hydraulic action and abrasion. Valuable land to be protected.
Stratagies used:
- 100 wooden groynes costing £100,000 each, creating 7miles of golden beaches
- 'Long Groyne' large rock groyne at Eastern end of Poole Bay
- Rock armour groynes at Westerns end of Poole Bay at Sandbanks.
- 5 new rock groynes at Branksome Beach, Poole 2008-2009, each measuring between 545m-75m in length. invloved 20,000 tonnes of rock being delivered to beach.Took 5 months and cost £1.9 billion
- Beach Nourishment- Between 2005-2008 the coastline benfited from 1.8 million cubic metres of beach material. Bournemouth beach 2008-2010 top up was from Isle of Wight. Water of Poole Bay is so shallow the dredger needed to pump the sand ashore through a long pip that lay on the seabed. Beach levelled by bulldozers
