Coastal protection case study- Ventor to Bonchurch on the Isle of Wight
Geology- mix of chalk, greensand, and clay leads to rotational slumping
which creates linear beaches separated by steep slopes, mudslides- clay
exposed making it vulnerable in rain, rock falls, landslides
Becomes unstable after heavy rain
Vulnerable to wave attack due to storm surge from Atlantic (south south
west waves create 1m higher than normal surge), narrow beaches (limited
sediment supply), abrasion from storms that throw gravel at cliff
High socio economic value due to coastal resort, residential area, millions
worth of residential/commercial property, main communications route
passes through
Continuous sea wall (hard engineering) used as it's the only viable option to
protect area from wave attack and sub aerial processes.
