1.2m deep foundations for Marina costed £2.2mil alone.
Brighton Marina covers 127 acres
only has 0.3m erosion annually
hold the line
Newhaven
Breakwater was built in 1791 and they have been beach recycling
since 1936
hold the line
50 groynes built due to tourism in 1900
in 1987, a massive beach replenishment of 3 million tonnes of
Seaford shingle was dredged from sea banks off the Isle of Wight
has a population of 27,000 ppl now
each year 50,000 tonnes tonnes of shingle is recycled a put at the
western end of the beach
no active intervention
erodes 30-35cm annually
Birling Gap
almost 7000 homes in england and wales are expected to fall into
the sea in the coming decades
3mm rise annually
rising sea levels approximately 2mm is due to thermal expansion
1mm due to melting glaciers
natural and man made defences here currently protect 10,000
properties
the project to protect this stretch of coastline begun in 2000 and
had an initial budget of £30 million
lorries transport 5000m^3 of sediment annually
Pevensey Bay, East Sussex
20,000m^3 of sediment is dredged from the sea flood to replace
the lost sediment. it is also placed on the beach
groynes here are left and if they break the wood is used to
strengthen the other groynes. instead of restoring 150 groynes
(which would have costed £12mil)
mangroves can grow up to 25m
Mangroves cover 0.1% of the earths surface
capture and store x5 more carbon than terrestrial rainforests
80% of the country is low lying
30% live in coastal zone
The Sundarbans, Bangladesh
around 145 million people located closed to the river
80% of bangladesh lies on a floodplain.
the World Banks multipurpose disaster shelter project (MDSP)
the sundarbans - examples of resilience
have constructed over 550km of evacuation roads since 2015
the sundarbans - mitigation
