The Maldives are a collection of Islands in the Indian Ocean. The Maldives are about 400 Miles southwest of India.
Studland Bay is located in the Isle of Purbeck in Dorset
Fact
Depositional feature- spit
The village of Mappleton, perched on a cliff top on the Holderness coast, has approximately 50 properties. Due to the erosion of the cliffs, the village is under threat.
Hard engineering
A rotational landslide involving about 1 million tonnes of glacial till cut back the 60 m high cliff by 70 m.
Soft engineering
The Maldives has the lowest average height above sea level of any country (1.5 m or 4.5 ft.)
The nature reserve is an area of sand dunes. These are dynamic, but often unstable and vulnerable environments.
Point 1
A spit is formed- prevailing wind hits the coast at the oblique angle.
A coastal management scheme costing £2 million was introduced involving two types of hard engineering - placing rock armour along the base of the cliff and building two rock groynes.
Hornsea is a seaside town on the Holderness coast
It flowed across the beach to form a semi-circular promontory 200 m wide projecting 135 m outward from the foot of the cliff.
Let’s a certain area e.g. Field to flood.
The population of the Maldives is 328,536 people.
Tourists bring their problems such as litter and fire hazards (caused by barbecues and cigarette ends).
Point 2
The swash carries material up the beach in the same direction as the waves.
Mappleton and the cliffs are no longer at great risk from erosion
Hornsea, rock armour, rock groynes, sea walls rainfall of 140 mm in the two months before the slide took place
Because of the low elevation, the Maldives will be completely under water if sea level
