Coast case studies

Question 1

$3 Billion of damage
Killed 6,400 people
Fastest storm on record (300km/h)
Made 1.9 million people homeless in the Philippines
Storm surge from it was similar to a tsunami
Destroyed 30,000 fishing boats
Damaged or destroyed 600,000 hectares of farmland
Affected over 16 million people
Lead to riots, food shortages and diseases

Question 2

High energy coastline - Green bridge of wales

Answer 2

What is it: An Arch Where? Wales

High energy coastline = destructive waves more erosion

Coastline is Composed of a very thick layer of Carboniferous Limestone,

Chemical erosion has dissolved the limestone.

Question 3

The Whitby shore platform - wave cut platform- factors involved in the creation of an erosional landform

Answer 3

Located in Yorkshire

Coastline is sandstone and discordant

Question 4

Old harry -caves, stacks and stumps- factors involved in the creation of an erosional landform

Answer 4

Located on the headland between Swanage and Studland Bay.

Made of chalk - sedimentary

Chalk is weathered by carbonic acid

Formation= soft rock eroded around hard rock - headland then cave, arch, stack and stump

Question 5

Ynylas spit

Answer 5

Prevailing winds blows at an angle to the coast causing longshore drift which deposits sediment to build up a spit

Question 6

Nile Delta - Human activity on coast - farming

Answer 6

Location: North Egypt

Estuary is useful for farming cause land is fertile however, the silt is easily saturated and due to being built on estuary can easily flood

Question 7

Weymouth bay - Conservation of coasts

Answer 7

South Coast of England in Dorset

Protected by UNESCO as a heritage site due to varied geology or unique landforms

Jurassic Coast

Question 8

The North Sea Coast - Low Energy Coastline

Answer 8

Location: Netherlands

Constructive waves more deposition, gentle slopes and sand dunes

Question 9

Yucatan Peinsula - Human Activity

Answer 9

Location - Mexico
8% of Mexico's GDP is tourism
Thousands of jobs generated
Second most visited place in the world
Multiplier effect
One of the seven wonders of the world
Second biggest barrier reef located here

Question 10

Lywyth cove

Answer 10

Concordant coastline

Question 11

Swanage bay

Answer 11

Discordant coastline

Question 12

Holderness

Answer 12

Located: North East England
11km of sea wall
Eroding inland 1.8m per year
Hold the line

Question 13

Torquay - management strategies

Answer 13

Pinning - putting large pins into cliff faces to prevent sub aerial erosion

Question 14

Blackwater estuary

Answer 14

Salt marsh - high salinity - used as natural defence from coastal erosion because it reduces induces wave refaction

Question 15

Great Barrier Reef - World heritage site

Answer 15

World Heritage site
Natural defence - The coral reef structure buffers shorelines against waves, storms, and floods
High vulnerability due to global warming as zooxanthellae dies from increased temperatures causing the coral to bleach which makes it less effective

Question 16

Walton-on-the-naze - management

Answer 16

Location: North East Essex Coast

They’re cliff profiling (Making cliffs be at angles to make them less susceptible to erosion
