Flooding in an LEDC: Can be used for an impact of a flood or used for the human and physical
causes of a flood
Location: Pakistan, areas of Punjab, Sindh and Swat Valley. July 2010
River: Indus river
Causes of the flood:
Heavy rainfall, 200mm in 24hours left soil completely saturated, no more infiltration, left with water
A pattern of monsoons leading to mass surface run off and further saturation of soil/ground
Ilegal deforestation. Only 5.2% of Pakistan is forest, and 70% of this was deforested by the
Timber Mafia
Some believe that climate change has exacerbated the heavy rainfall
Effects: (S=social E=economic EN=environmental)
S 2000 people dead
S 4 million homeless
E total economic damage is about 10% of Pakistans GDP
E Cost to provide tempary accomodation for the homesless, setting up camps etc
S and E Risk of water born diseases is huge, with a lack of drinking water that is clean, possible
cholera and typhoid breakouts
S and E With broken means of transport (trains roads etc) it was hard for supplies to be given to
people, they resorted to dropping supplies from a helicopter
S and E and ENV Dams are destroyed which one is a big loss economically, two will cause excess
water and more flooding and three cannot be infiltrated and all that stuff
E Only a small amount of $45,000,000 spent, which is not enough
S power plants destroyed, many left without electricity
S and E many people affected were in poverty, they are unable to afford to rebuild there houses...
S and E 30% of cotton crops destroyed as well as rice crops, lead to inc in price of rice and
cotton and lead to unemployment for many
S subsistence farming was ruined and this way the way of life for many
Flooding in an MEDC: Can be used for an impact of a flood or used for the human and physical
causes of a flood
Location: Gloucestershire, areas affected are Gloucestershire, Tewksbury, Cotwolds. 2007 July
River: River Severn
Many properties in Gloucestershire were build on the river Severns flood plain, reduced infiltration
due to concrete structures, increased risk of impact of a flood event
Farmers would farm on peat bog. Peat bog is a natural 'sponge' and farming here meant reduced
infiltration and interception and increased surface run off
Heavy rainfall, 2 months worth of rain in half a day

Here's a taster:

S 5000 homes and businesses destroyed
S 50,000 homes without electricity for two days
E £25,000,000 of damage
S and E Thousands needed tempory accomodation
S Commuters were stranded on roads over night
E 1500 bowsers were deployed ( big water containers)
S and E and EN Tewskbury sewage plant was flooded, leading to risk of disease
An area using soft engineering:
Location: South East London, Greenwich and Lewisham
River: River Quaggy

Here's a taster:

Advantages (A) and Disadvantages (D):
A, reduced major flooding from every ten years to every 100 years
A, with hydroelectric power, it is a sustainable and cheap way to generate power, enough to
supply 3% chinas demand
A, reservoir is now used more for shipping as its so deep
D, people have had to be relocated as water level in the reservoir rises, 2 million people.…read more

An area using Soft engineering:
Location: Black Water estuary, Essex Coastline
Isostatic (crustal sinking aka the land is sinking due to tectonic shit) sea level change is causing the
southern coastline to sink. Erosion rate up to 10m/year in places.
What's been done?
Coastal realignment in the form of a sea wall being breeched in Tollesbury Fleet creating and
marshland. A new LOWER sea wall was created.…read more

Here's a taster:

E house prices decrease, even million pounds properties
E insurance is up
At Bridlington the number of visitors has decreased by 30% putting economic strain
remember to elaborate all the points or you are fucked
An area of coastal flooding:
Location: Norfolk england, Netherlands
Low pressure across Denmark and High pressure along Ireland caused strong winds
The gale force winds created violence at sea
Large open water created a large area for waves to accumulate, a large fetch
High tide of North Sea
Effects:…read more
