Essay 1 Title…………………………………………………………………………

Certain human activities can have a great impact on river flooding which can also be linked to physical causes of flooding

The Philippines has a GDP per capita of just $2700, making it an LEDC. As a result of this, they had little funds to prepare and plan for the flooding in 2009 cuased by Typhoon Ondoy. Flooding in the capital city of the Philippines, Manila in 2009 caused infrastructural damage of 570,187,587 Philippine pesos, approximately £8.5 million. Whilst this number seems high, it is important to remember that this is a world city, made up of 12 million inhabitants, therefore the damage equates to less than £1 per person. By way of contrast, a storm event in rural England (which has a GDP per capita of $39,000) in Cumbria had a cost of £275 million. These facts taken alone indicate that the economic impact of flooding ins far worse in MEDCs.

Drainage systems also don’t help as a human cause. Water is carried straight to the river via drains instead of gradually getting there via groundwater flow. An example of this was found in Keswick in November 2009, where a heavy rains caused flooding with river discharge of 265 cumecs. It took just 3 hours from the storm event for the River Greta to overflow into the hospital field, posing a threat to health. Also human causes include deforestation , often attributed to urbanisation,– by cutting down trees, vegetation storage and interception is prevented meaning water reaches the river more quickly. This human cause can be linked to a physical cause. If a river channel is near to an area of naturally sparse vegetation the same effect occurs.

In Keswick, the flooding also affected homes and the environment. This was of particular importance as it is situated in the National Park of the Lake District and therefore relies heavily on tourism for income. 500 people were made homeless in total, far less than the figure in the Philippines. Due to more income, the majority of people were insured and therefore, despite the fact that the damage caused disruption, for the vast majority, it didn’t leave them in poverty. The only death in the Cumbria floods was that of a policeman who was trying to aid the evacuation of others from Cockermouth when the bridge he was standing on collapsed.

Overall the importance varies in that human causes can be minimised or prevented so physical causes seem to be the main problem.

Essay 2 Title…………………………………………………………………………

LEDCs suffer in a different way from flooding than MEDCs. Often the damage is less of an economic cost, but more socio-environmental.

In built up urbanised areas there are often rivers close by. The build up of impermeable surfaces like concrete pavements means that when precipitation occurs infiltration is not possible and rain water flows straight to the river channel as surface runoff, increasing lag time and river discharge – effectively causing a river to flood.

With regards to the social effects of flooding, in Manila, a large % of the houses are slums. This meant that they were more susceptible to damage from the flood event. In total, around 12,000 homes were completely destroyed. This figure doesn’t take into consideration the damage caused by the flooding to other houses, including where rain/river water was contaminated by sewage. The floods also killed 241 people. Considering the fact that the Philippines is affected by typhoons every year, this indicates a lack of planning and preparation which could be attributed to low economic development and therefore a lack of funding.

In Keswick, the flooding also had a social impact, however this appeared to have been more managed. The flooding affected homes and the environment which was of particular importance as it is situated in the National Park of the Lake District and therefore relies heavily on tourism for income. 500 people were made homeless in total, far less than the figure in the Philippines.

The only death in the Cumbria floods was that of a policeman who was trying to aid the evacuation of others from Cockermouth when the bridge he was standing on collapsed.

In conclusion, it does indeed appear that MEDCs suffer more in terms of economic cost of flooding, where LEDCs will instead suffer from a higher death toll

The Philippines and the UK are vastly different countries in terms of economic development, therefore it is understandable that the economic and social effects differ.

Flooding in the capital city of the Philippines, Manila in 2009 caused infrastructural damage of 570,187,587 Philippine pesos, approximately £8.5 million. Whilst this number seems high, it is important to remember that this is a world city, made up of 12 million inhabitants, therefore the damage equates to less than £1 per person.

Considering the fact that the Philippines is affected by typhoons every year, this indicates a lack of planning and preparation which could be attributed to low economic development and therefore a lack of funding.

Landscape is also a major physical cause. Low lying flat lands like the islands in the Philippines, created by volcanoes for example, suffer badly from lack of drainage. Being towards the end of the stream order hierarchy also added to the flooding in Manila in 2009.Typhoon season is also a major flood cause here as in typhoon season much rain falls on these unsuitable drainage basins. The flooding in Luzon in September 2009 affected 872,097 people in metro Manila, a highly urbanised mega city. This flood was caused by heavy rains during Typhoon Ondoy.

To conclude, it would appear that in LEDC countries, the damage caused by flooding is more of a social problem, whereas in MEDCs, where infrastructure and housing is more expensive, the majority of the effects are economic.
