Session 5
: Preparation and prevention of floodingSlide2
Session 5 Objectives:
All pupils will recognise that there is a difference in preparedness for flooding between the UK and Pakistan.
Most
pupils
will be able to explain why there is such a difference in flooding preparedness and the impact this has on flood recovery.
Some
pupils will be able to explain how flood prevention works and how effective these measures are.Slide3
What do YOU think?
This picture shows a fight breaking out at one of the camps formed after the flooding. It started because the blankets ran out.The woman at the centre was interviewed after and said that when aid reached them ‘it was too little, too late’.Slide4
Flood prevention
Winnipeg was severely flooded in 1950.To protect the city from future floods, the government undertook the construction of a massive system of diversions, dikes, and floodways (including the Red River Floodway and the Portage Diversion).
The system kept Winnipeg safe during the 1997 flood which devastated many communities upriver from Winnipeg.
CASE ONE: Winnipeg, USA:Slide5
Flood prevention
In China, flood diversion areas are rural areas that are deliberately flooded in emergencies in order to protect cities.However this has led to a lot of deforestation.
CASE TWO: China:Slide6
Flood prevention
The Zuiderzee Works are a manmade system of dams, land reclamation and water drainage works, the largest hydraulic engineering project undertaken by the Netherlands during the twentieth century. The project involved the damming of the Zuiderzee, a large, shallow inlet of the North Sea, and the reclamation of land in the newly enclosed water using polders.
Its main purposes are to improve flood protection and create additional land for agriculture.
CASE THREE:

Flood prevention
The estuaries of the rivers Rhine, Meuse and Scheldt have been subject to flooding over the centuries. After building the Afsluitdijk, the Dutch started studying the damming of the Rhine-Meuse Delta. Plans were developed for shortening the coastline and turning the delta into a group of freshwater lakes. By shortening the coastline fewer dikes would have to be reinforced.
CASE FOUR: Afsluitdijk, Netherlands

TASK: Flood prevention
Using what you have learnt about flood defences, you now have to work as a TEAM to plan, design or build one of them.You can only use the materials provided and MUST produce a detailed plan of your work!You will have to FEEDBACK to the class about what you find out!Slide10
Money, money, money!
It revealed that only 356 of 630 schemes that had previously been in line for 2011/12 capital funding are set to receive money this year. This means many towns in Britain will be left unprotected.
