Vulnerability.

  • Climate.
  • Warm water from the gulf of mexico has lots of energy.
  • New Orleans is below sea level. prone to flooding.
  • High, dense population due to urbanisation.
  • Levees were not big or strong enough to hold the strom surge.
  • Oil drilling caused the land to sink. 
  • Human interference with the land, caused the land to sink further. For example, engineers drained wet lands to allow for more housing for the increasing pouplation. These wet lands would have been able to lower the impact of the storm surge, if they were not drained.

Response.

  • Slow response. President Bush was accused to responding too slowly.
  • Aid was refused at first, leaving people without food and water, dying on the streets. 
  • When aid was accepted, if was difficult to get through due to poor infrastructure and collapsed bridges. 
  • Aid was offered from around the world
  • The UK offered 350,000 army meals, but were rejected because of laws on mad cow disease. 
  • Evacuation to the Superdome. So tightly compacted there was higher risks of diseases spreading. 
  • Rescue teams abandoned duties to stop looting and violence. Troops were sent to Louisiana and Mississippi to maintain law and order.

Repair

  • Helicopters dropped huge sandbags.on the street canal to allow trucks to get across and bring in stone to strengthen repairs. 
  • Temporary barrier has been built on the canal to seal it off from Lake Pontchatrain. 
  • Pumping out flood water to drain the land. Could take 80 days.
