In this lecture, we were shown the power of natural disasters and how devestating they could be. This first one that we covered was hurricane Katrina that completely destroyed New Orleans. We also discuss why that system that was put in place failed, and the political things that could have come from the areas damaged. We were shown that the leeves's and I-walls failed because of the design of them. They were not up to date and once they tipped over, they were easily about to be knocked over. They also, because of the time that the structure was made, had a factor of safety that was less than the stardard now. This lecture focused on the damage that hurricanes can pose when certain protections are not up to standards. Because of these leeve's not being to the standard, and original design, the damage cause could have been heavily mitigared. Aside from damage due to a hurricane running through the area, poor planning lead to most of New Orleans being flooded and destoryed.
