In much of the world flooding is a serious issue. The water and erosion caused by flooding does damage to crops, private, and public property. GIS can be used to identify and map out problems caused by flooding, it can also be used to analyze these problems, make predictions, and come up with solutions in order to try and reduce the damage caused by these floods. The purpose of this study was to use GIS in order to do just that, predict flooding and erosion, in hopes of keeping people safe and minimizing damage. They used physics equations to measure the speed and force with which the erosion occurred, they used these equations and numbers to map out the erosion. Not only was the erosion mapped but they also mapped the areas that were most dangerous. In this study they were able to map out areas that would be most likely to be destroyed by flooding. Information like this is incredibly valuable in improving the quality of life and protecting the people who live in areas that are so heavily impacted by floods.

  1. Within the last few years in the DFW area there have been some major floods. Floods can hurt the whole community even if you weren't personally affected. As technology progresses I have been able to seen several news stations publishing GIS information for the communities so they are aware of what could potentially happen.

  2. It would be interesting to find out how the flooding effects the moving of a population. does the general population move out and return for a later date or do major floods completely change the build up of a town.

  3. Since it shows the predicting flooding and erosion areas, it is going to be really useful local residents to move out to some safer area and avoid those dangerous areas. Using GIS in this case pretend local resident in some way.

  4. Like Landon, I wonder about the shifting of populations after floods. Once restored, does the real estate that was restored typically decline? Who moves back into these areas? What is the return rate for those who were already living there. You could use GIS to find this out and compare the maps to one another.
