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.
