Mississippi Leeves Could Fail

The earthen leeves in Mississippi can't hold up any longer, some peoples houses, farms etc. will be 25 feet underwater retreats. The leeves should keep the bigger towns and cities safe, but the immense force of the water can easily do away with the leeves. After all, leeves are just pile of dirt, so the leeve can be effortlessy eroded untill a once small hole becomes larger allowing the water to pass through. Another posibility is a sand boil or mud boil, which is when the waters force pressures against the bottom of the leeve and get to the dry side. Lastly, too many days of flooding can drench the leeves soil causing a washout. Either of these are likely, and if one of these do show itself, immediate action will be taken to save the places and people around this amazing river.
