A basic levee is simply a long mound of earth piled along the banks of a river to contain the waters if they threaten to flood. The levee systems along the Mississippi, however, are engineered and built to high standards. Between the normal riverbed and the levee structure is an expanse of land, often a mile or more wide, called the batture.
