The Mississippi River levees are protected from erosion by riprap, large chunks of concrete.

The outer part of the berms are made of earth, but I believe that in some places the bases are built up with timber, stone and gravel, maybe sand bags. Levee construction began a couple hundred years ago, piece meal, until the 20th century.

There is a long flat area of land between the river and the levee which is called a "batture" or a "scarp", which is usually more or less dry. Acts as a floodplain.

One former family plantation and cotton warehouse is now a batture, and leased out as a cow pasture. Pretty place if you don't mind mosquitoes.

Edit: it may be that these days the Mississippi River levees are constructed primarily from compacted impervious clay soil.
