What is the function of a levee?
Levees are usually built to hold water. They should be constructed with a slope allowing erosion free maintenance. The slope will vary with different soil types. Some levees tops are wide enough to drive vehicles on for inspection and maintenance. Levees are used to hold back flooding from waterways during heavy rains, are the most cost effective method of lake construction. Levees distribute water over vast distances to crops and cities hundreds of miles away where they are often lined with concrete. Levees are a big part of our lives even though we seldom notice them.
