What is a Levee?

Levee ConstructionThe National Flood Insurance Program (NFIP) defines a levee as “a man-made structure, usually an earthen embankment, designed and constructed in accordance with sound engineering practices to contain, control, or divert the flow of water so as to reduce risk from temporary flooding.” So, what is a levee in general terms…A levee is simply a man-made embankment built to keep a river from overflowing its banks or to prevent ocean waves from washing into undesired areas. Levees are designed to prevent flooding and to allow cities like New Orleans to have some protection against hurricanes.

What is a levee made of?

A levee is typically made from a mound of less permeable soil, like clay, wider at the base and narrower at the top. In addition, a levee can be built from sand, rocks or soil if the current is not expected to be rough. A levee for a stronger moving body of water is built from plastic, blocks of wood or metal. Concrete is used if the danger of flooding is higher than in other areas.For example, levees along the Mississippi River may range from 10 to 20 feet (3 to 7 meters) tall. In Holland, they can top 30 feet (10 meters). The height of the levees vary according to the storms the area receives. Sometimes, Floodwalls are used in conjunction with levees. Floodwalls are constructed on a levee crown to increase the height of a levee and are typically made of concrete or steel.

What are some of the best machines used for constructed a levee?

Levees are constructed through a variety of different types of environments but many of them involve soft terrains. Cranes and excavators are used to construct levees, but amphibious cranes and amphibious excavators are needed to construct levees through marshes and wetlands. What is an Amphibious crane or excavator? Amphibious Equipment, like an amphibious crane and amphibious excavator, is designed to work in wet, soft terrains with a unique pontoon construction with corrosion resistance, track chains, track shoes, and hydrostatic drive. This means that the equipment will float on top of the water while working to build the levee.
