For Flood Control: Different Types of Levees

With changing climate patterns, more places worldwide are now battling floods. Floods are among the most destructive natural catastrophes your area might have to deal with. Thankfully, there is now a solution for flood control in civil engineering.

There are various engineering options you have for your area’s flood control management from a New Orleans firm. One of these is a levee. This is a mound or artificial material or earth built along your water bodies to prevent overflowing. Here are the primary types of levees that might benefit your area.

Embankment Levee

This is the most prevalent levee option. An embankment levee is typically made from compacted earth fill from excavations in your locality. Its foundation is stripped to remove organic matter and topsoil. Embankment levees are the ideal choice in places where there is enough space to accommodate satisfactory batter slopes.

Sheet Pile Levee

This option comprises one wall made of driven sheet piles. The piles’ size is determined by your levee’s height, required embedment height, and expected durability of the levee. Sheet pile levees are a perfect solution in places with limited space or where a water body’s banks are excessively steep.

Ring Levee

This encircles the areas of your water body that are prone to flooding. The levee is high, sturdy, and constructed in distinct areas. A spillway typically surrounds ring levees for extra flood control, as it allows slow release of water into your protected territory. This minimizes the risk of your levee breaking down from excess water.

Civil engineers might recommend various reinforcements for the above levees including aprons and T and I-walls. These prevent water erosion in your levee and minimize its risk of disintegration. Some areas have been known to suffer flooding even with the existence of levee systems. This is because the above systems should be continuously updated to handle the current flood risks failure to which they might be inefficient.
