Levees are structures that allow for the effective control and use of water resources. A leve is an artificial structure made of earth, rocks or other materials (mainly concrete) that is used to prevent flooding. It is usually built near or over rivers, streams, lakes or wetlands. In modern times, they have proven to be invaluable tools in combating flooding, soil erosion and agricultural damage. Flood protection levees help reduce the risk of flooding in the areas surrounding rivers. This is achieved by using the leve structure to prevent or reduce the amount of water that can move through the area. In agriculture, levees help retain water in meadows near crops. This makes it easier to irrigate plants and animals without having to carry water from far away. In addition, they can be used to prevent water from flooding fields and reduce erosion when placed on a slope. As climate change and rising sea levels continue to cause more frequent flooding, levees play a critical role in protecting vulnerable areas. Not only do levees protect against flooding, they can also help create and protect wetland areas – areas that provide essential habitats for waterfowl, fish and other aquatic life.
