marginal dikes

Dams are structures that allow the control and effective use of water resources. A levee 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 on 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 areas surrounding rivers. This is achieved by using the structure of the dam to prevent or reduce the amount of water that can move through the area. In agriculture, dams help retain water in meadows near crops. This makes it easier to water plants and animals without having to carry water from afar. Additionally, 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 key role in protecting vulnerable areas. These not only protect against flooding, but can also help create and protect wetland areas, areas that provide essential habitats for waterbirds, fish and other aquatic life.
