An earth wall designed to control water levels.
The correct answer is: an earth wall designed to control water levels.
A levee is a type of flood control system that consists of an earth wall or embankment. It is designed to prevent or control the flow of water, typically along rivers or coastlines, thereby reducing the risk of flooding and water damage to nearby areas. Levees are constructed using various materials, such as compacted soil, sand, concrete, or even steel, and they are typically built in areas that are prone to flooding or near bodies of water. The purpose of a levee is to hold back the water and redirect it away from populated areas, mitigating the potential impacts of flooding during events like hurricanes.
