Natural levees are built up over time from debris and sediment whereas artificial levees are man made using sand bags and larger rocks.
A levee is an embankment along a stream that protects land from flooding. Levees can be natural or constructed. A dike is much the same, a protective wall, often to hold back the sea.
A traditional flood control method used to keep a stream's flow in its channel is the construction of artificial levees. These raised embankments are built alongside rivers or streams to prevent overflow during heavy rainfall or flooding. By confining the water within the levees, they help direct the flow and protect surrounding areas from flood damage. Other methods, such as dams, can also regulate water flow, but levees specifically aim to contain riverbanks.
People typically use a combination of materials to build artificial levees, including earth, clay, sand, and gravel. These materials are chosen for their ability to effectively block and redirect water flow. In some cases, levees may also incorporate geotextiles or other engineered materials to enhance stability and reduce erosion. The design and construction methods vary based on the specific environmental conditions and the intended purpose of the levee.
Dams are in front of the flow, levees are at the sides.
Levees were crucial to the Sumerians as they helped manage the flooding of the Tigris and Euphrates rivers, which could be both destructive and beneficial. By controlling floodwaters, levees protected agricultural land, ensuring stable crop production and supporting the growth of Sumerian city-states. This flood management system also facilitated irrigation, enhancing agricultural efficiency and contributing to the development of their economy and society. Overall, levees played a vital role in sustaining Sumerian civilization.
levees are artificial or natural slopes or walls to prevent flooding of a river.
