What is the purpose of a dike?

A dike, also known as a levee, is a structure built along rivers, coasts, or other water bodies to serve various purposes:

• Flood Control: Dikes are primarily constructed to prevent flooding by confining the flow of water within its boundaries during periods of high water levels or heavy rainfall. They help protect adjacent areas from inundation and reduce the risk of damage to properties and infrastructure.
• Erosion Control: Dikes can also help control erosion by stabilizing the banks of rivers or coastlines, preventing soil erosion and loss of land due to water flow.
• Land Reclamation: In some cases, dikes are built to reclaim land from bodies of water, allowing previously submerged or marshy areas to be converted into usable land for agriculture, urban development, or other purposes.
• Navigation and Water Management: Dikes may be used to manage water levels in rivers, canals, or reservoirs, aiding navigation by regulating water flow and maintaining desired water depths.

Overall, dikes play a critical role in managing water resources, protecting against flooding, safeguarding land from erosion, and enabling human activities in areas susceptible to water-related risks.
