Earthen walls, also known as dikes or levees, are structures made from compacted soil and other natural materials designed to hold back water, particularly in coastal areas. These barriers help protect land from flooding and erosion caused by storm surges and sea-level rise. Dams, on the other hand, are larger structures that can store water and control its flow, while pumps are often used in conjunction with these systems to manage water levels and prevent inundation. Together, they form a critical defense against coastal flooding and climate change impacts.

How can dams control floods?
Dams hold back water up to the level that they were designed for. They control/regulate the flow of water. Flood waters that come down rivers can be held back (up to the design point) from devastating places further down river. Coastal/sea flooding would not be stopped by dams - but sea walls and the like. Still, preventing river flood waters adding to coastal flooding might help the situation.
