What is another word for dikes?
Pronunciation: [dˈa͡ɪks] (IPA) 
Dikes, also known as levees or embankments, are man-made structures designed to control water flow and prevent flooding. In engineering and construction, there are a number of synonyms used to describe these structures. Some of the more common terms include floodwalls, berms, barricades, dams, and barriers. Each of these words describes a variation on the idea of a raised, reinforced area that can keep water from overflowing into an area. Some of these structures may use earthen materials, while others may be built with concrete, steel, or other materials. The key characteristic of all dikes is their ability to protect against flooding.
