What are the differences between a sluice gate and flood wall?
sluice gate = open a sluice and and let out water; drain; release a flow of water, flood; wash in a sluice; send through a sluice; flow through, flow out Flood wall (There is no gate) A flood wall (or floodwall) is a man-made primarily vertical barrier designed to temporarily contain the waters of a river or other waterway which may rise to unusual levels during seasonal or extreme weather events. Flood walls are mainly used on locations where space is scarce, such as cities or where building levees or dikes would interfere with other interests, such as existing buildings, historical architecture or commercial exploitation of embankments.
