Background
The flood control project mainly uses engineering measures to 'block' the attack of flood on protected objects. For example, river levees and lake levees are used for defending flood of rivers and lakes; sea tides are prevented by sea dikes and tidal barriers; and protecting the low-lying area from being invaded by flood by using the dike. The use of functional flood protection is the oldest and most common measure. The flood is defended by a blocking method, the conditions of natural release and regulation of the flood are changed, and the natural flood level is generally raised. The flood level of some rivers and lakes has larger amplitude, and the flood level has a tendency of increasing continuously due to the influence of natural evolution such as sediment deposition and the like and activities such as human development and utilization of flood areas and the like; the general dike lines are long, the choice of dike building materials and foundations is small, the structure cannot be too complex, and the dike body cannot be too high. The protection against flooding by means of baffles is therefore subject to certain technical and economic limitations.
