Basinwide flood control system by combining prediction and reservoir operation


Another nonstructural option is to operate the flood control system appropriately with a view to reducing flood damage.


In this paper, a flood control system combining the runoff prediction model in the whole river basin with the reservoir operation is discussed.


A flood control system was first implemented in the 1920s1930s after major floods.


And, a flood control system that is OK on average is not much use as a protection against flooding if its weakest link is pretty bad.
