Briefly explain the trade-offs that accompany any flood control project
The obvious benefits of controlling flooding are offset by loss of sediment deposition area, loss of wetland habitat, loss of the natural evolution of a drainage basin (natural changes in the stream channel such as meandering), increased soil erosion, and decreased natural ability to moderate effects of floods.
