Baffle blocks are concrete structures with different shapes, for example trapezoidal, used in flowing water to reduce its force. They are arranged in several rows in stilling basins. They are used in spillways and dams, in irrigation systems, to protect fishes in rivers with hydrotechnical installations, to improve sediment deposition, as a solution to scouring in hydraulic projects, and in flood control.
