A spillway is an important part of Dam. The function of the spillway is to prevent overflow in a reservoir. It releases pressure from Dam due to increasing water flow. The spillway has three parts in which the approach facility permits the flow of water to the spillway. The water is carried from the approach facility to an outlet structure through the discharging conduits. The last part is the tailwater channel (outlet structure) which disperse the excessive energy of the flow downstream.
