Rand Water
A turbine or water wheel,
In an undershot water wheel, the wheel turns as a result of the weight of the water. The water flows into the wheel, stops and then when the wheel turns the water flows out underneath the wheel. It is used when you do not have a big head of water. In the overshot wheels the water pushes the wheel and then flows over the top of the wheel. The overshot wheel uses both the weight and the momentum of the water and so are more efficient and powerful.
