An undershot wheel is a vertically mounted water wheel with a horizontal axle that is rotated by the water from a low weir striking the wheel in the bottom quarter.

Vertically mounted water wheel that is rotated by water entering buckets just past the top of the wheel is said to be overshot.

Typical overshot wheel has the water channeled to the wheel at the top and slightly beyond the axle.

Backshot wheel is a variety of overshot wheel where the water is introduced just before the summit of the wheel.

In many situations, it has the advantage that the bottom of the wheel is moving in the same direction as the water in the tailrace which makes it more efficient.
