Some years ago, there were many of these wheels in Morocco, but today (1995) most of them have been destroyed by floods.

The same wheel as in [38]. The rim consists of 48 boxes, each with its inlet and outlet. The river runs from right to left. The boxes on the left are filled with water and those on the right are empty. The latter are on their way down.
