What type of fall does the diagram depict?

What type of fall does the diagram depict? Correct Answer Ogee Fall

The diagram shows that water is gradually led down the convex and concave curves. It also shows the draw down on the upstream side which results in lower depths, higher velocities and subsequent soil erosion. The curves provide smooth surfaces which results in less energy dissipation, which again causes soil erosion. Hence the diagram is ogee fall type.
