How to read whitewater

Attached is a diagram that depicts how various whitewater features are formed as a rock is gradually covered by rising water.  This is fundamental to understanding how to read water and how to read the river when kayaking, canoeing, or rafting.

These images are a side view from water level.

The DVD river runners edge has a water reading segment that nicely demonstrates how this works.  For teaching, the sketch works well because it takes away ambiguity.
