Headcut in a Straight Channel
Sediment is removed from the lower end of a straight reach causing one or more headcuts to travel upstream. The first headcut is emphasized with an arrow that fades as the headcut becomes indistinct. As the incision progresses the channel begins to meander and form bars/terraces and the channel evolves. Use the pause control in this short clip to take your time looking at these forms.
Good short illustration of headcutting, incision, and subsequent channel evolution.
