River Geomorphology (41) - Double low head dam removal and grade control demo

This clip has no audio. Download the teaching guide at
emriver.com/doc...
Here we see a simple demonstration with two low head dams in place and active
equilibrium bedload transport throughout-- i.e. sediment entering the reach =
sediment leaving it, and there are no zones of net deposition or erosion.
The downstream (yellow) structure is then removed. The bed immediately
adjusts by downcutting. The incision is effectively controlled by the upstream
(blue) structure.
This shows how bedrock control or built structures can prevent incision and
headcutting. In the St. Louis, Missouri area, for example, buried sanitary sewer
lines and other utilities crossing streams often are exposed by incision in this
manner and act as grade controls.
