IECA Instructor Dave Derrick of the U.S. Army Corps of Engineers in Vicksburg, MS talks about the different techniques employed on a particularly tough stretch of Duck Creek on some parks ground in Davenport, IA. This particular phase of construction was done in the summer of 2008.
Highlighted stream restoration techniques/BMP's in this video include:
- Longitudinal Peakedstone Toe Protection
- Self-Launching Stone
- Locked Logs
- Bendway Weirs
- Live Staking
- Keyways/Living Dikes
Speaking from a non-engineer's perspective, geomorphology and stream restoration really need to be experienced in the field for a quality learning experience. Seeing different techniques in action is really where the learning begins. If you've never had the opportunity to hear David give a presentation, or participated in one of his many in-field learning opportunities, you definitely want to try and catch one. He's one of the very best!

Where are the BMP's when they dumped the rock in the stream-I assume these are downstream?
