Bill Zeedyk and induced meandering in Altar Valley, Arizona - Part Two 1-14-2012

Bill Zeedyk describing some of the aims and coming effects of volunteer-installed on-the-ground work at the Elkhorn/Las Delicias Watershed Restoration Demonstration Project site in Altar Valley, Arizona by using induced meandering within the water channel with one-rock-high baffles and one-rock dams seeded with native restoration seed mixes.
Bill also covers:
• How his approach is an integrated art of geology, hydrology, and ecology
• Baffle construction
• How sediment flows in water like a stew on a conveyor belt continually moving downstream
• What originally caused the erosion that this project is striving to heal
• Basics of one-rock structure construction
Induced meandering uses baffles to purposely nudge the water's flow within a channel to erode the opposite bank in order to widen and lengthen the channel as it reduces the channel's steepness, and reduces the speed of the flowing water and its ability to carry sediment. Sediment from the eroded bank is then caught downstream by a one-rock dam and another baffle nudging water against the other bank of the channel.
The intent of the project was to reverse the trend of the down-cutting water channels with ephemeral flow by shifting from erosion of soil to deposition of soil. It has done that. Filmed 1-14-2012 in the first phase of the project's build out.

My apologies for the loud noises in the background from the working crews moving rock and building the rock structures.

So, if this was filmed in 2012, have you perhaps got a video of how it looks in 2022? Would be _very_ interesting to see the result of this work.

Thank you for uploading.

Thanks for this. Was just searching for info on the Austins and their work with Cuenca los ojos for restoration in Arizona using rock dam structures (not sure if ORDs or something different) but when I saw your name on the video I knew it had to be good. Important information

With all the background noise its often hard to hear what bill is saying, automated CC cuts out at these points too, if you have a good idea of what he is saying at those points then adding actual CC’s to the video would be great.
Just reserved your book at my local library, looking forward to reading it.

25:30 Maybe another metaphor for resisting force together is a rugby scrum.

Is this sort of a gabion?

Hope someone pointed out to the chap the rudeness of his behaviour ...

What that Sonia?
