Keyline® in the AR Sandbox #3: Design for Water

- Welcome to this 7-part video series that is excerpted from Oregon State University's Online Permaculture Design Certificate Course:

The Keyline® Plan is a method of land design for soil and water conservation developed by Australian farmer and engineer P.A. Yeomans in the 1950's, and practiced widely throughout Australia ever since. My training in this design system came from Keyline® design's modern day emissary, Darren J. Doherty of the Regrarians (www.regrarians.org). This series is my best attempt to present a simple introduction to the design system, beginning with the very basics: understanding landforms to determine the potentials that each landscape possesses.
There are a lot more design layers to this system then what is presented in this 7-part series, so please treat this as an introduction, and not a comprehensive explanation. I also refer to other videos within this series that are part of Oregon State's Online Permaculture Design Certificate Course and are not publically available, so if you want more depth in this topic and others, please visit our course offerings:

What an incredible educational piece! Thank you for explaining this so clearly.
Best key line presentation I have seen. I got it for je first time after studying permaculture for 10 years
Thanks and that means a lot to me. It took me having a workshop with Darren Doherty before I was able to grasp it in 2007. It is somewhat of a complex equation!
Hi Andrew thank u for your reply. I would love to chat to you about a possible collaboration. We have an online course on water and dome home building. And would like to know if we can share it with your students at 50% comm back to you ? Www.bioveda.co/domehome we also have the courses separate water / dome
Wow! I’ve been trying to understand Keyline all day, and wishing for a sandbox demonstration. This is amazing. It’s all clicking now.
Excellent presentation; I feel like I am finally starting to understand this concept after much confusion from other sources.
Thank you for uploading these!!
Hell yes! Just found your TH-cam channel. Seriously awesome.
Brilliant Andrew Millison! Awesomely clear, coherent and professional. Very helpful.
This is rad, thanks.
Very clear explanation. Thank you
Very helpful explanation, thanks again.
Thank you this is so helpful and really easy to follow. Much appreciated.
Wow...this is a wonderful simulation and presentation. I am reading Yoman's book and this simulation clears many important concepts presented in the book. Thanks for sharing this video. Hope to see more from you in future. God Bless you!
Glad to help. That book is very difficult to get through and understand. I read it multiple times, and finally understood the system after learning with Darren Doherty of the Regrarians, who is the foremost Keyline teacher in the world.
I am new into farming .. you made things clear and easy to understand. Thanks for sharing this critical info in farming.
Very helpful! I wish more math was involved, it seems like key points could be described really quickly as inflection points in the elevation curves.
"I wish more math was involved" is not a sentence I ever said in my life
Get thee to a hydrology course!
Its true though, in fact PA Yeomans explicitly defines them as inflection points. However, Andrew is trying to be understood by everyone, not just those of us affected by mathbrain syndrome :P
Thank you very much for sharing this awesome approach and knowledge. Keep well and stay blessed!
Excelent job. I have watch many of your videos and helpme a lot. regrards from Colombia.
Thank you.
These presentations are fascinating and I was wondering how you do this with active modeling of the waterflow?
Understand there's quite a bit of regulation, but to speak of this almost excessively risks putting people off when this is well worth doing!
do you have any thoughts on dumping massive amounts of brush down into a primary valley over years? Is this problematic for some reason? Will it build out the ridge over time?
I saw these mini canals in Bali
SO ON THE UPPER RIDGE COLLECTION SYSTEM, DO YOU BUILD THE CATCHMENT SYSTEMS OUT OF CLAY TO RETAIN THE WATER AND MANAGE SATURATION THAT CAUSES MUD/LAND SLIDES???
Andrew, I'm curious if keyline design was used for the MJK vineyards? I'm in an area with a lot of vineyards and they are mainly conventional monocultures, with rows going vertically for ease of tractor use.
The MJK vineyards are on-contour terraces. At that time I did not really know about the option of sloping those terraces towards the ridges, but that would be interesting to see.
Hi Andrew, I love your videos and your work and I love that some of you videos have subtitles or are dubbed in Spanish so I can share them with my people back in Chile. Talking about Chile I have a question, This model with key points is applicable to all hills? my family has a hillside property and I was trying to design some ponds but I can’t find a key point in my contour map. I wonder if I’m doing something wrong or there are exceptions to this model. Hills in my country looks don’t like bells. I’m hoping you’ll see this comment…😊
@1:04 a key point is an inflection point in mathematics.
7:26 the green lines are keylines that divert the water across the ridge?
what is the difference with swales? do swales go along the contour lines, or do they gradually descend from one contour line to the next?
The green lines represent the cultivation pattern. So that could mean how a field is plowed, or it could mean the orientation of orchard rows. They are now swales, but just the pattern by which rows of crops or cultivation lines are oriented.
In the wider world, a swale just means a low area where water flows. But in Permaculture-speak, a swale usually refers to a water harvesting ditch placed on contour. I like to use the terminology of "on contour" or "off contour" swales, because then that can be understood by people who only know about permaculture and also people who are fluent in the language of civil engineering and landscape architecture.
@@intrepid-crossing2356 There is a ton of confusion out there so that's why I say on or off-contour swales. Keyline is a very specific set of methods and people throw the terms around without really having a grasp on the terminology of the *trademarked* system. In the Keyline design system, water management structures are typically sloped from valley to ridge forms. On-contour swales are level in the landscape. But which strategy to use depends a lot on your soils, climate, and rainfall regime . There are two primary sources I would refer you to: www.amazon.com/Water-Every-Farm-Yeomans-Keyline/dp/1438225784

Woow........
What if these high keypoint ponds end up creating a spring somewhere down the landscape that is destructive to a building or something.
What do you do on very flat land?
So why put the cultivation lines off contour? It seems like it would lead to erosion and hollowing of those rows. Why not stay on contour and make the water soak in?
It’s probably not in your capacity, but a smaller scale project would be wonderful. 8-16 acres would helpful. It’s probably easier to implement then larger municipal projects.
1.5x speed still sounds like normal talking speed
Glad I live in Missouri. Just dont flood your neighbors yard and build under 35 ft.
Don't like the use of ponds. open water means you lsoe water to evaporaiton. Much better to let water go to groundwater. Also is this meant to be the surface of the earth the O-horizon or the bedrock?
You said "peepoint"
Key point!
