Leaky weirs and landscape rehydration
Вставка

- The Mulloon Institute strives to restore landscape function. They carefully plan and design structures to fit neatly into the landscape. One example is the leaky weir.
These leaky weirs are built from natural materials such as rocks, logs, soil and, importantly, vegetation which, among other things, binds the structures together.
The structures are designed to raise the water level of the stream, and to slow and filter the flow, giving it a chance to infiltrate and recharge the groundwater.
Coupled with improved land management, these rehydrated landscapes provide more reliable stream flows and improved water quality.
During wet times, the flow spreads out across the floodplain.
In dry times, the water flow remains beneath the surface and replenishes the creek.
This allows for enhanced agricultural productivity and improved conditions for wildlife, and gives us rehydrated landscapes that are more resilient to climatic extremes.

Hi: Greenlee County, Arizona here. Although it's complete desert here, this makes a lot of sense for turning it into a lush desert versus a desiccated one.
Thanks for sharing this! I found it very helpful🙏🏼💗✌🏼
That's called being a land whisperer from a man who lived as a horse whisperer.
This method makes so much sense. It will cost much less than having to do damage control later. Why has it not been adopted on a national scale?
Because capitalists don't become rich by investing in the future but by investing heavily in the short term. Rebuilding water tables takes years, and capitalism doesn't have time for that.
It is better to repair the land slowly, over time. Less chance of catastrophic washout, less work in one go. Small and frequent is better than monolithic, tall sructures. Replanting hillsides with trees that are too steep to safely do water catchments and means the deep living roots will retain soil and lessen chances of landslides.
I genuinely wonder, what's the difference between the old and the new method, apart from creating those leaky weirs? If livestock is fed upon these areas, how does this not make the vegetation dissapear the same way it did and so the sustainability of the ecosystem around the river?
I mean if vegetation is eaten by livestock, no leaky weir would make a difference since there would be no vegetation to retain the water, or am I wrong?
@Tomislav Vrban I think I understand a lot more the base of this natural mechanism, you've explained it very well, thank you!

These destructive agricultural practices can be seen the world over, then we act surprised by desertification.
