I wonder if some of these check dams have been raised, perhaps several times, as the silting process progresses? The point being is to increase the retention value of the silt field: i.e. extend the field further & further, back up the wadis to create a more extensive planting opportunity.
It does; but slowly enough to allow a lot of the water to sink into the earth. Also, silt that is being carried by the water has a chance to settle out.
The silt is soil. You plant in it and it makes the dams even better because the above ground plants slow the water down and the roots stabilize the soil. You create a series of terraces for planting trees, forage or other things ... and this makes the water retention even greater. This is a fairly large one because it's a large wash. You can build very small ones to block small erosion channels and work down the slope one structure at a time, stopping soil loss.
That previous reply from me was just an an accident. Please ignore. Al Bayda is doing fine with these videos and I so appreciate everything they put out as this is a world-changing project. Also it gives us the ephemeral but powerful feeling, which can stir us to action--hope. Who knows but that Al Bayda project may have limiited time or money to allocate to professional filming. Or perhaps film records of the project are not included in their mandate. If that is the case then informal archiving of this project over time is generous and priceless.
Great job love from India ❤️I wander very few people know about this channel
Exactly!
Simple yet effective👍👍👍

wonder how much strategic blasting has been done to fill ravines with boulders and accomplish the same thing at key points along a wash?
Cool vid, but that swallow at 00:03 is a paragon.
Doesn't the water just flow through the rocks or does it store water on the uphill side?
It does; but slowly enough to allow a lot of the water to sink into the earth. Also, silt that is being carried by the water has a chance to settle out.
Good job, how did you carry and move these rocks ?
One at a time, with muscle power. Carry the small ones, roll the larger ones using levers.
You pick places where gravity can help you.
Does silt have any use for anything? Filtering?
It's a first step to soil creation.

how check the Gabions and how check the Density
:) !!!!!!!
but it's clay that's waterproof?.. i'm assuming they did a study that says that water will be able to be stored in that area. :/
Quelle est la nature de ce sol ?
Sable siliceux?
Where are the Gabions?
Hes standing in the gully call agabion
Again program made 9 years ago what happening in 2020
He has new video that he made on his channel.
I think he stopped durring covid
camera work is horrible, a 4 yr old can do better....
shut up, its not the main objective in this project to have good camera work
+PeterK But perhaps now (2016) it would be time to issue a professional video documentary of the goals and achievements of the project?
09conrado yes, I agree
