They commit a blunder while construction those buns. There should have been a slight gentle dip in the middle of the bun for easier water pass over the bun and not push and damage it. These types of buns are not meant to block waters but rather to slow down the flow of water and allow water to percolate and arrest erosion.
You are so correct. It is a sophisticated skill and young ITI graduates should be interned in its making. More films on all types of dam brush wood onwards must be made available in local context for better land use and management.
very clever use of string and sticks. Great low-tech techniques to measure things. Very systematic approach too, to avoid waste and to measure outcomes.
Would it be better to put a low point in the middle of the the structure to allow oversplill rather than washing away the sides? This would need some rocke to act as scouring on the downslope. Looks very steep, a lot of potential energy there.
There's a major flaw in this design: the top should be curved so the middle is lower than the ends to prevent overflow water from undermining the ends of the structure. The difference in height between the ends and the center should be determined by the amount of flow that the stream gets to be sure the difference is great enough. A lesser flaw is that the foundation should be set in gravel pounded firmly, with more gravel filling between the boulders. Additionally, the slope of the downward side should be shallower if the slope of the waterway is steep. This makes it surer to withstand collapse from erosion at the structure's base. This can be enhanced by seeding a suitable clover or similar groundcover plant on the downstream side in order to trap sediment at the base.
We want see this place how it becomes after 5 Years? and if it's possible during the rain season. I am writing from Algeria 🙂
The addition of deep dry wells with a lot of void would compliment this very well.

Thanks for sharing excellent sample of use of knowledge and people participation on mitigating everyones problem.

with due respect, it could well be a tick box exercise. All procedures followed efficiently but effectiveness?
Excellent video, this was helpful to learn about creating bunds. Thank you
Nice! 🙏👍
Very nice
You can tell who are the bosses and who are the wage slaves in this video.
Police are helping the Geo Department. If forest or agriculture Department's get more evolved that will change everything.
Genial
Have you estimate of this check dam??? Also We required lbs and gabin estimate for-2021-2022 years
3 guy make mesurements and coordinate 2 guys work
Why dont they use lime paste to secure the stones together?
The idea is not to stop the water but substantially slow down and arrest erosion.
sarebbe più comprensibile il commento scritto
Strong accent of the narrator takes away from the report content.
What are you talking about? Her English is very good and there is no problem understanding. Her grammar is better than some Americans 😂
