Thats a bit of a jump. Each generation has the knowledge it gains laid on top of that handed down. How come the city is no more? Why did it collapse? The Hittite empire collapsed partly due to climate change. The struggle of the poor people is recoded on clay tablets sent to the central authorities pleading for help. The amazing cities surrounding the temples of Ankor Watt also succumbed to a changing climate. What happened to the ancient bronze age Harrappan Indus valley stone and baked brick built cities with their covered drains and sewers built when we in western europe were still living in clusters of clay and wattle houses. There is nothing unique about this city.
It really only takes about 100 years to lose knowledge. Just look at the knowledge lost just in foraging fresh herbs, plants and so-called weeds. The Indians had a crude but effective method for desalination, which isn't really talked about but we can't figure it out.
guessing that helenamcginty4920 is under 30, or possibly it's 40 when we start saying "i've forgotten more than you know". idk, i'm almost 70 and seem to have forgotten more than i used to know
There were great civilisations from before the bronze age in the middle east and Asia. The inhabitants of the cold, wet, foggy and rain sodden lands of what is now western europe were way more primitive. Read about not only the Sumerians and Babylonians but also the Egyptians, Hittites and Levantine peoples. The Asian bronze age Harrappan civilisation with its stone and baked brick towns and cities and its advanced drainage and sewer system. My history education at school skimmed over all this. Didnt even mention the great Arabic centres of learning that underpinned much of the Renaiscance after religion got in the way of learning back in the 12th / 13th centuries. Christian culture then took over in the west but in Asia both near and far their learning built on their own ancient sources. How many have even heard of the great Malian empire and the amazing Mansa Musa. The truly ancient libraries of Timbuctu. It was just a word in my childhood. Part of a saying denoting a far off place. I was a young adult before I knew it really exists. Africa isnt just where homo sapiens first evolved it is where some of the worlds oldest cities were built. Cities in the East that traded across the ocean to India and China in the medieval period. I am now old and find that I still have so much to learn. I love that I dont have to rely on out of date books in the public library but can type half a question into a search engine on the net and find more information than I can hope to absorb. Like this video. (Thank you)Its like magic.
This place is in Iran and in my city, Bushehr. In many years people think these are graves, thank you for letting us know the real story behind these piece of art and engineering
Very interesting . That entire project, if a water project, had to take a small army of people to accomplish which means there must have been a fairly large city in the area. There is probably more to be discovered. :O)
The first thing I thought of was little ponds. It reminded me a bit of the Paani Foundation competition in India (see videos on youtube) where they build a series of check dams and berms to slow the water to replenish the water table. A number of villages used to have to truck in water and these projects have since made them water independent.
Ingenuous, and fascinating. Do we have anything like this in a more modern setting? Rainwater catchment at its best, and it must have taken enormous effort to achieve. Thanks for sharing.
Really fascinating, really wonderful!! Thank you! I really hope we will develop a more cooperative society, and that we will make great use of technologies like these to make things better for everybody.
Interesting… so the system is designed to feed the natural aquifer by solving the problem of the rock face seperating the rainwater from the aquifer, first the water banks compensating for the rock face causing the rain to run off before it can be absorbed into the aquifer, and then the colloidal shutes down through thw rock to compensate for the rock not being porous or failing to absorb the rainwater into the aquifer in an efficient manner. Awesome. Very straight forward problem solving, but very efficient. Bet it was a beast to carve out though. Must have been a high-value town along the Silk Road.
You mention the water "streaming off the mountain" (I think I got that right), and the ancient inhabitants built the "wells", or possibly "cisterns", and I had a thought. As I said in another comment, water and oil, and a host of toxic chemicals were coming off that hill, so the tribesmen who lived there, at the time, built those structures to clean the water. Running water over stone is a time-honored method of removing most contaminants, and the water would easily "run" away, at the bottom, over more stone, and be collected downhill.
I'm wondering how they dug wells 100 metres deep. They looked so smooth....In another video documentary, I saw the desert palace gardens along the Persian Gulf were irrigated by such structures with water travelling underground from the mountains ...Genius.
Um the footage clearly shows a bridge and people walking across it, obviously it's a known area in the region that people visit. That being said who visits Iran.
It is hard to tell where you are. A more accurate description would be nice. I found the shoreline, but where you went, within 5 seconds is a mystery. The area was subjected to a lot of erosion, an interesting idea, since there are few places on the planet dryer than the Iranian Desert. What I find interesting is the channels that seem to have carried large quantities of water did not did into the basin of the gulf, as they did, elsewhere. The "mountains", in this region, were mostly raised by electrical discharges, a feature common around the Earth, bearing out another of my theories about the region.
Hi, thanks for the feedback, I think I will make an update giving the coordinates, it maybe a pin post on the top of this video or community post, look out for it, i'm working on it!
@@LeafofLifeWorld It looks like a piece of crust was turned edgewise, while the rest of it was slammed against the upturned portion, again, and again, then large amounts of water passed over, without reaching the sea, far south. I suspect a lot of the water was trapped underground, with all that oil, such as Libya recently found.
@@LeafofLifeWorld It looks like Nayband Gulf on the right, at 00:02-00:05, but you would have to be going southerly, to have it on the right, and it is far from Siraf. There is no body of water that matches your opening description, and the Nubo-Sindian Desert stretches along that coastline, from Iraq to the Strait of Hormuz, offering no insight.
@@LeafofLifeWorld This region, from Afghanistan to the far shores of the Red Sea, and all of the Sahara, experienced dramatic changes at some point in the not-so-distant past, with large amounts of water (liquid, at least) running off, here, into the Gulf, leaving great gouges in an earth heavily marked by volcanic ash, and countless chemicals. Whatever happened, it wasn't a pleasant experience, although none of today's inhabitants lived anywhere close to it, at the time. Whoever did, didn't survive the experience, judging by its appearance on Google Earth. Probably when all that oil was deposited, somewhere around an "ocean", if not more, all over the region, carving great, but narrow, gullies. I suspect the region "burned" for centuries, completing the process. I found the area, finally. The center of the area with the "wells" is at 27°N40' 52°E20', with a major arroyo coming down the hillside (these are not "mountains", those are behind the valley on the other side). Whatever else, the region was torn, tattered, and frayed, at some point, twisted, rotated, and the pieces slammed against one another. No one alive survived. The "water" I mentioned was likely Noah's Flood, or Gilgamesh, whomever, it's unimportant, except that it happened, if not exactly as we're told), pouring off the land masses, finally, carving those gullies, wadis, and intricately-carved slopes. Nothing else leaves the land looking that way, only massive amounts of water (and in this case, billions, if not trillions, of barrels of oil).
Very clever system. Like any earthwork, its catching run off, most of which shouldnt be there in the first place. if the ecosystem was intact and the soil surface upstream was covered with a matt of grasses, you wouldnt have this much flash flood runoff to need to catch. Holistic planned grazing would hold the water higher up in the land for longer and these divets would fill up more gradually and consistently. Indeed, they might not be necessary at all of the water gradually and slowly flowed through healthy, spongy soils rich in organic matter.
As explained in the video it to capture water and take it down into the aquifers, the water is subterranean you can't see it. You only going to see what for a very short time after raining that doesn't happen much there
Maybe the climate change needs a human response that can continue to support natural living without such sacrifice. I'm sure times could just be getting better...!
