"River Erosion: The Wrath of Nature Unveiled"

[@chadcastle6980]

This video was made as part of an introduction to the types of things we do in Civil Engineering and was uploaded by Capture VR. The idea was that there would be a virtual walkthrough of the labs and certain areas could be clicked on and a short video would appear to briefly demonstrate some of the problems involved in civil engineering. The video is to give school leavers and parents a visual that can be understood. Obviously this is not the level the University teaches but it is for people that may have played around with hoses, dug small river beds and experimented with water as children. It also takes some of us back to our schooldays and the oxbow lakes which I did mention but lost to the edit. Hydraulics labs have Venturi meters and flumes, hydraulic jumps, pipe flow, wave energy, open channel flow and many other experiments. This was just a little taster for those that are interested. There are lots of different things that can be done on the flow table but I only got to do one scenario and I'm glad most of you enjoyed it.

It’d be pretty cool to run the experiment with different layers of sediments to show how geography impacts erosion. A Layers could be added and then flattened/compressed to form different densities to represent sediment types. Rocks place in the water stream would also be interesting. Trying to replicate the conditions that allow an Eddie to form would be tight

[@F3EDER]

@gangste Yes, it would. The Outer Banks of NC, USA is a great example of that. The sand banks quickly erode away and they planted a type of wild oat (if I recall correctly) that grows very long roots to stabilize the dunes and slow down the erosion. It is an amazing area very rich in history! Highly recommend going there.

[@jeffreyokun2355]

Exactly! What bothered me immediately was that it was made from one type of sand without layering of different earth materials and also not compacted at all. The general fluid physics still applies in that the flow will try to go through the path of least resistance and will eventually smoothen out into flowing a direct path given enough time. However one thing that cannot be seen in this demonstration is the effect the water has when it removes earth and burrows deep into the ground like in grand canyon over immensely long periods of time. In these instances the water flow slowly loses it's ability to seek direct path and has to follow the surrounding embankments because of the erosion is directing the flow deeper into ground.

This is what I did every time I went to the beach as a kid. I'd make little barriers and buildings out of sand, then get a big bucket full of water to pour somewhere and watch it all change. Fascinated me as a kid.

I used to do this with a bucket at the beach all the time as a kid. I'd make this channel for the water to travel along that had all sorts of twists and turns, and often overly-steep dams of sand because I didn't understand how dams worked (though they sometimes managed to hold the water back anyway), and I'd pour the water down and watch how it eroded and changed the course of the stream. Now, over a decade later, I'm taking geology courses in university, and some of the material is reminding me of things I remember watching over and over at that beach.

This video is amazing. When I was a kid, the flood water from the mountains was passing through a culvert near our village. In the morning I used to see such deposition of sand creating a beautiful landscape with ripples and different color of sand. Some areas with very fine sand deposition with very smooth ripples (already drained). Also we used to build small dams with soil providing pipe culverts (made out of rolled thick leaves or hollow matured papaya leaf stalks). It was fascinating to watch (I used to watch keenly) water depth rising upstream of the soil dam. Even as a child we used to make wider bases for the dam to stand the water pressure. In the mean time water used to flow through the papaya stalk culvert. At that age my joy knew no bounds watching the flow. Also we used to make a slit opening on the earthen dam, keenly watching the flow pattern down stream of the dam spreading like a fan, and watched as to how the sides eroding away gradually and widening the slit opening. We were not satisfied with that. We then tried to repair the eroded portion of the dam by digging up wet soil along with grass and grass roots from nearby grassy area and carrying with both hands to fill the eroded portion of our dam. It worked and the water depth started building up again. Some time we used to build the dam ahead of the flood water arrival. Your video brought those memories back to life. Thanks a million for that!!!

@@christianriddler5063 Pollution, Climate Change? never heard of this before?

[@christianriddler5063]

@@ChakatNightspark It was much warmer 1000 years ago compared to now. Why should we worry about some climate change? The climate changes all the time and life on earth adapts. Nothing to worry about at all. In fact through out most of earth's history it has been much warmer than it is now. Pollution of micro plastics though is a cause for MAJOR concern. Nature will be fine but us humans will not be fine. There is research that points to the fact that micro plastic pollution has a direct connection to sterility and cancer. Life on earth always adapts, it will be fine. But if we humans become sterile from plastic and chemical pollution it might become difficult to survive as a species. But hey, people want their iphones and plastic bottles right? lol, everyone gets what they deserve in the end.

Lovely. So simple yet very much educative

[@scienceholeum2181]

I teach geography as well to my students and I must say it is a phenomenal demonstration of the river flow. Learning with fun.

[@chadcastle6980]

Thank you. The sand we used has had its critics but in our case we want quick effects so that we can look at as many scenarios as we can within a lab session.

[@coach714]

I have no idea how I got to this channel but I'm studying these vids like I'll need this knowledge one day.

[@weaksause6878]

Need some gravel mixed in with the sand.

[@DuBstep115]

Yeah it was too fast. If this was the case we wouldn't have bendy rivers anymore, only straight lines.

[@chanachon56]

@@DuBstep115 I believe that's the whole idea: to demonstrate how rivers (and streams) cut it's way through the ground in a condensed time frame. If the model were to contain extra bits and bobs to better simulate real life soil conditions, then you'd be waiting a looooong time before you'd get the same results.

[@MikfinityPog]

@@DuBstep115 Well, I think tree roots play a big part in preventing erosion in rivers.

[@Keldaria68]

@@MikfinityPog they do, as does vegetation in general. The real driver of erosion is also how much water we put into the system. Something which has been increased significantly in urban watersheds driving higher erosion down stream due to water depth and velocity as the river seeks to find a new equilibrium. Bedrock is another important factor in many areas as it keeps the river from incising and causing excessive erosion from steep banks.

[@oddities-whatnot]

Concrete. We could watch this for decades, it would give us something to do in the never ending lockdown.

[@orangeframe1093]

these are the videos that peak my interest enough to keep me up to 3am

[@FireFox2382]

The crazy thing is we are able to capture similar patterns on Mars! It was highly likely that Mars once had rivers like these

[@michaelmensah40]

You are a very good instructor. I enjoyed watching the video and it was very educative and informative. I have watch similar videos but your experiment is better and makes more academic sense. Thanks for the effort you put in.

[@chadcastle6980]

Thanks Michael, guitar videos next? 😁

[@OutThereLearning]

Nice. would be great to make a portable one to take to different schools

[@originalname6231]

Very interesting

[@connclark2154]

If I would have known I could have been paid to play with dirt water and toys I would have stuck with it when I was 5.

[@jamesmclemore9123]

I like how they have little trucks on the bank like it's a tiny construction site

[@Torantes]

They look so cute)

[@revimfadli4666]

With construction taking so long that the river changed course during the time

[@gteaz]

He could have used the trucks to build walls to stop the banks from collapsing.

[@goldnap7836]

So, I can see the process of making oxbow lake. I learned it 30 years ago in my elementary school. Now I can understand whole process. Thank you very much.

[@sinisterdragon]

Great demonstration of how a "Billabong" forms... Fantastic experiment...

[@ANMA133]

Which is why trees are so important as their roots help prevent erosion

[@emrebennett2857]

Which is why wolves are so important. They keep the population of deers down so they don't decimate all the Riverside trees

[@Panzermeister36]

@@emrebennett2857 Deer don't eat trees. They eat bushes. Trees that have large enough root systems to stop erosion are too tall for deer.

[@emrebennett2857]

@panzermeister36 Nope. There is actually a real life example of where they had to reinstate wolves into a wildlife reserve because the exact thing I mentioned above happened. Remember that dears also destroy trees and banks through other means and more importantly they eat the treas when they are in sapling - bush stages

[@MoneyManHolmes]

In the river near where I live, the erosion occurs below the roots and they just fall into the river. I guess it depends on the depth of the channel how much they help. The main way the local land owners stop the erosion is by dumping discarded chunks of concrete down the bank until it’s built up above the water level.

[@ANMA133]

@@MoneyManHolmes mangroves are the bets type of trees to stop erosion as they grow in the water itself.

The cars are making me want to play with the river

[@kazkorianor]

i need to build that for my living room and watch it XD that is just nice to look at

[@ZoidiusPlasmaReaper]

KZbin Algorithm blessed me with the showing of this video. Entertaining to watch and learnt something today. Thank you.

[@TomPatricks]

I've been discovering this erosion on a medium scale while playing with my yard's drainage flow. I have managed success in commanding flow from 4 feet front of the yard all the way in to the back of the back yard. My 4 foot front parameter is demanding a higher resistance due to the elevation of the property relative to street level. Rambling. I apologize. Thank you for sharing this video with me! I feel I have learned a lot and I'm certainly going to review and subscribe, too.

Playing with rivers in the sand like this is one of the big reasons I went into civil engineering... although my playing with Legos background ultimately won out and I emphasized in structural engineering. Great video!

[@dragonmeddler2152]

So now you do college-level research to learn what I learned as a 7-YO in my backyard sandbox with mom's garden hose...

[@thehillbillyhilton3557]

Lol right. Sand or dirt and a water hose= endless fun + educational

[@gregwarner3753]

Did lots of experiments in a sandy parking lot after a thunder storm as a 10yo kid. Learned to put it into numbers in college.

[@CarangaGA]

This is probably for showing people from outside the college dumbass. Its a common thing in colleges, making didatic experiments for the average population

[@cjvilleneuve1566]

exactly, so it mean as a child i was a water drilling expert , sending meters of hoses under ground until it pop out a distance away.

[@fryloc359]

I know my mom got REALLY mad when we played with the hose like that.

[@chris-thumper7205]

Water is just like electricity. Takes the least path of resistance. Great video explaining this.

[@CamoSquid]

Not sure why this was on my reccomended, but I'm not complaining always have loved this type of stuff, and I'm now going to start looking for more. Would be cool to see a completely flat, or even randomly placed bit of sand like this, and just let the water do it's thing, to create it's own path
