Watch An Oxbow Lake Form: Ucayali River: 1985 - 2013

- This series of Landsat images captured between 1985 and 2013 shows the meandering Ucayali River. The high sedimentation load of this very active Amazon river causes cutoffs and an oxbow river as the channel changes course.

The small river on the left side is pretty cool to watch too.
what! it literally disappeared in a year, can anyone explain what this phenomenon is called
Justin Chow I’m not sure, but if you look at the years 2005-2006 (0:52), you’ll see that there was suddenly a lot of sediment deposited at the northern end of the smaller river which ultimately resulted in the smaller river changing course and joining with the larger one
@@thewhopper256ify Maybe it was man made change or something
@@theovicenty18 no, more likely is one particularly more rainy season, bringing in more silt from upriver. There is absolutely no sign of large man-made works in this timelapse whatsoever
The fact that it completely changed direction in such a short time is astonishing.
What I find really interesting is that the lake continues being fed by a small inlet and drained by a small outlet
Just doing lake things 😌
@@plowe6751 Oxbow lakes by definition need to have water if they dry up they are called an "Abandoned meander" so yes it would dry up if it didn't have that.
This is a beautiful way to show how alive rivers are. I think that the amazon is an exceptional landscape, and it rests on an incredibly level piece of land where this type of rapid change can exist, which is why the sediment can build up and block off previous paths of the river to allow new ones. You can see it so clearly in this video.. The path to that section of river where the water flowed was eroded away little by little until they connected to each other, and then bypassed the loop altogether. then the path of least resistance became straight and you can literally see the depositing of sediment building up where the majority of the water bypassed, eventually cutting the loop off almost completely from the river. This type of stuff is fascinating to me. I absolutely love how water flows and how rivers form themselves. If I could find a way to make money off of studying this I would do it in a heartbeat. Its so fascinating!
Oxbow lakes are formed when a river's meander
gets too wibbly, wibbly, wobbly to maintain the course it's on
The main flow of the stream diverts itself accordingly
Wtf🤣🤣🤣🤣
It must be due to deposits on the opposite side of the meander. It causes the river to cut towards the meander, thus changing its course?
but here's my question son....
@@brynnp1165 What the hell's an Oxbow? Are our bovine friends fashioning weaponry? Someone should tell me; Do I need to buy a shield?
Thank you so much for posting this. I come across the term "oxbow lake" in my reading and this completely explains what it is.
Same here!
Fun fact: in Australia they’re called Billabongs.
I come across this as I browse google map, and found traces of river that seems to be cut off of the river with weird shapes. Turns out river loves to change it's appearance dramatically
samee
@@spacedoutorca4550 Another fun fact: In Brazil they are called "Braço morto" [bɾä.su moh.tu] which translates to "Dead arm" (Literally "Arm dead").
Woow everything is perfect
Short
Good soothing bgm
Good graphics/animation
Awesome
Reminds me of Amoeba
I wish most videos could be this succinct.
The perfect video to watch while drinking a glass of water after waking up at 2am before going back to bed
I was looking for the time it took to form. I didn't know if it was a decade, a century... This video gave me a nice perspective. It is fast enough that people would grow up and notice the difference
This is very interesting to watch! Shows how rivers are almost like a cycle!
I feel so sad for that ox bow lake..!
Huh?why?
I was going to say the same thing! the music makes it sound like he got left behind!!!😢😢
We got people being sad at oxbow lakes before GTA 6 🤪🤪🤪
@@HurricaneForceOk, they’re sad, but are you implying that we are only supposed to be sad for oxbow lakes after GTA 6?
@@anthonyschocke2831 just a joke
Thank you for the posting this,😁😁

Something I want to add, to go along with the 10km scale in the lower left, is that Landsat has a resolution of 30 meters. Every pixel here, 30 meters. This river is BIG.
If you're wondering why the pixel size is so big, two reasons. One is continuity: Landsat began in 1972, so though other features are added and the spectral bands focused on are fiddled with, the resolution remains the same. 52 years later. It is still an improvement over the first few which had a resolution of 60 meters. The second is that the the scanning imagers on them prioritize speed and coverage over resolution: Landsat satellites cover the ENTIRE Earth every 16 days, giving them much better temporal resolution than basically any other imager up there. I'm simplifying a lot, but it's one of those things that we take for granted but took a lot of people a lot of effort and good thinking to set up and keep going uninterrupted. Landsat is cool.
it's really cool and fascinating. im trying it myself with the google map time lapse
The music makes it so sad, like a pixar short.
It’s more like lofi hip hop
The uycali drifts a lot! You can visualize its entirety on the google earth engine’s timelapse function, check it ou!
Thank for posting it
Absolutely fascinating
Cool part is that you can see an even older oxbow lake to the right :P
Very cool!
The top left thing was adjusted and it also formed an oxbow lake in 2018
That’s so cool and satisfying
So calm I love it
That's was beautiful
Thank you
Looks like the meander was too wibbly wibbly wobbly to maintain the course it was on.
I just saw an almost identical video of the Coosa River that was from 1985-2010.
I like the music on this one a lot
That's quite fast. Worry when thinking about river in my town
Eu não imaginava que o processo fosse tão rápido, incrível.
Thanks dude
Cool!
Oooh thanks for this I have a geography exam tomorrow and this is in it
how it does not dry? also all the fish left behind.
Props to the cameraman
thanks mate
No
WAWAW
Best video
So cool. Everything is alive
On the left side it's starting to form another oxbow lake
Very good
Good old Kevin McLeod audio. I swear it sounds like a popular song that I can't quite remember.
Oxbow lake
Wow it happens faster than I had originally assumed
How long do these lakes usually survive
It depends, but not long
@@Ptaku93 u mean the oxbow ones?
Muy interesante 👌🏼
Thanks
nice one
Cool tune
Imagine leaving your house for 10 years
Please share the background music please!!
The small river on the left half of its body of water evaporated cause of tempatures due to sunny reasons
Why is no one talking about the entire stream in the top corner completely moving
COOL
I always wonder what the natives thought of these phenomena. It’s definitely observable in a single human life so I wonder how they explained it. Or if they already knew how it happens.
thx
And they say nature doesn't have a mind of its own, yet it always manages to seek a pathway of least resistance, find efficiency where inefficiency is found.
even river is a living thing, this world is a living thing
0:51
Where 2004 at?
It happens for soooooooooo much time
cool
River meander gradually to oxbow.... 👌
Am I the only one who didn't know we satellite images from the 1980s?
1:00
satisfying
It made a private little Peninsula.
I learned this in school
Title says "oxbow lake," description says "oxbow river." Very confusing and inconsistent.
👍

Why don't they dry up tho?
No they dry up eventually but it takes some time.
Прям америку открыл, у нас такого везде полно
*oh my god thats actually really cool*
The rivers in europe are way too "well maintained" for this at least of the used waterways. If you look at northeastern russia and siberia though, youll be amazed by that alien-looking landscape. If you look at map images on some parts of europe though, in fields you can clearly see sometimes huge areas where the residue of old rivers settled in the many thousand forks it created for hundreds of years it existed.
crazy

hello class
This is why it's a bad idea to base borders on rivers.
🐂🐂🐂🐂🐂
Look! Look at the "supreme being" personally digging trenches.....
what is this haram ting
damn 1995
wow
