Why do Rivers Curve?
Вставка
- Опубліковано 20 чер 2022
- Rivers become curvier and curvier until they bump into themselves. Then, lakes follow the route of least resistance and connect to form a straighter route. What’s left over is called an Oxbow lake… but they go by a lot of different names.
In Australia they are referred to as Billabongs; in South Texas, they are called resacas, sometimes they are called ‘horseshoe lakes’.
Do you have a special term for them in your country?
if anyone is wondering, they give because:
Higher speed at outside corner of bend, causing erosion
Slower at inside bend, making deposition
It is deposited and eroded to a side, which makes it curve
It's this and the ground is made of different "hardness" of soil/rock. Essentially the water finds the path of least resistance through softer rock and soil which forms the bends in the first place. Otherwise water would just run in a straight line from source to the sea.
You should've been the one narrating the video instead of her 😂
Why does a bend form to begin with? Also aren't velocities on the outside of a bend slower? It's like how a planet orbits faster if it is closer to the sun.
@@jay1373theres already a comment in this thread explaining the first question. But the second:
The reason mercury travels faster is because of the gravitational pull of the sun. It wouldn't really be applicable here, since gravity is pulling down, not in.
Instead, we have to take inertia into account- "objects in motion stay in motion." Importantly, they go at the same speed in the same direction until acted on by outside forces. The fastest moving water wouldn't turn sharply to go along the inside of a bend, but would continue straight until forced to bend by the outside curve
The full video did cover it I think (years ago since I've seen it), it's an unfortunate short. Awesome that you took it upon yourself to explain it.

No. Rivers form oxbow lakes because they curve.
Cause and effect cannot be swapped.
@@cush6827 Yes obviously. They're making a joke about how the videos title is "why do rivers curve" and then instead of answering that question, the video just tells you that when they curve a lot they make oxbow lakes.
@@cush6827 You missed that there can be a higher , "teleological" , reason , as already pointed out by Aristotle: The entire reason why our Demiurg created rivers was because He knew of no better way to make oxbow lakes. 🤪

I'd assume it has to do with Rivera slowly eroding their banks and then naturally flowing to the lower points

I think their why question was meant to be rhetorical
Now, this made me wonder what happens if a river curves into one of these lakes.
I remember i had to learn about Oxbow lakes in school and no matter what, i DID NOT understand it. I ended up eventually mugging up the meaning, this would've been so helpful back then
Same!
Hilarious but mostly sad how bad schools often botch up teaching you even pretty simple concepts 😓
Explanation: Any original curves grow due to water pushing against the outside bank and eroding the outside, and then water moving away from the inside bank depositing sediments.
I didn't understand any of that but that looks like a good explanation
@@Dahackabarade water makes hole on outside curve and puts down dirt on inside curve
It’s funny how so many people literally can’t do enough thinking to understand that this is what she meant
@@Dahackabarade the water erodes the dirt on the curve its pushing on and the dirt on the part where it aint pushing on gets filled with dirt, kind of similar to how a ship pushes through water at the bow and water gets pushed away while water at the stern fills the void left behind by the ship
why is it eroding one side rather than just eroding straight ahead though?

Basically (here’s what I’ve learned from GCSE Geography), the flow of the river grinds along the outside of the meander, eroding it away, until it cuts out a “river cliff”. This river cliff becomes unsupported as it is eroded underneath and collapses. This happens over and over, causing the meander to recede, but the river on the inside of the meander travels slower, and so it loses its energy and drops the sediment suspended in the water (known as deposition). This follows the erosion outward, and it creates a “slip-off slope” that’s slanted toward the river. When the two meanders meet, the water takes the most direct path, or the path of least resistance, where loss of energy travelling through the meander causes deposition. As the river is cut off from the meander, this leaves behind an ox-bow lake that is often dry with little water, unless it is in a floodplain, where a flood will occur filling the ox-bow lake and the water remains there after the water is drained away.
This is from what I learnt, and I’ve just finished my GCSEs and an ox-bow lake question did not come up :/
Though I am still looking at a decent grade, hopefully. I’ll see on results day in a few weeks, won’t I?

@@Fitz1993 not explained though
My guess is the curves get more erosion from the water constantly hitting the outer sides, making the curves more pronounced over time.
@ComaradComisar pretty much the water on the slightly long curved edge has to move faster to keep up with water on inside edge causing more erosions on that side.

@@zescare2652 nah its caus your brain wants you to fell pain so you know its there
Heres an actual explanation for you guys
When the river is first forming, the water will take the easiest path downwards. If all the rock was the same, that would be a straight line, but some areas of rock are weaker than others. The water erodes that weaker rock faster, and so it takes a slightly winding path
Now that a slightly winding path has been established, the curves will start to grow. This is because the current is essentially smashing into the outside of each bend, causing those to erode more. The inside of each bend has a slower moving current, which causes sediment (like sand and gravel) to settle there.
The rest is as you see in the video
That's all they could of said. Instead they say once it's curved it continues to curve as if the curves magically appear
Edit: idk why yall so mean, I don't know why the curves begin in the first place. I want to learn and this little clip really didn't help at all, sorry I'm dumb lmao

“Why do rivers curve?”
*“Yes.”*
Edit: its been a year, and people still don't realize its a joke 💀
Erosion is stronger on the curves
This was taught in middle school.
Water on the outside of a curve has further to go and so travels faster, while at the inside of the curve the water travels much slower. Higher speed water has more energy and so erodes the rivers banks and beds. Meanwhile lower speed water at the inside of the curve doesnt have enough energy to transport the eroded material and so deposits it into a fresh bank.
Calm down hes not in middle scholl yet probably
Not every school in the world teaches the same stuff and trevor's right that the video fails to actually answer the title question.

@@itsiwhatitsi like "i cant sniff" floydy followed the W Cop and got punished
Rivers get twisty because fast water erodes the outer bends, carrying away dirt and sand, while slower water deposits these materials on the inner bends. It makes the bends more pronounced over time.
The fastest moving part of the river is on the edges, as all the silt is trapped on the inner bank of a turn. This keeps the further bank more eroded growing through time as the video shows

"Why the rivers curves?"
"Because they do"
Erosion
Oxbow lakes are formed when a river's meander gets too wibbly, wibbly, wobbly to maintain the course it's on.
The outside of the meander is faster, causing it to erode at the rock making it bigger, the inside loses momentum and drops off what it is carrying making the inside build up.

This actually helped so much more than how they showed it in school!
Also, for those of you wondering why it curves, it’s because as a river runs, it scrapes away at the “walls” of the river, and there’s more force at curves, so it gets scraped away at, or eroded quicker

In case anybody is ACTUALLY wondering why rivers curve, it’s because if water hits a spot on the rivers bank it essentially bounces off that spot and goes faster towards the opposite bank, well when it hits that bank it bounces to the next one, and so on and if you follow the angle of the “bounces” it creates curves as the water wears away the ground (sorry if I didn’t explain it very well, if you see a diagram it makes a lot more sense of course)

This is the only thing i remember from school about rivers
Each river starts high and ends low. Thats why it is flowing. It always takes the easiest way. If the easiest way was perfect straight it would not form curves. But its never perfectly straught and even at small natural curves the current takes land away at the outer side of the curve (more abbrasion than at the inner side) and therefore naturally enhances the curve further. A little bit downstream the eroded stuff sediments which leads to a curve in the other direction. This is a self enhancing effect.

Think about where the water is pushing in the bends, combine this with the fact that water erodes the stuff it pushes on and you get curvy rivers.
But it doesn't explain why the original path is sealed back up, sure it erodes but how does the original path restore to ground level?
@GeezSus The water is carrying sediment. Water on the outside of the curve travels faster, eroding the outer edge and pushing the meander further out (this is called a cut bank). On the inner edge, the water flows slower, allowing for suspended sediment to deposit onto what is called a point bank. Over time this causes the form of the river to “meander.”

“Why do Rivers Curve?”
“Well an oxbow lake is made by…”
It's erosion and sedimentation. The river digs away at the curve, curving it further. Sediment can also be deposited at the inner end of the curve.
Side note: oxbow lakes may also happen when floods or higher water levels create a new, straighter path for the river.
(This is what I remember from Secondary Geography so might not be 100% accurate)
