Sooner or later they’re going to become meander scars or oxbow lakes, when the river reconnects with itself.

Holy fuck that oxbow lake schematic on wikipedia looks earily like a vessicle coming of a piece of membrane

The only thing I know about vesicles is that microvesicles are gross… thanks to paleobotanist Dr. Ellie Sattler.

My first thought when seeing this was future home of an ox bow lake
shalafi@lemmy.world 6 months ago
And not far future! Both bends are within a couple of trees in missing each other.
For those not on the water much, see the beach on the left of the top bow? The opposite side is where the water is deeper and faster. It’ll chew through that bank and meet the other side soon enough.

See those “punch points”? The river will eventually form meander cutoffs, and become a sinuous system rather than a meandering river. This will lead to localized increases in channel slope (due to a reduction in channel length), and therefore increased local velocities, shear stress, and sediment transport.
Rivers are always seeking equilibrium, so the channel will actually start to move (bank erosion / lateral shifting) to reduce that localized slope and bring things back in order.
Rivers are so fucking cool.

As someone who doesn’t know river lingo, can you translate this?

River tangled. River no like tangle. River cut off curvy bits. Connects back to make a less curvy path of least resistance.

What’s the hells an oxbow?! Are our bovine friends fashioning weaponry? Someone should tell me, do I need to buy a shield?
PapaStevesy@lemmy.world 6 months ago
Oxbow is when a flowing body of water curves out like this over time. Eventually it will redirect to the older, more direct course, leaving an arc of unflowing water called an oxbow lake. This one might have two.

Sorry, I was just quoting Mr.Weebl’s old video about the subject, probably should have linked it in my original comment XD Youtube link

I don’t know much about rivers but based on the floods we had here in Brazil early this year, I don’t think that house will be there by the end of the century.

There was no Tom Bigbee, it seems.
The name “Tombigbee” comes from Choctaw “itumbi ikbi“, which means “box maker” or “coffin maker”. There are many stories and legends about how this name came to be. One story is the river was named after a box maker who lived on some of the Tombigbee’s headwaters. Another story is based on the need for box making in the area to ship pelts during the French-dominated fur trade in the 1700’s.

Makes sense for it to be a Choctaw name, then. Isn’t the tombigby in, like, Tennessee or something?
hsdkfr734r@feddit.nl 6 months ago
I wouldn’t know. My geographical knowledge of North America isn’t good. :) Google maps points to Alabama and Mississippi, when I ask it about the river’s name.
BlackPenguins@lemmy.world 6 months ago
Reminds me of a Wild Thornberrys episode I saw when I was a kid where they fell off a boat and needed to cross a mountain to catch it on the other side.
Mango@lemmy.world 6 months ago
Is it an oxbow or a puppyhammer?

This is why setting borders based on rivers is fundamentally flawed.
This message brought to you be the latitude/longitude gang.

I mean, you say that now, but if someone stood on the other side of the river and shot arrows at you, would you really disagree with them?

Such a stupid border decision. They should have fixed it in the territory swaps a few years ago.

Why? Apart from such cases being rare, everyone gets a half island
PapaStevesy@lemmy.world 6 months ago
Because they change and move over time. This river didn’t start out like this.
I_Has_A_Hat@lemmy.world 6 months ago
The alternative is pretty fucking stupid too. Imagine losing access to your freshwater because the river shifted across an imaginary line. At least when the border is the river, you always have access to the river.
