Stream table time lapse with meander cutoff and headcutting
At 1:02 the first meander cutoff occurs with extensive headcutting afterward as the channel tries to lower its gradient. The headcutting is visible as an advancing white line. At 1:39 I excavate halfway thru the area of the next meander cutoff, which finally occurs at 2:18. Tremendous amounts of sediment are eroded/transported after each meander cutoff. This 3 min video represents 90 min of real time. The hybrid sand (mixture of white plastic sand and dark mineral sand) makes erosion, transport, and deposition easier to see.

This river simulator consists of a plastic tray 3.5' l, 1.5' w, and .5' deep filled with approx 100 lbs of hybrid sand (2 parts plastic sand to 3 parts mineral sand) with a fountain pump in a 5 gal bucket reservoir to recirculate the water at about 30 ml/s. The plastic sand has a density roughly half that of the mineral sand. It is must easier to erode, is mostly white in color and moves much f...
Science experiment ruined stop fucking touching it you dumb bitch
Amazing
It doesn't make any difference until humans start living in the area and building stuff along the banks, and then in the river itself. Then we get worried and upset at what's happening to our stuff.
This is weirdly satisfying..
Why didnt you leave the delta to form
This reminds me of a pair of gloves I used to have. I lost them on the subway. They were made of pig skin with rabbit fur lining. Before I lost them, I punched a pumpkin...my fist went right in! Please make more memories...I am running out.
Are you ok?
@@joachimmacdonald2702 Yeah but did I tell you I like eggs?
The phobic lift neurobiologically kiss because korean weekly melt modulo a four frail puffin. grotesque, weary grandmother
youtube loves these hydrology videos now
on god
I know of a narrow river bend close to where I live that broke through just like 0:58. The way the stream's new bend erodes makes me think the river will erode into the road.
this reminds me of that one episode in avatar where they just absolutely destroy a fire nation machine with nothing but a single drop of water.
which episode?

shouldnt have touched it and remade the banks with the eroded sand
How to do the oxbow lake.
stop touching it!
Shutup
exactly my thoughts xD like wtf
Interesting
Very boring but helpful to understand and even I did it
1:00 An oxbow lake forms
That was actually kind of soothing. Might make me one of them stream tables.
For anyone using this video for the "Stream Table Experiment" lab I believe that the 5-minute mark is at 00:15 and the 37-minute mark is at about 01:11 Please correct me if I am wrong!!

Very interesting! Well done!
wtf he created meanders with hand then its not a realistic situation anymore
I ACTUALLY THINK ITS PRETTY COOL THOUGH.
MORE WATER ! FASTER TIME LAPSE! $$$$$$$$
This is made much less interesting by the repeated interference and changes made by someone's hands. Get it started and keep your hands off. Helping it do what you think it should do takes away what it could teach by doing its own thing.
that was the hand of God coming down......
He actually had to interfere because the sand moves down stream and builds up. He doesn’t want sand getting into the pump.
@@themelancholyofdude959 I think just putting it at the head of the creek would have been better just because of the simulation of water from upstream coming downstream, also fixes the problem of there being no more material for the water to erode.
If you want to see it actually form MAKE ONE YOURSELF IF YOU DONT LIKE THIS ONE
did the amount of water flowing through the system remain constant throughout this experiment?
For realism it shouldn't, as river volumes change seasonally
I'd like to do something similar in my classroom. Where do you buy the plastic sand?
I don’t think he’s gonna answer
yes is
