You'll find information about the person who conducted this experiment in the video description at right. But it looks as though sand only (?) was used for the experiment.
I did not conduct this experiment. I was given permission to upload it to my channel by Dr. Paul Heller from the Univ/Wyoming. You can download the video yourself from his website. Link at right --->
Good thinking on your part, though: Sediment size is always an important scaling consideration in any flume experiment.
The flow process is good. A frequent occurrence of avulsions. If the inclination is higher I guess entrainment may take place more frequently than avulsions.
Hey, thank you for hypothesizing. This isn't my video. It's from a researcher in Minnesota. On what do you base your hypothesis concerning slope and entrainment?
Avulsion may be considered as a type of deposition. This is enhanced by gentle slope inclination. Entrainment is just the reverse. Higher inclination promote that. Correct me if I am wrong. Thanks.
Your explanation sounds like a plausible scenario. I have several texts on fluvial geomorphology and sedimentation, but I've never digested them to the depth that I would like to have done. Thank you for the discussion. Are you a researcher?
These are not "effects", as it were. This video depicts sedimentary events in a flume. They are completely natural events. The events are nothing more than sediment being moved by flowing water.
Stream channel avulsions are, quite simply, a change in channel direction. Frequently this occurs when a channel overtops its banks, which may be due to a slug of sediment becoming wedged in the site of the channel avulsion.
Channel expansion means exactly what it says: The expansion of channel dimensions due to increased flow.
Wow. Hello Elaina. Never expected to find a comment from YOU on a science video! Thank you for chiming in. THe processes that you see on display in this video operate along the mountain fronts of southern California whenever we have a big storm. Of course, the sediments that wash out of our canyons used to range freely across the mountain fronts; before the streams were channelized.
I don't appear interested in science - I'm gonna have to think about that, Bruce. My mother-in-law is an hydrologist - she works for the corps of engineers and LOVES her job.
Wow. Your mother-in-law is a hydroogist? Fantastic! I was a teaching assistant for the hydrology course at UCLA a few years back. Can she get me job? *LOL* Teaching doesn't pay anything!
Hey Doc. This is a long-after reply to your comment here, which I've just (re?)discovered.
Yes, I have been to the Driftless Area. My Uncle Jake was once mayor of a small town east of LaCrosse, WI and I visited there back in the 1970s when I was just a sprout. At the time I didn't know Jack Willy about the Driftless Area, but I guess I sure was in it. Uncle Jake took us all through "the coolies". Great memories.
beautiful braided result! Amazing!

hey bapyou, i was wondering what kind of sediment this person used on their experiment? how large was it? how did he get it?

Yes I am. An interesting area of research. Yet, too much observation but too much precise measurement to support existing postulations...

Nice vid.. These experiments help-us to understand more about dynamics of sedimentation...

Thanks for this video. Could you explain to me the difference between avulsion and expansion?

This was really interesting, Bruce... Thanks, too, for the additional info in your description - it helped me see the scale of what I was seeing 8‹D

The government doesn't pay well either - LOL But I bet you could get a job - she works in Sacramento - have you tried to get a job with them???

Thank you Elaina. I'll look into it. I like living in LA though. Been here 12 years.
