Mass wasting and other slope processes using Emriver plastic sand. from Steve Gough on Vimeo.
At LRRD we have notebooks full of "what ifs" for our models. As I worked on other things last weekend I put together this little demonstration and checked one off the list.
The video speaks for itself. I've always known our plastic media could be used to demonstrate hillslope processes, but this is the first time I've attempted to record it.
I'm a fluvial guy and not so well versed on slope stability outside of the situations I see in stream banks — and even those are usually handled by a geotechnical engineer on my team.
So I'd appreciate comments on this little demonstration and how we can improve and expand it.
I was surprised to see how well the "mudflow" demo worked, especially since my wetting method was very crude. With slow, methodical saturation of the slope, I think we could make wonderful simulations of this process.
We will likely have some interns working here this summer, and this looks like a great project for one!
As noted in the video, the flickering you see is from one of the awesome skylights we installed — great for energy savings, but not too hot for time lapse lighting on a partly cloudy day!
