Our videos are made with a passion for teaching river conservation science. In 2008 we produced a DVD with 60 short teaching videos for
the Missouri DNR and Missouri Department of Conservation with support from US EPA 319 funding. You can get a copy at cost here.
The NSF-funded Science Education Resource Center (SERC) also hosts a collection of our videos, and
there you can download full resolution versions. Clips have no audio unless indicated otherwise.
All videos are in QuickTime format, free download here.
- Introduction to the Emriver Em2 Geomodel.
A three-minute introduction to our Emriver Em2 river model, showing its elegant engineering, portability, ease of use, and advantages over traditional sand-filled, "home brew" stream tables. (Large file: 34 Mb, with audio) Low-resolution 12mb version here.
*Emriver straight channel simulation.
A straight channel formed in the Emriver model develops meanders. Note formation of fluvial features such as point bars and a floodplain. Video speed is 10x actual. (8 Mb)
- Emriver Em4 installtion.
Installation of our first Emriver Em4 at Winona State University in June 2008. The Em4's box is 4m long by 1.5 m wide and tilts on two independent axes. The Em4 uses our newly-developed media that is color coded by size. The yellow particles are largest with white in the middle and brown/black as the smallest sizes. (Large file: 28 Mb, with audio)
- Grand River remeandering, 1939 - 1996.
A sequence of eight aerial photos running from 1939 to 1996 show remeandering of a reach that appears as a straight, probably recently channelized reach in 1939. The location is six miles north of Grant City, Missouri. An animated blue line traces the channel changes. (2.1 Mb)
- *Emriver - Grand River remeandering comparison.
This clip opens with a flyover of the Blockton, Missouri 7.5' quad (from 1975 photography) showing the Grand River (see other clips here). We next see a flyover of a 1996 aerial, which is then contrasted with meander development in the Emriver model showing strong similaritites between the two. Frame width is about 1.1 m at top and 1.8 km for the Grand River. (2.6 Mb)
*Inchannel gravel mining and bar pit capture with audio narrative.
You'll see headcuts, incision, terrace formation and more. This clip has an audio narrative by Steve Gough. Note the download size. (18Mb)
Smaller 7mb silent version here.
Sediment-bridge interaction.
This video using our 2D flume shows how coarse sediment can alter hydraulics at a bridge crossing or culvert.This is also part of a new series of clips we are working on for the Missouri DNR and Missouri Department of Conservation with support from US EPA 319 funding. (11 Mb)
Ozark riffle fish underwater.
A short sample of one of our favorite underwater clips. Dusky shiners and a few other small fish in the Jacks Fork River in the Missouri Ozarks. These images inspire us to do our most important work - river ecosystem conservation. (10Mb)
Kate and dogs underwater.
Steve's wife Kate and two official LRRD stream habitat assessment dogs swimming in the beautiful Current River in the Ozark National Scenic Riverways in southern Missouri. (8 Mb)
*Extreme inchannel gravel mining.
Extreme inchannel gravel removal simulation showing strong headcuting and incision reponse both up and downstream. (7 Mb)
Camera housing-induced bed material movement.
Shot on the Jacks Fork River in the Missouri Ozarks. The camera housing is placed in shallow, high velocity flow, causing turbulence and changes in velocity distribution that mobilize chert bed particles. (3 Mb)
*River Dozer of Doom.
Fun with our Emriver model and a few props. Yes, Little River Research & Design can help (but we don't really have a fire truck.) This video has a great soundtrack! (18 Mb)
