Our first Em2(x) model ships!

Our first Em2(x) model ships!

After many months of research and design we shipped our first redesigned Emriver Em2 (which we call the Em2x at the lab). We’re in full production mode, all the kinks are out and we’re building models.  And have a lot of orders to fill (thanks!)...

A strong first in experimental fluvial geomorphology.

I’m happy to report we’ve made high quality 3D measurements of channel form in our Em4 model using close range photogrammetry (CRP) in Ana Londono’s lab at the Dept. of Earth and Atmospheric Sciences at St. Louis University. Working with one of our...

Modeling media research–the fine color coded fraction.

Modeling media research–the fine color coded fraction.

We’re continuing our research on low density modeling media.  The mix we usually use tapers out at around 0.5mm on the fine end, but clearly adding smaller particles has a big effect on behavior in movable bed models.  This fraction fills the interstitial spaces...
