Emriver modeling media

We offer two types of modeling media: Non-Color Coded and Color Coded by Size. Our modeling media is made of recycled, ground melamine plastic. It has a density of 1.6 g/cc, about 60 percent the density of quartz sand, which means it demonstrates river processes with impressive accuracy on compressed scales of space and time. The media is lightweight, easy to transport, won’t damage pumps, and is much easier to clean than sand and other quartz materials.

Color-Coded Media – “Memphis” Mix

The Memphis mix, like the Carbondale, has a range of colors and allows for easy view of sediment transport processes. This mix has finer particles sizes than the Carbondale mix and allows better demonstration of certain geologic processes such as landslides, headcuts, and dam and levee failure. It comes standard with the Em4 and can be bought as an upgrade to the Em2 and Em3 models.

Average particle sizes:
Yellow: 1.02 mm
White: 0.62 mm
Black: 0.33 mm
Red: 0.14 mm

Color-Coded Media – “Carbondale” Mix

Our original mix in use since 2008 has a range of colors and allows for easy view of sediment transport processes. We are currently only offering this mix to clients who need refills of their current stock.

Average particle sizes:
Yellow: 1.4 mm
White: 1.0 mm
Black: 0.7 mm
Red: 0.4 mm

Non-Color-Coded Media
“Alpha” Mix

Non-color-coded Emriver modeling media comes standard with the Em2 and Em3 models. Media particle sizes are between 0.4 mm and 2.0 mm.
