We offer two different types of modeling media: Non-Color-Coded (see information below) and Color-Coded-by-Size, which shows sediment transport and deposition according to size.
Our modeling media is made of recycled, ground melamine plastic (learn more on Wikipedia). It has a density of 1.6, about 60% 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 and easy to transport. It won’t damage pumps, and it is much easier to clean than sand and other quartz materials. 1 cubic foot of media is 50 pounds (1 liter of media is 1.76 pounds).
Media particle sizes are between 0.4 mm and 2.0 mm.
