We offer two types of modeling media: Non Color-Coded and Color-Coded by Size. This media is made of recycled, ground melamine plastic and is about 60 percent the density of quartz sand (1.6 g/cc). This means the media can demonstrate river processes with impressive accuracy at the space and time scales of our river models. The media is lightweight, easy to transport, won’t damage pumps, and is much easier to clean than sand and other quartz materials.
Sediment transport processes are easily viewed with the range of colors and sizes in the color-coded mixes. This media comes standard with the Em4 and can be bought as an upgrade to the Em2 and Em3 models. We will help you decide what size mix is best for your needs. An example of average particles 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.
We can help you determine how much of our media you would need to fill your own stream table. Please contact us with the dimensions of your table.
