Our unique modeling media provides remarkable visualization of sediment transport processes and enhances research in sedimentology and stratigraphy. The 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 behavior and channel morphology 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 stream table sand and other quartz materials. We offer two types of media: Non Color-Coded and Color-Coded by Size. Color-coding allows for visualization of sediment transport and deposition according to grain size. From advanced sedimentology research to K-12 education, our modeling media is a powerful tool to have.

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 Emriver modeling media, also known as the "Alpha Mix" comes standard with the Em2 and Em3 models and does an excellent job at showing sediment transport processes. Media particle sizes are between 0.4 mm and 2.0 mm.
If you are looking to convert from stream table sand, 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.
