We have used the Emriver Em3 fluvial geomodel to demonstrate a variety of processes and resulting morphologies to undergraduate students. We’ve demonstrated different channel types, channel migration, point bar development and cut banks, meander cut-offs, erosional terracing, knickpoint migration, channel incision, delta development, the effects of base level on the depocenter, and delta-lobe switching. Overall, this geomodel has been a very useful educational tool to provide a visual example for some basic concepts of fluvial and deltaic geomorphology.
