Emriver models are ideal for teaching about river and coastal dynamics in geology, hydrology, sedimentology and geomorphology. By scaling down time and space, the interactive models allow students to understand processes that most often occur too slowly to observe in the field.

Emriver models have been integrated into the instruction in geoscience courses such as the following: engineering geology, environmental geology, physical geology, fluvial geomorphology, hydrogeology, hydrology, and sedimentology.

Beispielthemen und Lektionen

• How rivers form, erosion, deposition, channel migration, point bars, cut banks, meander cut-offs, erosional terracing, delta development, headcuts, sediment transport, continuity, channel stability
• Impact of riparian buffers, floodplains, various approaches to bank stabilization and armoring
• How development and infrastructure should be informed by a knowledge of river and coastal dynamics
• Planetary surface processes
• Imaging with photogrammetry and LiDar
• Coastal and estuarine morphology (with use of Wave Maker)

Example Applications in Geosciences

• Stream Table Lab for Environmental Geology 101 and follow-up lab
• Planetenforschung; Oberflächenprozesse auf dem Mars
• Lab: Introduction to applied fluvial geomorphology in stream ecology using the Emriver Em2. Teaching concepts include sediment transport process, continuity, river long profiles, adjustment to disturbance, influence on fish habitat.
