Emriver em4

A robust, modular geomorphological research system capable of simulating floodplains, deltas, groundwater processes, and sediment transport.


Em4 specifications
Dimensions 3.7 m x 1.2 m (12 ft x 3.9 ft)
Portability Moveable, but not easily portable
Water 265 L (70 gal)
Media Amount 163 kg (360 lb)
Media Type Color-coded
Base Options Static, single, and dual-tilt
System Also Includes Reservoirs, pump, power supply, flow controller. Modeling accessories: measuring tape, quartz and plastic stones and rocks, acrylic shapes to simulate culverts, plastic vegetation, dye injection bottles for visualizing flow, scoops, and scrapers. User and laboratory manual, river geomorphology DVD.

UPGRADES – Modular options that can be added at any time.

  • Tilting Base
    -Upgrade to single-axis or dual-axis tilt base to simulate river processes on a greater variety of landscapes and to demonstrate the effects of groundwater flow on land formations and sediment behavior.
    – Single tilt allows modification of the slope. Dual tilt allows modification of the slope and roll.
    – Tilting is controlled by hand cranks.
  • Accessories
  • Research instruments
