Em4串流表
Em4串流表
A robust, modular geomorphological research system capable of simulating floodplains, deltas, groundwater processes, and sediment transport. The Emriver Em4 is the largest moveable bed stream table available on the market, and well suited for colleges and universities with ongoing research and teaching in river and coastal science.

The Em4 comes standard with the K500 Digital Flow Controller.
Single-Tilt Base
Single-Tilt Base
The Em4 comes standard with static supports but the vast majority of users elect a single or dual-axis tilting base.
Standpipe

Model Footprint: 4.22 m x 1.27 m (166 in x 50 in)
The scale of the Em4 allows for long-term experiments that develop mature river systems with parallel channels, multiple meanders, cut-offs, oxbows and islands, and has space for a large pool to build impressive deltas. With the addition of a Wave Maker, the Em4 can be used to model coastal morphological phenomena such as longshore drift, estuaries, barrier islands, and tombolos. The very large size of the Em4 allows a whole class of 25 plus a teacher or facilitator to participate, with a second row of 20 observers.
The Em4 stream table is as much a research tool as it is a teaching tool, and can be found in laboratories at major universities around the world as well as at research institutes and museums.
The two reservoirs hold a total of 70 gallons of water, so the lab should ideally have a dedicated spigot and floor drain. There is a drain valve built into the upstream reservoir so the system may be quickly emptied. The standard static supports are engineered from high-strength aluminum and create a box slope of 3 degrees, but the vast majority of our clients opt for a single or dual-tilt base.
The Em4 comes standard with 360 pounds of our color-coded by size thermoset plastic modeling media, and also comes standard with our K500 digital flow controller in addition to the standard K28 flow controller. The K500 allows precise, metered control of water flow using an Omega paddle wheel flow meter with closed-loop monitoring and adjustment. The K500 displays measured and requested flow in milliliters per second, total water volume since startup, and elapsed run time. It also includes eight preprogrammed hydrographs to model common flood sequences.
