EmFlume1.5
EmFlume1.5
A compact (1.5m) and versatile flume for teaching open-channel hydraulics and sediment transport. The 1.5-meter channel, coupled with easy control over slope, flow and depth, allows students to learn the qualitative and quantitative methods for understanding and characterizing flow. The inclusion of the color-coded media provides for quick demonstrations of bedload transport phenomena such as dune migration and scour around structures.

Stilling Tank
Stilling Tank
The Stilling Tank helps diffuse turbulence before water enters the hydraulic channel.
Magnetic Flow Meter
Magnetic Flow Meter
The in-line magnetic flow meter has no moving parts and provides accurate discharge measurement in L/m. It will also display the water temperature.
Pump Controller
Pump Controller
The Abyzz A100 Pump Controller inputs steady speed range (0 – 100%) to the sine-wave controlled, three-phase synchronous pump.
Hydraulic Channel
Hydraulic Channel
The ultra-scratch-resistant acrylic Hydraulic Channel measures 1.52m x 93mm x 204mm (59.8″ x 3.7″ x 8″), and tilts vertically for transport and storage.
Tilt Mechanism
Tilt Mechanism
Flume slope is adjustable between -0.6˚ to 5.7˚ (-1.0% to 10%) through a smooth acme jack mechanism.
DIgital Inclinometer

The EmFlume1.5 is a versatile tool for demonstrating open channel hydraulics to students of civil engineering, environmental fluid mechanics, fluvial geomorphology, sedimentology and stratigraphy. The compact and user-friendly design allows instructors and students to set up experiments and visualize outcomes quickly. It is easy to transition from working with sediment to working with a clean channel, and variables such as flow and slope are altered with simple controls. The EmFlume1.5 comes with a variety of tools and inserts (see spec sheet), which facilitate the demonstration of many phenomena, and provide students an intuitive, experiential understanding of hydraulics.
Demonstrations and labs include:
- Reynolds number
- Velocity profiles
- Froude number and specific energy curve
- Manning’s equation and roughness coefficients
- Hydraulic jump
- Conservation of specific energy with sluice gate
- Calculation of discharge using weirs of various profiles
- Inlet and outlet control in culverts
- Incipient motion of sediment
- Ripple and dune development and migration
- Pier scour
- Coastal morphology (with addition of Wave Generator)
The EmFlume1.5 features a silent, variable-speed DC pump, a magnetic flow meter and a digital inclinometer. The flow meter can be turned off, allowing students to calculate discharge using appropriate formulas before powering it back on to verify results.
When not in use, or when moving to another lab, the hydraulic channel can be tilted into a vertical position so the entire system fits within the footprint of the cart. Ample room in the cabinet allows for the storage of all the hydraulic inserts and sediment.
