High discharge flume

Research facility highlights

The NRC's 10 m × 2.7 m × 1.4 m deep (33 ft × 9 ft × 4.5 ft) High Discharge Flume (HDF) is used to simulate a wide range of open channel flows and study problems in rivers, canals and other inland waterways. Studies in this facility typically focus on the interaction of currents and high-speed flows with a wide range of coastal and offshore structures. The HDF can also be equipped with a drop gate structure used to simulate the dynamic effects of dam breaks or tsunami waves.

What we offer

The facility is 10 m × 2.7 m × 1.4 m deep (33 ft × 9 ft × 4.5 ft) and is made of stainless steel. The flume provides a steady flow in an open channel with continuously adjustable discharge from 0 to 1.7 m3/s (0 to 60 cfs). The discharge is controlled by a variable pitch pump, and the water level can be controlled by an adjustable sluice gate located near the downstream exit.

The flume can be partitioned as required to provide a narrower working area with increased water velocities. Models can be constructed within the flume to replicate rivers, canals, dams, spillways, etc. The flow can also be diverted into the 30 m by 50 m Large Area Basin, located directly adjacent to the HDF, where larger test channels, river models, dams or other hydraulic structures can be constructed and tested.

Why work with us
