Current research: 

Areas of research

  • Experimental environmental hydraulics: effect of ambient turbulence on turbulent jets, shallow flow mixing. Experimental investigations using laser-induced fluorescence (LIF) and particle image velocity (PIV)
  • Numerical and physical modeling of hydraulic structures mainly for hydropower
  • Habitat restoration and sediment transport and cohesive sediment erosion in rivers
  • Water resources management: sustainable water supply management
  • Potable water quality and ecotoxicology

Funding from NSERC, FQRNT, CFI, NFRF and, municipal and industrial collaboration

Environmental Hydraulics Laboratory (Director)

The laboratory has a 1.5 m x 6 m x 1 m glass towing tank. Experiments can be run in a quiescent and turbulent ambient or in a simulated flow. The approximate homogeneous turbulent ambient with no mean flow is created using a random jet array (1.5 m x 1 m). A large recirculating shallow flume 1.5 m x 9 m x 0.2 m can be used for shallow flow (river) studies. Two small shallow flumes can be used for sediment and recirculation studies. Experimental data on flow velocities and concentrations can be acquired using particle image velocimetry (PIV), acoustic Doppler velocimetry (ADV) and planar and point laser induced fluorescence (LIF) at high spatial and temporal resolution (100 渭m at 1600Hz), 3-D particle tracking velocimetry (3D PTV) at high spatial and temporal resolution. The equipment available includes a 5 W argon ion laser, a number of CCD digital cameras, a Nortec ADV and assorted optics.
