General information

Professor Gaskin joined McGill in 1997, adding to the environmental engineering expertise in the Department. Environmental hydraulics and water resources is her specialty. Her teaching includes open channel flow, hydraulics, river engineering and water sustainability. Her research is in the general area of environmental fluid mechanics and water resources management. Specifically looking at topics in experimental fluid mechanics: modeling of jets and plumes, river engineering, sediment transport in surface waters, and in water resources management: sustainable water supply management and basin wide hydrologic modeling.

Research interests

Environmental hydraulics laboratory (Director)

Environmental Hydraulics Laboratory
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). 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 μm at 1600Hz). The equipment available includes a 5 W argon ion laser, a number of CCD digital cameras, a Nortec ADV and assorted optics.
