Extensive laboratory facilities and instrumentation are available at the Environmental Fluid Dynamics Laboratory, located within the 1,860 square meter Queen's University Coastal Engineering Research Laboratory.

Queen's University is ideally located on the shore of Lake Ontario. Field research is conducted throughout the Great Lakes in collaboration with the National Water Research Institute of Environment Canada. Field studies are also possible in smaller Canadian Shield lakes including the Queen's University Biological Station and Eagle Lake field site.

My research activities focus on transport and mixing processes in the aquatic environment and their impact upon water quality.  Recently, my lab has been developing process-based models to aid lake management.  This includes models and parameterizations for deep-water oxygen concentrations, turbulent mixing, sediment resuspension, harmful algae blooms and the impacts of both climate change and offshore infrastructure development on water resources. Selected research themes include:

Internal waves, turbulence and mixing in stratified flows:

Field measurements are collected and computational models are applied to investigate the circulation and mixing dynamics in lakes and coastal oceans.  Recent work has focused on developing parameterizations for turbulent diffusivity from temperature microstructure measurements and improving observation of turbulent dissipation in bottom boundary layers.

Sediment resuspension in lakes and coastal oceans:

Lab experiments and field-scale numerical models are being applied to understand how wave-generated currents resuspend sediment material in lakes and coastal oceans.

Hydrodynamic and water quality modelling in lakes:

Computer models have developed to the stage where they can be routinely applied by managers, engineering consultants and researchers for diagnostic and prognostic simulations of aquatic hydrodynamics and water quality (e.g., effects of nutrient loads on eutrophication).  My group is developing and applying computer models for management of the Great Lakes and inland waters.

Development of calibration-free Sediment Oxygen Demand models:

The Sediment Oxygen Demand (SOD) is a parameter that regulates deep water oxygen concentrations in lakes and reservoirs.  However, in computer based lake management models, the SOD is typically a constant variable that is tuned so that model results match observations.  This has no predictive value.  My group is performing high-resolution numerical simulations and analyzing field data to develop calibration-free SOD algorithms.

Undergraduate courses

CIVL 451 - Lake, Reservoir and Coastal Engineering

The fundamental hydraulic processes regulating lake hydrodynamics, reservoir operation, and coastal engineering are discussed. Topics include wave theory, wave measurement, wave record analysis, wave transformation, seiches, tides, storm surges, turbulent mixing and transport of pollutants. Student projects are assigned on computational reservoir modeling, analysis of field data and reservoir operation as well as the design of breakwaters and ocean structures and the use of hydraulic and numerical coastal models. Prerequisites: CIVL 350 or permission of the instructor.

CIVL 350 - Hydraulics II

Topics in open channel flow including friction, specific energy, free-surface profiles, culverts and hydraulic-jump energy dissipaters. Lake dynamics and environmental hydraulics will be introduced. The basic underlying concepts of water resources and hydrology will be discussed. (0/5/0/10/33)

CIVL 260 - Civil Engineering Design I

The objectives of this introductory course are: to introduce students to engineering design and the challenges and excitement of the civil engineering profession; to develop written and oral communications skills; to develop an appreciation and ability for teamwork, creativity and time/project management; to develop skills in idea generation, creative problem solving, and research; and to develop skills in using computer applications in engineering design and analysis. The course exposes students to civil engineering design through case studies and group projects. Students are expected to learn about the design process through practice and, where possible, through implementation. Design projects are team-based and as such students need to learn how to work effectively with their peers. Sketching and AutoCAD are also be introduced and used. The design principles and concepts introduced will be used in follow-on courses throughout students' degrees. (0/0/12/12/24)

Theory will be discussed with reference to field observation, computational and laboratory modelling of lake and ocean flows. Three term-hours, winter.

CIVL 855 (Subtopic) - Hydrodynamics of Lakes, Reservoris and Coastal Oceans

This introductory level graduate course covers the fundamental geophysical fluid dynamics processes occurring in lakes, reservoirs and coastal oceans. Topics include: wave theory, wave measurement, wave record analysis, wave transformation, seiches, Rossby, Kelvin and Poincare waves, Ekman dynamics, tides, storm surges, nonlinear internal waves, turbulent dissipation and mixing.
