Research Areas

1)       Flow and transport processes in and around hydraulic structures and flow obstructions (flow and contaminant transport processes at river groynes, flow and transport processes around bridge piers and abutments, flow over river bedforms, flow through water pump intakes, study of flow disturbances and measurement errors induced by a boat-mounted Acoustic-Doppler Current Profiler ADCP in a channel)

2)       Stratified flows (study of the physics of intrusion gravity currents and bottom-propagating gravity currents over smooth flat and inclined surfaces and over surfaces containing large-scale roughness elements –ribs, dunes, cyclic steps-, interaction of gravity currents with pipes situated at or close to the bottom of the ocean, interaction of gravity currents with submerged dams, study of the ejection of a non-buoyant or buoyant miscible contaminant from a rectangular bottom-river cavity)

3)       Prediction of flow, sediment transport, and bathymetry changes in open channels with loose beds (prediction of flow, sediment transport and morphological processes in curved bends and river meanders, study of the flow physics using eddy resolving techniques)

4)       Shallow flows (shallow mixing layers and shallow wakes, study of flows at river confluences, influence of large-scale bed roughness)

5)       Eco-hydraulics (restoration of ecological habitats in rivers, fish passage studies for several hydropower dams in the Pacific Northwest, temperature stratification studies, prediction of the flow and bed shear stress distribution in river reaches for mussel population models, flow around isolated and clusters of freshwater mussels)

6)       Flow in porous media (flow in channels containing patches of vegetation and aquatic canopies, gravity currents propagating into a porous medium or in a channel containing a porous layer, air flow past porous fences and snow drift implications, flow past porous cylinders)

7)       Computational fluid dynamics (LES, hybrid RANS-LES modeling) and large-scale parallel computing

8)       Other topics: numerical simulation of floods using 1D Saint-Venant solvers, aerodynamics of golf balls, prediction of the air flow fields around rain gauges, snow fence design, prediction of wind loads on traffic signs.
