RESEARCH INTERESTS:
My general interests are in the fields of hydraulics, water resources and environmental fluid mechanics. In particular, modelling of surface, sub-surface and closed conduit flows: unsteady friction in conduits; turbulence modelling of fast transients; flow stability; numerical modelling of surface and closed conduit flows; water quality modelling; parameter estimation; inverse analysis and water quality; modelling of island wake flows.
