| Research Interests |
| Environmental Fluid Dynamics |
Turbulence and mixing in natural flows such as in the atmosphere, rivers, estuaries, and ocean.
Recent research projects include :
- Odour dispersion from landfill sites
- Coastal water quality modelling
- Wind, wave and current interactions at the port entrance
- Turbulence structure and mixing at gas-liquid interfaces
- Near-shore sediment dynamics
- Structure & mixing efficiency of stably stratified turbulence
- Bio-hydrodynamics of estuaries

| Projects |
| Odour Dispersion from Landfills |
Summary: |
Investigating odour trails from municipal solid waste landfilling operations. The Bisasar Rd landfill site was used as a case study for the development of a comprehensive odour management system. The system is based on real-time weather monitoring, advanced air dispersion modelling, and receptor feedback.
Graduate Student : Mr Guy Laister (graduated Cum Laude)
MSc Thesis (2002) : "Prediction, management, and control of odour from landfill sites"
Graduate Student : Mr Duncan Roebuck (graduated Cum Laude)
MSc Thesis (2005) : "Odour management at Landfills"
Funding : Durban Solid Waste |
| Wind, waves & cross-currents |
Summary: |
The effects of adverse weather conditions on shipping operations in the port entrance channel. Innovative digital imaging techniques were developed for tracking ships in the port entrance channel and for deducing the cross-currents that the ship experiences.
Graduate Student : Mr Sahil Patel
MSc Thesis (2002) : "Application of digital imaging in measuring cross track drift of vessels entering a port"
Funding : Department of Transport ; National Port Authority |
| Coastal water quality |
Summary: |
Investigating the effects of urban runoff on beach water quality. Development of simple models for predicting pathogenic pollution of the beaches. For more info and to check current beach pollution status, visit our coastal water quality web site
Graduate Student : Mr David Mardon (graduated Cum Laude)
MSc Thesis (2003) : "Coastal Water Quality"
Funding : National Innovation Fund (DEAT) |
