Tim is a chartered professional engineer with 13 years of experience in water engineering.  He has worked on a wide range of river, water, wastewater, stormwater, flooding, mining, water resources and coastal engineering projects. He has published numerous journal and conference papers on both research and engineering applications.

Tim has a particular expertise in environmental hydraulics, which is the application of hydraulic engineering to environmental problems, such as water quality, sediment and erosion and aquatic habitats. Recent examples of projects include design and construction of a 1.4km stream diversion for Solid Energy, which included aquatic habitat features as well as flood conveyance. Another major project has been the design and construction of stormwater treatment devices for the 7.5 km ALPURTB2 northern motorway extension. Tim also has experience using sophisticated numerical models to simulate the environmental effects of coastal, such as 2D modelling of the Westport port expansion in Malaysia and 3D modelling of canal developments in NZ.

Tim graduated with a BE(Civil) and ME(Civil) for research into plume dispersion from University of Canterbury. His PhD from University of British Columbia, Canada, was for research into the environmental hydraulics of lakes and outfalls, as applied to the treatment and disposal of mine wastewater. Tim has worked in New Zealand, Malaysia, Canada and the UK. He has been responsible for the development of engineering projects, including feasibility, consents, design and implementation.
