Senior Surface Water Modeller

• Aug 2011 - Dec 2012

I was employed by Golder Associates Africa in the Water Resources division where I have focussed my efforts on developing dynamic water balance models in GoldSim for various mining clients. Current and completed projects include the following: - Dynamic water balance for Two Rivers Platinum Mine. - Water balance models for Anglo American Thermal Coal (10 coal mines). - Dynamic water balance for Iduapriem Goldmine, Ghana. - Dynamic water balance for Liqhobong Diamond Mine, Lesotho. - Surface water management plan for Mooifontein Uranium Mine. - Dynamic water balance for Venetia Diamond Mine. - Pit dewatering model for Lumwana Copper Mine, Zambia. - Stormwater management for post closure landforms at BHP Energy Coal, South Africa. - KOSH Regional Water Management Scheme. - Kriel and Matla Regional Water Treatment Plant. - Charlie 1 stormwater management plan for Sasol, Secunda.

Manager, Geosciences Group, R&D

• Jul 2001 - Jul 2011

I was a member of the Environmental Science & Technology research division in the corporate Research and Development function. I was the manager of the Geosciences Research Group. The focus of this group was on Geochemistry and Geohydrological aspects of the water and waste systems associated with the largest coal mining and coal to liquids processing complex in the world at Secunda.

Senior Environmental Scientist

• Jan 1999 - Jun 2001

I worked as a Senior Environmental Scientist (Consultant) focussing on water quality management in the mining environment. A large portion of the work involved hydrological and chemical modelling of the impact of mining and related activities on the surface water environment (see item 5 in the publication list). The following activities were included in my duties: - Research into passive treatment technologies for acid mine drainage. - Mine closure planning and costing. - Storm water planning and management. - Development of GIS databases for various mines and industries. - Water and salt balance modelling. - Pipe system and reactor design. - Evaluation of hydraulic characteristics of reactors using tracer methods. - Research into the hydraulic behaviour of various complex organic materials.

Research Scientist

• Jan 1997 - Dec 1998

This was a full-time (2 year contract) research position in the Department of Chemical Engineering, sponsored by the Water Research Commission. The main focus was research on disinfection of treated sewage effluent but a limited amount of teaching assistance was included in my duties.
