Evaluation and Management of Groundwater System

Specialises in the modelling of groundwater flow and contaminant transport through environmental systems using one-, two-, or three-dimensional geological, conceptual and mathematical models implemented in a computer model. Geological systems include porous and fractured media under saturated or variable saturated (vadose zone) conditions, while analytical, semi-analytical or numerical techniques are used for the implementation of conceptual and mathematical models in computer codes.

  • Hydrogeological Data Analysis and Interpretation
  • Development of Numerical Groundwater Models
  • Development of Process Level groundwater flow models (fully/partially or unsaturated flow) for:
    • Mine dewatering/re-watering for dredge mines, open cast and underground mines;
    • Water supply to mines, towns and cities and farming communities;
    • Groundwater impact assessments (input for EIA);
    • Input into geotechnical slope stability models;
    • Research studies;
