  IAH NSW Technical Talk – February 2026

  Numerical Groundwater Flow Modelling in Australia: Applications, Case Studies & Practical Pathways. Please Australia’s varied hydrogeological settings demand groundwater models that are defensible, fit-for-purpose and aligned with the Australian Groundwater Modelling Guidelines. This talk outlines a practical workflow for developing appropriate models using different MODFLOW codes and software, supported by PEST calibration and uncertainty analysis. Case studies from mining, landfill, infrastructure and remediation show how numerical models support inflow estimation, closure recovery, leachate level simulation, saline intrusion assessment and permeable reactive barrier design. The presentation highlights transparent communication of assumptions and uncertainty, demonstrating how well-designed models guide impact assessment, engineering decisions and long-term water management across Australian conditions.
  
  Speakers' bio:
  Tingting is a hydrogeologist and numerical modeller with 15 years’ experience across mining, infrastructure/tunnels, landfill and contaminated land in Australia and New Zealand. She specialises in conceptual model design; MODFLOW USG/NWT and MODFLOW SURFACT for complex/density dependent cases; FEFLOW; PEST assisted calibration; and MODPATH/mod PATH3DU particle tracking. Her work focuses on impact assessment, tunnel and shaft inflows, mine closure recovery, leachate head control and hydraulic containment optimisation. Tingting holds a Master of Engineering in Groundwater Management (UTS, 2007) and serves on the IAH NSW committee.
