Mine Surface Water Management Assessment
Project Highlights
Integrated Sustainability developed a calibrated numerical groundwater model to characterize contact water migration beneath spoil areas and pit lakes over a 100-year period. Simulations included arrival times and flow rates to surface receptors, supported by a sensitivity analysis and interception well scenarios.
Project Deliverables
- Developed a 3D numerical groundwater model simulating flow from spoil zones and pit lakes over operational, closure, and post-closure phases.
- Estimated seepage rates to surface water features.
- Calculated long-term arrival times for contact water to reach surface receptors, highlighting spatial variation and areas of early emergence.
- Completed sensitivity analysis on porosity.
- Modelled groundwater interception wells. Identified recommended monitoring well locations based on transmissivity, groundwater gradients, and modelled flow paths.
