Hydrology and hydrogeology for water supply, mines and dams

We assess surface water and groundwater for water supply, mining, dams and hydropower, from single farm boreholes to whole catchments.

Typical questions include how much a borehole will yield, whether a pit needs dewatering, and how seepage from a tailings facility could affect groundwater. We answer them with field testing and numerical modelling.

ACapabilities

What we do

  • Water resource assessments

    Surface and groundwater availability for farms, towns, industry and mines, with sustainable abstraction estimates.

  • Pumping tests

    Design, supervision and analysis of step and constant-rate tests to establish borehole yield and aquifer properties.

  • Hydrogeological investigations

    Aquifer characterisation, borehole siting, water level and quality monitoring, and mine dewatering assessments.

  • Surface and groundwater modelling

    Numerical models of catchments and aquifers for abstraction, dewatering and contamination scenarios.

  • Hydro-forecasting

    Seasonal to sub-seasonal streamflow forecasts to support hydropower generation planning and water allocation.

  • Permeability testing for dams

    Lugeon (packer) testing of foundation rock to guide grouting and seepage control.
