Fractured rock aquifers underlie approximately 40% of the Australian continent, including the Murray–Darling Basin, and many of Australia’s mining and CSG
regions, including the Pilbara and the Surat Basin. Fractured rock groundwater systems test the limits of hydrogeology as it is practiced today. Site characterisation in fractured rock aquifer studies is an inherently multiple-scaled effort, where characterising fractured rock systems is the creation, development, testing, and refinement of the conceptual hydrogeologic model.
WHY IS THIS COURSE IMPORTANT?
Groundwater flow and transport processes in fractured rock aquifers are fundamentally different to in porous media (sedimentary) aquifers. Aquifer systems in which flow is controlled predominantly by fractures include indurated sediments, metamorphic and igneous rocks. Hydraulic conductivity in these systems is often controlled by the distribution and aperture of fractures. Groundwater flow occurs predominantly through fractures, whereas the rock matrix acts as a storage reservoir. The methods taught at university apply mainly to porous media aquifers, and many people do not realise that they need to use different methods when investigating fractured rock systems. This course covers the best methods for investigating groundwater flow and contaminant transport in fractured rocks. It is the first opportunity the Australian groundwater community has had for training in this area
WHO SHOULD ATTEND?
Practicing hydrogeologists, consultants, hydrologists, engineers and students in government, industry and academia should strongly consider attending.
WHO IS PRESENTING?
- Dr Fred Paillet has spent the majority of his career running the US Geological Survey’s research program in the geophysical characterisation of aquifers. He also works with Golder Associates in Brisbane and with University of Queensland Civil Engineering on mine drainage problems.
- Dr Andy Love has over 20 years experience as a principal hydrogeologist with the SA government and is currently Senior Research Fellow in Hydrogeology at Flinders University and the NCGRT. He has collaborated internationally in his study of geochemical and environmental tracer techniques.
- Doug Weatherill is a consultant hydrogeologist with Sinclair Knight Merz in Australia. He has specialist skills in groundwater flow and solute transport modelling, applied tracer testing and fractured rock hydrogeology.
