Geoscience Australia has developed a computer-generated 3D model which conceptualises the key
hydrogeological components of the Hodgson and Kings Creek sub-catchments in south-eastern
Queensland. These are headwater tributaries of the Condamine River, and are situated in the
agriculturally important Darling Downs region south-west of Toowoomba. Groundwater is an
important resource for rural communities and landholders in the area, and is used extensively for
crop irrigation, stock and domestic purposes, and town water supplies. Our principal objective in
building the 3D model was to help promote greater understanding and appreciation of the region's
groundwater resources among the numerous local people and communities that rely upon
groundwater, but who may not be familiar with the key concepts and principles which govern its
intrinsic behaviour. Additionally, the model can be applied by surface water and groundwater
scientists, water planners and natural resource managers to assist in the ongoing study, management
and administration of the region's important aquifer systems.
