Unravelling the Mysteries of Groundwater Systems for the Australian Public - Improved Hydrogeological Visualisation and Understanding with Computer-Generated 3D Models

摘要

The Australian community needs better understanding and appreciation of groundwater. This knowledge will significantly assist in the sustainable extraction and use of our national groundwater resources, both now and into the future. 3-dimensional (3D) computer-generated models have the potential to impart this general awareness and bring the basic principles of hydrogeology to diverse public audiences. 3D models are vibrant and exciting; we can make good use of their 'wow-factor'and generate enthusiasm for otherwise esoteric topics which lack mainstream recognition. Importantly, each model can be tailored for individual user groups and their groundwater systems, with locally significant issues given particular focus. This educational approach has successfully been applied for two headwater sub-catchments of the Condamine River, situated near Toowoomba in south-eastern Queensland. Armed with an interactive hydrostratigraphic 3D model of the Hodgson and Kings Creek district, we successfully delivered wide-ranging groundwater information to key stakeholders and the general community. Captivated by novel subterranean views and lively question-and-answer sessions, our audiences gained significant insight into important hydrogeological concepts such as aquifer heterogeneity and the multi-dimensional architecture of their groundwater systems. This knowledge can subsequently be put to practical use by groundwater users, and help to guide best-practice groundwater extraction, management and administration. Without this targeted and innovative approach it is difficult to envisage how such information could be conveyed as easily or as rapidly to the local community. Potential uses for 3D conceptual groundwater modelling are undoubtedly considerable and with many specific scientific applications, yet their suitability as tools for general public education should never be overlooked.
