Abstract

Three springs clusters are located approximately 20km north-east of Injune, in the north-eastern margin of the Surat Basin (Fig. 1). These are:
• The 'Lucky Last Springs' cluster (#230) with vents 287 and 340;
• The 'Springrock Creek' cluster (#561) with vent 285;
• The 'Abyss Springs' cluster (#592) with vents 285a, 285b and 286.
The geological setting in the realm of these springs is complex, including a number of faults (marked in black in Figure 1) which may act as a preferential flow conduits and/or hydrogeological barrier to groundwater.
This report summarizes an innovative modelling effort which aims to enhance the hydrogeological understanding of this area, with an emphasis on the springs flow mechanisms. The model was developed using FEFLOW platform due to its advance capabilities for (1) allows an unstructured grid, which increased flexibility around key areas of interest and larger cell sizes away for focus areas, (2) allows multi-level water tables, i.e., two or more phreatic aquifers, and (3) surface-subsurface interconnection.
