7.5 Modelling A digital model of the basin is needed to allow better prediction of the effects of siting new bores, and manage extraction in varying climatic conditions. Such a model should incorporate salt transport to try to improve understanding and management of the salinity problems. 7.6 Bore Construction The method of constructing large diameter bores is successful, but bore performance is little better than properly screened 150 mm bores. In view of the high-cost of large diameter bores it is recommended that 150 mm screened bores, stabilised with gravel-packs and carefully developed should be used. 7.7 Salinisation The weathered metamorphic rocks around the fringe of the Town Basin contain highly saline water, usually at relatively shallow depth. Problems are already evident in Golf Course and some other parts of the town. Care should be taken with future subdivisions that recharge is not increased, and that over irrigation is avoided. 65
