Abstract
Geological and soils mapping and an assessment of groundwater conditions has been carried out to assist development planning in the new town of Tuggeranong, in the Australian Capital Territory. The rocks of the area are mainly volcanic rhyodacites and the depth of weathering is generally less than 15 m. Residual soils are mainly podzolic clays; transported soils range from partly cemented gravelly, sandy silts (slope- wash) to complex layered clays (alluvium). Foundation conditions are generally expected to be satisfactory in most areas for single-storey structures, and large buildings are expected to be founded within 5-10 m of the surface in the town centre area. Excavation conditions will be variable because of the irregular weathering profiles characteristic for the volcanic rocks. Groundwater occurs in fractured rock, colluvial, and alluvial aquifers, and could be used for irrigation in places. Groundwater seepage problems are associated with the pediplain basins, and some remedial drainage works are necessary. Sand deposits in the bed of the Murrumbidgee River constitute a major resource but supplies of rock aggregate will have to come from outside the area. The location of sanitary landfill sites will require detailed study to evaluate the risk of surface water and groundwater pollution.
