Grid-based gravity, ground magnetic and EM depth sounding surveys were conducted in the Coondambo area in the search for Olympic Dam style mineralisation possibly associated with regional gravity highs. The licensee failed to attract a joint venturer...

Detailed follow-up to earlier regional stream sediment sampling, which had disclosed several robust kimberlitic garnet indicator anomalies in relatively featureless terrain, was successful in discovering three outcropping thin kimberlite sills in the...

A study tour of water resource planning, development and management in Israel, France and United States has shown the need for geologists involved in groundwater hydrology to familiarize themselves with aquifer modelling and computer techniques. At...

A computer model was based initially on a previous report. Following the setting up of the physical dimensions of the model, hydrologic parameters were applied. A number of runs of the model were made incorporating changes until the model represented...

Summarises all work from 1.7.78 to 1.7.82, including bibliography of all hydrogeology and engineering geology reports for Eyre Peninsula and the Far West.

Study of artificial recharge to reduce desalination costs and extend the life of existing or proposed well fields included microcomputer modelling of the operation of Aroona Reservoir under various recharge systems and simulation of the effect of...

The effects of pumping from the main aquifer for 20 years at 900 L/sec from hypothetical well 125 km north of Marree, have been simulated using the GABHYD computer program of the BMR. Results indicate that effects outside SA will be minimal and that...

The Departments method for estimating and reporting gas reserves has been revised to include estimates of tight gas as well as providing more accurate estimates of conventionally recoverable gas reserves. This has included a new method for...

As part of the South Australian Exploration Initiative, the use of high resolution aeromagnetic and radiometric surveying in petroleum exploration was tested in Block B5 west of Moomba. A number of associated studies were undertaken to utilise the...

Computer modelling of magnetic anomalies from the South Australian Exploration Initiative aerial magnetic surveys of the Cooper Basin in April 1993 was undertaken with the following objectives: - use measured susceptibilities to calculate theoretical...

A regional groundwater model has been constructed of the Loxton Sands watertable aquifer in the eastern Riverland, over an area extending eastwards from Overland Corner to the State border. It is being used to quantify the salt load impacts on the...

Aquifer storage and recovery (ASR) is being developed as a solution to provide an emergency town water supply in a location where blue- green algae make River Murray water unfit for domestic use during summer. Algae-free river water will be injected...

Recently imposed water resource management controls in the Angas - Bremer Irrigation Area have reduced the local irrigators' aggregate groundwater allocation to within the sustainable limits of the basin, primarily by conversion of their licences...

An aquifer storage and recovery scheme is being developed at Clayton township on Lake Alexandrina, South Australia, notably as a solution to provide a town water supply in a location where blue-green algae make River Murray water (extracted via the...

Trial dewatering of the quarry, which is excavated in fractured and well-bedded Cambrian dolomite, took place for at least 56 days during early 1994, but pumping was terminated when a further significant water level drawdown could not be achieved. Ten...

The groundwater model described in this report was used to quantify the changes in salt loads to the River Murray and induced discharge to the degraded river flats of proposed future management options for the Loxton Irrigation Area. The options...

The Torrens Rural Catchment can be divided into three zones where groundwater extraction from fractured rock aquifers is significant - the Fourth and Sixth Creek catchments, and the Birdwood - Gumeracha area. The Fourth Creek Catchment, which is...

An increase in groundwater salinity in parts of the Padthaway area threatens the sustainability of established irrigation developments. A number of management options to mitigate the groundwater salinity increase are being considered by State...

The United States Geological Survey software package MODFLOW was used to construct a three-layer predictive simulation model of the groundwater flow underlying Emu Springs, an area in the southern Mallee region of South Australia near Tintinara. The...

A combined groundwater and solute transport model (MODFLOW and MT3D) was constructed of the Loxton Irrigation Area to determine the future impacts on groundwater levels and salt loads to the river and floodplain for a range of local irrigation...
