Drill cores from six holes drilled by the South Australian Engineering and Water Supply Department at the site of the proposed Little Para Dam Water Treatment Works were logged, paying particular attention to core loss, rock defects and intensity of...

15 auger holes which were drilled to a maximum depth of 10 m have shown a gently dipping sequence of Quaternary silt and clay, passing down at about 6 m depth into a dense Tertiary sandstone. The highly calcareous, plastic silt which occurs...

The Northern Power Station, presently under construction, is the third power station to be built at Port Augusta. Two previous stations (Playford A and B) were constructed during the 1950s, although investigations into the feasibility of using the...

Diamond drilling and geophysical logging of 5 holes into the dam wall has shown the concrete to be significantly decayed in places. Geological mapping was also undertaken in the area adjoining the spillway.

Describes 2 areas of instability at Hallett Cove Railway Station and on Greenhill Road.

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...

For the past 30 years or more, much of the town water supply for Orroroo has come from wells that are completed in the confined aquifer of the Walloway Basin. The unconsolidated, fine, silty sands of this aquifer become mobile and have led to a...

The County Musgrave Proclaimed Wells Area on Eyre Peninsula, situated mainly near Elliston and extending eastwards towards Lock, contains a number of small groundwater lenses of potable quality which are surrounded by brackish to saline groundwater....

An initial investigation was undertaken by The Department of Primary Industries and Resources SA (PIRSA), into the increase in salinity within wells on the Northern Adelaide Plains (NAP). This involved interpreting groundwater salinity data from a...

Metropolitan Adelaide is founded on a wide variety of soils that overlie sediments and rocks. Some of the soils and sediments react to seasonal and human-induced changes in water content with marked changes in volume. The black earths and...

A fundamental question remains to be answered in the Clare Valley. How much water can be safely extracted without causing depletion of the groundwater resources? This question is being addressed by a major investigation into the groundwater...

Phase Two of a drilling program at Clare, South Australia was undertaken in June, 1997. A total of 6 bores were drilled, 4 of these at existing locations established during Phase One drilling in January, 1996, and a further 2 at Watervale Oval as...

Groundwater held within fractured rock aquifers has been shown to be obtainable from a number of vastly different geological settings, including indurated sediments, low to high-grade metamorphics, acidic and basic volcanics, and intrusive igneous...

Detailed lineament analysis of the Cooper Basin area has established the presence of two lineament networks. A gas-prone network of NW and NE trending lineaments shows strong correlation with the presence of gas in alternating blocks, but no gas...

Cambro-Ordovician Warburton Basin strata and intrusive granites are conventionally regarded as the economic basement beneath the Cooper-Eromanga oil and gas province in northeastern South Australia and southwestern Queensland. This study, the first...

A preliminary study was made of the near vertical coastal cliffs adjacent to Gordon and Stock Street, Aldinga. Continued landsliding of soil-strength cliff-forming materials and toe erosion by the sea have threatened the clifftop esplanade roadway,...

Ground conditions to be expected during construction of the proposed Myponga Water Filtration Plant were determined for the EWS Dept. Twenty two backhoe pits were logged and 800 metres of seismic refraction profiling was carried out. Both the site of...

Holdfasts were installed at Morialta Conservation Park to improve safety for rock climbers. Twenty three rockbolts were grouted into holes drilled into rocks of the Stonyfell Quartzite Formation. Two rockbolts were grouted into cast concrete blocks...
