Foundation testing for a building project at Robe aimed at strengthening the existing slipway has shown the presence of medium strength Bridgewater Formation limestone at a depth of less than 2 m, which should provide an adequate bearing horizon for...

A new town water supply well, Naracoorte no. 10, encountered permeable confined aquifer sands at 160 m depth. Subsequent testing showed the well to have a yield of from 6000 to 7000 cubic m/day at a recommended pump intake depth of 85 m, with less...

Hydrogeological investigations undertaken by SADME at the Lock Coalfield have shown that significant aquifer systems occur above and beneath the coal, and that the coal itself has negligible permeability. Permeability of both aquifers is low,...

A well survey was carried out in the Naracoorte Township and immediate environs in May and June 1976. 128 wells were located in the surveyed area, two thirds of these being in use, and of these, 11 were for drainage disposal. The remaining one third...

Shallow drilling (<30 metres) at 14 sites intersected a regressive coastal sequence of Quaternary bioclastic sediments deposited in coastal aeolian, littoral, lagoonal and evaporative-lagoonal environments. Major calcrete carapaces assist the...

Flint occurs in 4 geological settings in the South-East - beds and dykes in the Gambier Limestone, bouldery conglomerate of the Bridgewater Formation, Holocene surface lag deposits and Holocene beach deposits. Pebbles from beach deposits between Cape...

Eighteen rotary drillholes with bottom-hole core and one diamond drillhole were completed northwest of Port Lincoln and intersected quartzite, schist, calcsilicate, graphitic schist and marble attributed to the Hutchison Group. These drillholes were...

The Blue Lake is a valued water resource for the City of Mt Gambier and there is increasing community concern regarding its longer term sustainable use. The lake is groundwater fed and there is known contamination of the unconfined aquifer in the...

The groundwater resources of the Tertiary sand aquifer in the County Musgrave Proclaimed Wells Area (PWA) have been reviewed in order to assess the potential for their use to augment groundwater currently extracted from the unconfined Quaternary...

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....

In the main irrigation area of the Padthaway Proclaimed Wells Area, viticulture is the dominant form of agriculture, and has been since the early 1970s. Local groundwater, extracted from the underlying Quaternary unconfined aquifer, is used...

The main source of irrigation water in the intensely irrigated area of the Padthaway Proclaimed Wells Area is groundwater extracted from the underlying unconfined aquifer. Excess irrigation water, that is, water applied to the crops but not used,...

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 Robe-Naracoorte coastal plain provides a unique record of Quaternary sea level changes through the preservation of a large number of shoreline sequences corresponding to repetitive sea level high-stands. This record has resulted from a combination...

Human and animal footprints are preserved in 2 different settings near Clare Bay. Macropod tracks occur in laminated beach sediment of Late Pleistocene age (c. 110 000 year BP). They are preserved beneath a former prograding coastal fore-dune complex...

Sedimentation in the Great Australian Bight (GAB) has occurred in a variety of settings from the initial intra-cratonic rift to the modern carbonate shelf. An extensive palaeodrainage system, remnants of which are still preserved, supplied clastic...

The Groundwater (Border Agreement) Act of 1985 legislated to provide a framework for the joint management of groundwater resources within a 40 km wide strip along the length of the South Australian and Victorian Border, which is referred to as the...

Several groundwater issues have been highlighted in the Meningie-Narrung area as a result of the regional investigation into the hydrogeology of the Murray Basin. Dryland salinity is the most important, with an estimated 45 000 ha to be affected by...

The Nundroo basement drilling project was proposed in February 1987 by SADME's Regional Geology Branch as the first phase of investigation of the little known rocks of the south-western Gawler Craton. Previous drilling in this area had been restricted...
