Great Artesian Basin - Wikipedia, the free encyclopedia The basin is the largest and deepest artesian basin in the world. The basin is 3000 metres (10,000 ft) deep in places and has been estimated to contain between 9 and 65 cubic kilometres (7 to 52 billion acre-feet) of groundwater. The basin is an important source of water for cattle raising. en.wikipedia.org /wiki/Great_Artesian_Basin   (496 words)

Tas Walker's Biblical Geology - Application to GAB Together with some associated peripheral basins it covers a significant portion of the Australian continent and is, indeed, the largest artesian basin of its kind in the world. Artesian water is held under pressure in porous sandstone aquifers capped by impervious shale beds. At the edges of the basin, and to the east of centre where the strata have been pushed up, it can be seen that the stratigraphy is eroded to form the present land surface. www.biblicalgeology.net /model/gab.html   (1894 words)

Artesian Spa -- Recommendations and Resources   (Site not responding. Last check: 2007-10-26) An artesian aquifer is a confined aquifer whose water is pressurized. Artesian wells are named after the former province of Artois in France, where the first one was drilled by Carthusian monks in 1126. The Great Artesian Basin provides the only reliable source of water through much of inland Australia and is the largest artesian basin in the world. www.becomingapediatrician.com /health/7/artesian-spa.html   (713 words)

Artesian aquifer - Wikipedia, the free encyclopedia An artesian aquifer is a confined aquifer containing groundwater that will flow upwards out of a well without the need for pumping. In recharging aquifers, this happens because the water table at its recharge zone is at a higher elevation than the head of the well. Artesian wells were named after the former province of Artois in France, where many artesian wells were drilled by Carthusian monks since 1126 (see also en.wikipedia.org /wiki/Artesian_aquifer   (240 words)

The Great Artesian Basin The Basin covers a total area of over 1 711 000 square km and it has an estimated total water storage of 64 900 million megalitres (a megalitre is one million litres and is equivalent to about half the water in an Olympic swimming pool). The Great Artesian Basin was formed between 100 and 250 million years ago and consists of alternating layers of waterbearing (permeable) sandstone aquifers and non-waterbearing (impermeable) siltstones and mudstones. Dating of the artesian waters has given ages of almost 2 million years for the oldest waters, which occur in the south-western area of the Basin. www.nrm.qld.gov.au /water/gab   (484 words)

Australia's Artesian Basin - $14 Billion down the drain each year - On Line Opinion - 15/8/1999 The traditional view of the Great Artesian Basin, which is the basis of government policies and which is taught in schools, is that the aquifer is a porous rock where the water content is continuously replenished by slow seepage from the strata outcrops in the uplands to the east. The present interpretation is based on the assumption that the Jurassic sandstones are porous, and that the porosity is unchanged by the discharge of water from the basin, or by the drop in water pressure. It may be an estimate of all of the captive water in all of the saturated sandstones, which is something radically different to the potentially recoverable water in the joints and fissures in the aquifers. www.onlineopinion.com.au /view.asp?article=993   (2682 words)

The community of native species dependent on natural discharge of groundwater from the Great Artesian Basin Excessive extraction of artesian groundwater from the Great Artesian Basin (GAB) has led to both the extinction of springs and a reduction in water flow of many of the remaining springs. Therefore, the decline in artesian water pressure and the resultant degradation and extinction of spring communities means that The community of native species dependent on natural discharge of groundwater from the Great Artesian Basin is eligible for listing as Vulnerable under this criterion. It is hoped that the better management of artesian bores will increase the pressure of the artesian groundwater, removing one of the key threats to the survival of the artesian springs. www.deh.gov.au /biodiversity/threatened/communities/gabsprings.html   (1031 words)

Capping and Piping Artesian Bores In New South Wales, the discovery of the Great Artesian Basin (GAB) in the late 19th century led to the construction of many artesian bores and the provision of assured water supplies of acceptable salinity on several stock routes previously classed as unreliable. The Great Artesian Basin, is recognised as one of the world’s largest underground water reservoirs, and is estimated to hold 8,700 million megalitres or 17,000 times the volume of Sydney Harbour. Artesian bores will be rehabilitated and wasteful bore drains will be replaced with efficient piped systems so that water can be controlled and used only when and where required. www.pipa.com.au /docs/GAB.html   (1468 words)

New funds for Artesian Basin recovery - Senator Ian Macdonald Senator Macdonald said rehabilitation of the Basin was a cooperative effort, with States, the Northern Territory and landholders heavily involved in recovery work. The Great Artesian Basin catchment is estimated to gross around $2 billion through agriculture to the nation's economy. Included in the Australian Government's commitment of $42.7 million for Artesian Basin recovery, the Government is contributing $1.35 million over two years for the completion of Western Australia's Carnarvon Artesian Basin recovery program. www.mffc.gov.au /releases/2004/04082m.html   (344 words)

Earthbeat - 16/09/00: Managing the flow from the Great Artesian Basin The Great Artesian Basin is one of the largest underground water resources in the world. But the ancient water in the Basin is undervalued; 880 bores are uncapped and they continuously gush water through 34,000 kilometres of open bore drains. But also as the pressure falls and the natural flows from the Basin, which are the springs, many of them have dried up, about half of them, and some of the others flow less, and that impacts on the natural biodiversity around the springs. www.abc.net.au /rn/science/earth/stories/s183006.htm   (1122 words)

Ancient Mound Springs Under Threat Excessive development of the Great Artesian Basin over the past century by European activity has seen an overall decline in the flows from the mound springs, and recent development of the water supply borefields for the WMC Olympic Dam Operations copper-uranium mine in the midst of the most important spring groups has exacerbated this problem. The Olympic Dam mine now uses more than 15 million litres of water per day from the Great Artesian Basin (GAB) to process the ore. The GAB is a vast and ancient body of water that lies deep under the surface of central Australia.

Great Artesian Basin recovering pressure One of Australia's great outback icons - the Great Artesian Basin - is recovering after years of falling pressure. Speaking at a meeting of the Basin Coordinating Committee in Longreach, Australian Conservation Minister Senator Ian Macdonald said substantial progress had been made thanks to the dedication of landholders, with some financial help from government.

Technology in Australia 1788-1988, Chapter 3, page 168 9) in the late 19th century led to the construction of many artesian bores and the provision of assured water supplies of acceptable salinity on several stock routes previously classed as unreliable. Accelerated mining of artesian supplies and consequent reduction of pressure and lowering groundwater levels led to a realization that this source was not unlimited. Extensive investigations, aimed at establishing the extent of the Great Artesian Basin, its safe yield and the characteristics of its waters, were set in train by Nimmo and others and a reasonable understanding of this unique water resource was available by 1930. www.austehc.unimelb.edu.au /tia/168.html   (314 words)

AgForce criticises Artesian Basin water plan AgForce says the Queensland Government's draft water resources plan for the Great Artesian Basin (GAB) is not based on sound science. The Department of Natural Resources released the draft plan in February designed to manage resources for the largest underground water storage in Australia. A spokesman for Natural Resources Minister Henry Palaszczuk says AgForce has already been granted an extension to reply to the draft water resource plan and claims by it that the plan has been rushed through are unfounded. www.abc.net.au /news/items/200512/1526668.htm?westqld   (196 words)
