Field estimates of groundwater discharge – Great Artesian Basin, South Australia
Understanding the water balance of large groundwater systems is fundamental for the sustainable management of the resource. However, measuring many of the major components of the water balance pose considerable challenges and are thus estimated through modelling. A shortcoming of the modelling approach is that the water balance may have high bias and uncertainty due to insufficient information....
متن کاملQuantifying near-surface, diffuse groundwater discharge along the south-west margin of the Great Artesian Basin
Few field measurements are available to constrain the diffuse discharge (or vertical leakage) component of the water balance of the Great Artesian Basin (GAB), even though numerical modelling indicates that it accounts for over half of the outflow of the GAB in South Australia. High leakage rates are observed along the southwestern margin of the GAB where the aquifer is close to the surface wit...
متن کاملMolecular phylogeny and biogeography of spring-associated hydrobiid snails of the Great Artesian Basin, Australia.
The Great Artesian Basin (GAB) of Australia underlies some of the driest parts of South Australia and Queensland and feeds numerous freshwater springs. Prominent and endangered components of the GAB spring community are snails of the family Hydrobiidae. This paper examines the evolutionary relationships of the entire hydrobiid fauna associated with the GAB, and includes appropriate non-GAB spec...
متن کاملDesert Springs of the Australian Great Artesian Basin
The Great Artesian Basin (GAB) underlies about one fifth of mainland Australia. Much of this area is arid or semiarid and often artesian water is the only reliable source of potable water, historically via springs. Prior to the 1870s, there were around 3,000 flowing springs ringing the GAB. The springs were a vital source of water for Aborigines as well as early explorers, workers and pastorali...
متن کاملFramework for incorporating spectral observations into steady state analysis of groundwater discharge around the margins of the Great Artesian Basin
Diffuse groundwater discharge (also known as vertical leakage) forms an important and poorly constrained component of the water balance of the Great Artesian Basin (GAB), Australia’s largest groundwater resource. Around the south-western margin of the GAB, the diffuse leakage from the artesian aquifer discharges into the unconfined water table and subsequently into the atmosphere via evapotrans...
