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 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...

development in this state. Q & A agrees with Mistry that two major “push” factors that are making producers in his part of Europe look elsewhere are tough environmental laws and limited agricultural land that is costly and increasingly hard to find. “There’s no doubt that the environmental laws in northern Europe are a lot tighter than they are here,” says Van der Sluis. “It’s almost impossible...
متن کاملLivestock Development in South Dakota
Livestock producers and processors who deal in beef cattle, hogs, sheep, and poultry are also finding South Dakota to be an excellent location for processing plants and large-scale livestock operations. All this, makes for some general public concerns as residents in communities around the state try to chart a course that will allow for farm development while protecting the environment and deal...
