Glossary of terms

adaptive management system
a dynamic management approach responsive to changes in knowledge, resource condition and trend, and/or changing management priorities
part of a geological formation or group of formations containing sufficient saturated material to transmit and yield significant quantities of water to bores or springs
artesian aquifer
an aquifer where beds above and below the aquifer are impervious and where the water is confined under pressure, so that the water level in bores penetrating the aquifer will rise above the top of the aquifer and reach ground level. These bores become flowing bores.
artesian bore (also flowing bore)
a bore where water rises up the bore column to a point above the land surface
artificial outflows
includes flows from all bores accessing Basin aquifers (flowing or pumped)
in the context of bore maintenance, a guarantee or certainty that water infrastructure is maintained after the payment of a fee or premium against loss or failure
benefit (public and private)
investments in on"“ground works across the Basin will lead to a range of benefits. Private benefits are those enjoyed by a private individual or body corporate, while public benefits are those enjoyed by all or in the public interest.
assemblage of different species of plants and animals
biodiversity outcomes
biological consequences of specific actions
bore column
bore lining used to stabilise the drill hole and to seal off undesirable material
bore drains
small earth channels used to distribute water from an artesian bore to other parts of a pastoral property
capital investments
investments made in water infrastructure to produce a product
ceased-to-flow bore
a bore which was once artesian but, due to the fallen aquifer pressure, the water level in the bore no longer rises to land surface
consumptive use
water used for a purpose (for example, living plants, animals, irrigated crops, manufacturing and mining) not returned directly to groundwater storage
controllable bore
a bore with headworks and a control valve installed and where that device is in working order
controlled bore
a bore that has been rehabilitated and has a control valve installed to control discharge or a bore that has a control valve installed during construction. The valves may or may not be in working order.
duty of care
Common Law duty of care applies to everyone who may harm another as a consequence of their actions. Duty of care applies to harm that may be caused to both: (a) those who are living at present; and (b) those who are not yet born. In a natural resources context, it relates to the need to not impact on natural resources when damage could have been foreseen.
ecosystem health
state and functionality of ecological processes within an ecosystem normally expressed in terms of one or more indicators
authority issued under a particular legislative system representing the share of the water resource issued to the holder
environmental flows
water required to maintain ecological processes within an ecosystem which may be temporally, spatially and volumetrically variable
extractive flows
water discharged through a bore either under its own pressure or by a pump
groundwater-dependent ecosystems
biological systems dependent on groundwater for existence. Includes ecosystems dependent on mound springs, springs and soaks
energy stored in a water mass, produced by elevation, pressure or velocity
head reversal
where the water level falls below ground level or some previous level at an earlier time
structure including various valves installed at ground level and attached to the top of the bore column used to control discharge from artesian bores
higher value uses
uses of groundwater which derive the best economic value
infrastructure renewal
rehabilitation or replacement of bore headworks and casing, and replacement of bore drains with piping networks and troughs
in-kind contributions
non"“financial contributions
institutional arrangements
measures, practices established under law, guidelines or principles by a government agency
institutional failure
failure by a government agency or institution in its role, responsibilities or policy implementation
institutional reform
reform or review of processes and practices used by a government agency or institution to carry out its responsibilities
intake beds
areas where an aquifer intercepts or is close to the ground surface and where surface water or rainfall can move from the surface to the aquifer
Integrated Resource Management
management approach considering, in the decision-making process, interdependencies among land, water and vegetation variables
investment (public and private)
public investment is a financial outlay by government (public monies). Private investment is a financial outlay by individuals or privately owned corporate bodies.
management zones
management tool to differentiate between different areas of the Basin with different hydrogeological and bioregional attributes and issues
market failure
when the market does not constrain the allocation or use of resources to a level that maximises social, environmental and economic benefits. It results when an economic factor is ignored or overlooked and so remains without a price or value.
measure of volume, being one million litres or one thousand cubic metres
monitoring network
a network of bores used to measure the pressure, water levels or water quality of an aquifer
mound spring
geomorphic formations raised above the surrounding land surface formed by a deposit of minerals and sediment brought up from artesian aquifers or confining beds by water at certain natural discharge points in the Basin. Mound springs are generally confined to the south-western corner of the Basin. Note: Other spring systems not raised above the surrounding land surface occur throughout the Basin. See also groundwater-dependent ecosystems.
National Water Reform Framework
a wide-ranging framework for reform of the water industry endorsed by the Council of Australian Governments (COAG)
an association of persons, companies, organisations or government agencies that share the risks and benefits from the association or alliance based on clear objectives and responsibilities
priority environmental and cultural heritage assets
groundwater-dependent and water-remote ecosystems and cultural heritage features identified and generally agreed to be of sufficient value to warrant their protection and management ahead of other competing values
open land where rainfall is too low for agricultural cropping or improved pasture and where livestock graze on native pastures
reactivated bores
bores which recommence flowing from pressure increases due to infrastructure renewal
process where groundwater is replenished, usually by infiltration of surface water or rainfall entering an aquifer; also occurs by water intentionally added to an aquifer, usually via a bore or excavation that exposes the aquifer
recharge rate
rate or volume per unit time at which water is recharged to an aquifer
recharge zones
see intake beds
regulatory and statutory instruments
instruments made under an Act, another statutory instrument, or a power conferred by an Act or statutory instrument and also under power conferred otherwise by law. Examples of statutory instruments include a regulation, an order-in-council, a rule or a guideline of a public nature.
regulatory framework
applicable legislation and regulatory and statutory instruments
rehabilitation of a bore
relining of existing bore with new casing and replacement of bore headworks
reticulation systems
system of bore drains or pipes which may cross one or more properties to distribute water across the landscape
shared investment
where two or more parties invest financially or inkind to achieve a mutually beneficial outcome
social capital
characteristics of social organisation such as networks, norms and social trust, or bonds which help coordination and cooperation for mutual benefit. Evidence suggests cohesiveness in societies is crucial for societies to prosper economically and for sustainable development. It measures the ability to deal with challenge or change.
stock water demand
volume of water required by stock at a property scale. May be calculated in reference to a specific time period, such as an hour, day or year
subartesian bore
a bore in an aquifer where the water does not rise above the ground surface and does not flow. Water must be pumped to the surface. Note: In some parts of the Basin the term "non-flowing artesian bore" is used in preference to "subartesian bore". In these instances "subartesian" refers only to bores in non-artesian aquifers.

water use efficiency
a comparative figure, generally the fraction of total discharge used to produce benefits. Calculated as the ratio of consumptive use to total discharge or the value or extent of production per water unit consumed assessed against a nominated standard or norm. For example, efficiency of water use from a bore is the volume of water consumed by stock divided by the total bore discharge.
watering points
troughs, tanks, or other structures used to provide water. Includes bore drains
