An underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt).  May be confined between layers (for example clay) or unconfined.  Reference :


 Vertical hole drilled into the ground to access the groundwater / water table.

Data Loggers

Electronic device which records measurements electronically over time.  In groundwater investigations, they can be fully submersible, and when calibrated with barometric loggers (which measure the atmosphere pressure), these devices can indicate the height of the standing water level in the groundwater / aquifer.


Digital Elevation model.
A 3 dimensional computer graphical representation of the earths surface. Reference :

The Department of Sustainability and Environment was a state government department that managed water resources, climate change, bushfires, public land, forests and eco systems in the state of Victoria, Australia. The DSE is now under the branch name The Department of Environment, Land, Water and Planning (DEWLP) found at

Water held underground in the soil, in pores and/or crevices in rock


Rock layers containing or  related to groundwater


The Ability of computer systems or software to exchange and make use of information.  i.e. 'interoperability between devices made by different maufacturers'


Physical characteristics in relation to rock or rock types


Data (Information) that provides information about other data. 3 types exist : descriptive (identifies a resource i.e. title, abstract, author etc), structural (describes how pages form chapters etc) and administrative (who, when and how a file was created).  reference :

Open Geospatial Consortium (OGC)

The  Open Geospatial Consortium (OGC) is an international not for profit organization committed to making quality open standards for the global geospatial community. These standards are made through a consensus process and are freely available for anyone to use to improve sharing of the world's geospatial data. Reference :


The amount of salt (ionic compounds, not necessarily 'table salt' or sodium chloride) found within water. The 'saltiness' of water.


Spatial information is the digital connection between location, people and activities. This information can graphically (use picture representation) illustrate what is happening (where, how and why) to show the insight and impact of the past, the present and the (likely) future.  The knowledge produced by spatial information is fundamental to the lives of every Australian and New Zealander.  It ends with a map.

Telemetered Data 

An automated communications process by which measurements etc are collected at remote sites and transmitted to receiving equipment for monitoring. Reference :


University of Ballarat.  Now known as Federation University. For more information:

Water table

An unconfined aquifer(body of water) which is  below the ground surface. Lakes, rivers etc. are examples of the water table is visible.
