Small water storage usually managed by the landowner with a capacity usually less than 100 ML. The volume includes dead storage.

This definition applies to:

A part of the physical environment with properties that can be observed; these include natural features such as rivers, aquifers and the atmosphere, and human defined or constructed features such as channels, irrigation districts and urban supply areas.

This definition applies to:

Homogeneous collections of common features, each having the same spatial representation, such as points, lines, or polygons, and a common set of attribute columns, for example, a line feature class for representing road centrelines. The four most commonly used feature classes in the geodatabase are points, lines, polygons, and annotation (the geodatabase name for map text).

This definition applies to:

Soils with high free iron and clay contents. They occur along the eastern coastline, in northern parts of Western Australia and the Top End.

This definition applies to:

Containing iron and typically having reddish-brown colour.

This definition applies to:

A period used for reporting of annual financial statements in Government and other organisations. In Australia this usually refers to the 12 months starting 1 July and ending on 30 June.

This definition applies to:

The first quartile of a set of numbers is the value in which 25% of the numbers are below it and 75% of the numbers are above it when the numbers are arranged in ascending (increasing) order.

Synonym: 25% quartile

This definition applies to:

Flooding occurring within about six hours of rain, usually the result of intense local rain and characterised by rapid rises in water-levels.

This definition applies to:

An advice of the potential occurrence of flooding inferred from forecast meteorological considerations and an assessment of catchment wetness. The issuing of a flood watch is meant to indicate that vigilance to potential flooding is required of the community.
