This definition applies to:
- feature
-
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:
- feature class
-
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:
- first quartile
-

Synonym: 25% quartile
This definition applies to:
- flash flooding
-
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:
- flood threat advice
-
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.
