This definition applies to:

Water backed-up or retarded in its course as compared with its normal or natural condition of flow.

This definition applies to:

Land not covered by vegetation that does not fall into any other land use/cover category. It includes eroded areas and construction sites.

This definition applies to:

The component of streamflow supplied by groundwater discharge.

This definition applies to:

A tract of country, generally larger catchment areas, drained by a river and its tributaries.

This definition applies to:

A subsurface porous and permeable layer present in a basin. A basin is a concave or syncline-like bedrock structure filled or partially filled with sediments.

This definition applies to:

Refers to methods in probability or statistics, e.g. Bayesian Joint Probability, named after Thomas Bayes (c. 1702-61), who provided the first mathematical treatment of Bayesian inference.

Related: Bayesian total error analysis (BATEA)

This definition applies to:

A modelling system that uses statistical methods to produce predictions of seasonal streamflows. BJP was developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). See the Seasonal Streamflow Forecast Research papers section for more information.

This definition applies to:

A generalised Bayesian framework for environmental model calibration and validation. BATEA permits the use of explicit probabilistic error models which are used to describe the uncertainty associated with observed data, notably, in forcing inputs and outputs, e.g. rainfall and discharge data.

This definition applies to:

The distance from the transducers of an ADCP in which no measurement is taken. Also known as the “blank”.

This definition applies to:

The typical depiction of a river or stream in a cartographic product.

This definition applies to:

A hole drilled in the ground, a well or any other excavation used to access groundwater. May be used for observation of groundwater (including water level, pressure or water quality).

This definition applies to:

Point feature class that represents the location of a bore and associated attributes. Multiple independently screened bore pipes are regarded as separate bore features.

This definition applies to:

A three dimensional line feature class that represents the hydrogeologic units along a borehole.

This definition applies to:

A table with rock or sediment types classified into hydrogeologic units along a borehole.

Synonym: hydrostratigraphy log

This definition applies to:

An independently screened inlet to a bore that can be pumped or monitored separately. A bore can have multiple pipes, each having one or more screens.

Alt text

This definition applies to:

The construction component of a bore that allows groundwater to enter e.g. casing with slots or holes.

This definition applies to:

Acoustic method used to measure boat speed and direction by computing the Doppler shift of sound reflected from the stream bed relative to the ADCP.

This definition applies to:

Farms or industries engaged in the production of grains, oilseeds and other crops (especially wheat, barley, peas, sorghum, maize, hemp, safflower and sunflower), or the grazing of livestock for meat or wool, on a large scale.

This definition applies to:

bottom tracking

Acoustic method used to measure boat speed and direction by computing the Doppler shift of sound reflected from the stream bed relative to the ADCP.

This definition applies to:

The volume of water diverted from streams and storages (surface water) or extracted from bores (groundwater) by water providers for various uses.

This definition applies to:

A water access entitlement allowing an infrastructure operator to access, take and hold water for the supply of water to another person.

This definition applies to:

The aggregation of individual rights into a single right. These might include but are not limited to: land property title, water access entitlement, water allocations, water use rights, delivery rights, irrigation rights and works approvals.
