A framework for assessing the health of coastal waters: Qld trial

While the assessment framework and indicators described in this report are for use by a range of stakeholders from community to state government, the report is specifically written for the NLWRA (as a final report on a project to trial the national set of 19 estuarine, coastal and marine resource condition indicators in Queensland). As such it contains information and data that is in excess of the needs of the intended users. The purpose of the indicators provided (more)...

Indicator protocols: baseflow salinity

Stream salinity is a useful indicator of catchment salinity. It may be comprised of baseflow (groundwater) and surface water components. Baseflow salinity is important because it indicates the relative contribution of groundwater salinity to total stream salinity. In more rapidly-responding local groundwater flow systems, rising baseflow salinities over time generally indicate an increasing groundwater contribution to the stream flow and, therefore rising water tables. It is also an (more)...

Indicator protocols: depth to groundwater

Rising trends in the average level of water tables may provide an early indication of an increased land salinity risk in a catchment. Similarly, falling water table levels may be an indicator of the effectiveness of mitigation strategies (Coram, Dyson & Evans 2001); it may also be a consequence of reduced recharge due to climatic factors or increased groundwater extraction from bores. Static water table depths indicate that recharge to the aquifer is equal (more)...

Water erosion hazard

Water erosion causes losses of soil that far exceed the rates of soil development and the on-site consequences affect agriculture by: decreasing soil volume available for the plant root to exploit selectively removing nutrients and organic matter breaking up paddocks into physically smaller units. Off-site effects relate to the sedimentation of creeks, rivers, estuaries and reservoirs, increased flooding, eutrophication, and the general (more)...

The Impact of Groundwater Use on Australia

Groundwater and surface water resources are often closely linked. This has particular implications for Australia and how we manage our water. As a result of this connectivity it is possible to allocate the same resource twice, to surface water users and to groundwater users. This double allocation of the same water has reduced the flow in our rivers and streams. There has never been a nationwide review of surface water and groundwater interaction in Australia and consequently the extent of (more)...
