You are invited to contribute to the review of Australia's guidelines for the use of Acoustic Doppler technology in streamflow measurement.

It's been more than four years since the National Industry Guidelines for hydrometric monitoring were published by the Bureau. To keep pace with changes in technology and practice, they're now due for review.

Rainfall conditions 1 July 2015 to 30 June 2016
Annual rainfall conditions 2015–16

The Bureau’s Water in Australia 2015–16 report shows that reserves in storages declined by seven per cent during the 2015–16 year. Despite annual rainfall being near average, it fell at the wrong time of year in many areas so reserves were drawn down.

Of the water that makes it into our rivers, how much goes to the landscape, how much goes to the atmosphere, how much is extracted for consumptive use and how much flows out to sea?

The Australian Water Resources Assessment River (AWRA-R) model makes it possible to quantify this for river reaches and whole river systems—taking into account river inflows, current river volume, losses to groundwater, overbank flooding and return flows, and rainfall and evaporation at the river surface.

Groundwater Dependent Ecosystems Atlas showing aquatic groundwater-dependent ecosystems around Australia

The Groundwater Dependent Ecosystems Atlas (GDE Atlas) now includes new regional-scale mapping for parts of New South Wales, Northern Territory, Queensland, South Australia and Victoria.
 
The web application also has a fresh look with new functionality including powerful searches and new contextual map layers such as groundwater management areas.

While our seasonal streamflow forecasts are better now than they were five years ago, or even two years ago—whenever we ask users how we could improve, a common response is ‘provide forecasts with greater accuracy and reliability’.
 
Increased forecast performance will allow water managers to more confidently make planning and operational decisions.

To continually improve the forecasts, we have developed a long-term collaboration with the University of Adelaide and the University of Newcastle.
