The Bureau now forecasts likely streamflows for the next seven days at more than 100 locations across Australia.
Our new 7-day streamflow forecasts service combines rainfall and streamflow observations with rainfall forecasts to indicate whether rivers are likely to rise or fall in the coming week. It shows whether forecast rain is sufficient to increase flow in the rivers, and how this compares to the normal flow for this time of the year.

Screen shot from Monthly Water Update showing rainfall and streamflow observations side-by-side.
Rainfall and streamflow are intrinsically linked, and the Bureau’s new Monthly Water Update will provide you with a quick overview of the recent status of both.
Each month the Update provides a snapshot of streamflows for the past month. Rainfall is a key driver of streamflow and is shown alongside flows from over 220 gauging stations across Australia’s topographic drainage divisions.

Correlation between major floods, East Coast Lows (ECLs) and Tropical Interactions.
Over the past 150 years, most major flooding along Australia’s east coast has been caused by just two types of weather systems—East Coast Lows and Tropical Interactions.
Bureau researchers have investigated more than 250 severe floods and 550 major storms for a 1500 kilometre coastal strip—from Brisbane, through Newcastle and Sydney, to Eden in southeastern New South Wales—between 1860 and 2012.

The Water Information Research and Development Alliance (WIRADA) 2014–15 annual report details the outcomes of a $5 million dollar investment by the Bureau of Meteorology and CSIRO. The Alliance delivered 11 journal papers, 27 conference papers and 21 technical reports in 2014–15, for research in water informatics, water resource assessment modelling and streamflow forecasting.

We’ve just released version 3 Geofabric data for the Pilbara–Gascoyne drainage division. Based on improved scales of mapped features and the 1 second digital elevation model (DEM), Geofabric version 3 provides users with greatly improved catchment areas that better reflect the reality of regional catchment boundaries. Version 3 also provides improved resolution and increased numbers of mapped features including rivers, lakes, water tanks and dams.
