Rivers case studies

 


The Pioneer River

For many years, DSITIA, formerly DERM has used the Integrated Quantity and Quality Model (IQQM), a hydrologic (surface water) model with limited representation of groundwater processes. In August 2011, the Department began a project to develop, calibrate and compare two parallel hydrologic models for the Pioneer River system, in Source IMS and IQQM.

The River Murray

eWater CRC is working in partnership with some of Australia’s key river management agencies to develop the next generation of river system operations tool. The Murray-Darling Basin Authority (MDBA) is trialling the operational mode of Source to support operation decisions in the River Murray System. The aim of the trial is to improve water management and delivery for agriculture, communities and the riverine environment in the southern Murray-Darling Basin.

The Namoi River

The groundwater module in Source can determine the exchange flux between a river and the underlying aquifer for each link and at any time step. The Namoi - specifically the Gunnedah to Narrabri reach - is the main river system for testing this groundwater module in the planning mode of Source.

The results of the trial have been very promising. They clearly indicate that Source can take explicit account of the influence of groundwater processes - a first for any river model. This has the effect of removing groundwater exchange processes from the category of unaccounted losses and ungauged residual inflows. Moreover, this functionality explicitly accounts for the time lags associated with groundwater processes and therefore enhances the forecasting capability of river models.

The Goulburn River

From Lake Eildon downstream, the floodplains of the highly regulated Goulburn River have experienced a significant reduction in overbank flow events, which are important for floodplain health. Because of this, the Goulburn-Broken CMA are using Source to explore their options around restoring a greater frequency of these events.

As releases of environmental water from Lake Eildon require large volumes of water, the Goulburn-Broken CMA are using Source to explore the options around augmenting tributary inflows.

The Macintyre Brook

In conjunction with the Queensland Department of Science, Information Technology, Innovation and the Arts(DSITIA), eWater is trialling the planning component of Source in the Macintyre Brook system. The focus of this testing is applying Source to the modelling of a river system with a continuous sharing water resource assessment and allocation system. The aim is to improve water management, resource assessment and delivery in the Macintyre Brook system.
