Water allocation to River Murray wetlands: a basin-wide modeling approach

The primary aim of this project was to relate the water regime preferences of wetland plants to hydrology throughout the Murray River Basin and to predict the volume of additional water required to achieve optimal plant species diversity. This report details the methods and key findings of the project which examined the impact of regulation and changes in water allocation on the community composition of wetland plants through the Murray River basin. Due to a lack of primary data, it deals (more)...

Scoping Study: Improving plants' water use efficiency and potential impacts from soil structure change - research investment opp

The key questions addressed by this scoping study are:

• What understanding, techniques and tools require further explanation or development to improve water use efficiency?
• How well do we understand the impacts of long-term irrigation on soil structure? What are the effects of soil structure change (within and around the root zone on the flow of water and rate of movement along various pathways of salts?

Investigation improvement to irrigation drainage systems

The Goulburn Broken Catchment Management Authority identified irrigation drainage as contributing 47% (1999) of the total catchment phosphorus loads to the Murray River each year. Environment Protection Authority guidelines for managing environmental impacts of construction projects, in this case the mobilisation and transport of sediments in both new and old drainage systems, also highlighted the need for appropriate drain construction and maintenance techniques. In response, this project (more)...
