Elucidating relationships between disturbance and invasion in riparian zones

This project sought to develop improved riparian weed management strategies by analysing the linkages between disturbance from flood events and both weed invasion and tree recruitment in riparian areas. Analysis of an existing dataset containing…

Changing Irrigation Systems and Management in the Harvey Irrigation Area

The project is examining issues of water use efficiency (WUE) in the South West Irrigation Area (hereafter called the Harvey Irrigation Area). A significant WUE issue is whether water savings, improved pasture yields and farm productivity can be achieved through sprinkler (centre pivot) irrigation of dairy pasture in comparison with traditional surface bay irrigation (often called flood irrigation). This project is a case study conducted on (more)...

Irrigation Insights 2 - Subsurface Drainage Design and Management Practices in Irrigated Areas of Australia

It is widely understood that irrigation development results in deep percolation past the rootzone, which recharges the groundwater. With flood irrigation, watertables often rise at around 0.5 m a year until a new equilibrium is established where the watertable fluctuates from the soil surface to around 3 m deep. A significant part of all irrigation areas in Australia are currently in this condition or approaching such equilibrium. Irrigation areas in southeastern Australia, particularly in the Murray (more)...

Establishing a process to improve irrigation automation

Irrigated dairying is a major farming activity in the Murray Valley Irrigation Area (MVIA), in north-east Victoria, contributing greatly to this State’s economy. Most of the dairy farmers in this area flood irrigate their pastures. For better pasture quality and quantity, efficient irrigation is vital. The project entitled "Establishing a Process to Improve Irrigation Automation," realising the importance of irrigation for the dairy industry, has defined some (more)...
