Investigating lake/groundwater interactions at Lake Tutchewop

Salinity is an on-going environmental concern that causes damage to agricultural land, downstream water users, aquatic ecosystems and biodiversity, as well as to regional and urban infrastructure. One strategy to manage increasing salinity in the Murray Darling Basin is the construction of 13 major salt interception schemes that divert 550,000 tonnes of salt away from the Murray River each year (Figure 1). The Barr Creek Drainage Disposal Scheme is one of these schemes diverting saline water into (more)...

Coordinating Deep Drainage Research in the Northern Darling Basin - Final Report

A key issue identified by the research community working with the cotton industry was the lack of understanding and acceptance of the concept of deep drainage. Deep drainage is defined as the part of the water (applied to the surface and as rainfall or irrigation) that moves past the rootzone. In general the existing paradigm was “cotton soils don’t leak”. However, the research community related to the Australian Cotton CRC (ACCRC) (more)...

Views on Irrigation Policy in Australia and Experiences from Brazil and China

Water policy in Australia is undergoing considerable and unprecedented change. Most recently, the emphasis on the sustainable management of water resources in the Murray Darling Basin has seen a shift of control from the States to the Commonwealth. The declining availability of water and the subsequent approaches taken by governments have come under increasing scrutiny from the public. Indeed, the actions associated with water policy in Australia, particularly water used for irrigated agriculture, have (more)...

Implications of water reforms for the national economy

FROM HUMBLE BEGINNINGS in the 1880s by individual farmers along inland rivers and, in particular, the efforts of the Chaffey brothers at Renmark and Mildura in 1887, the irrigation industries in Australia have expanded to where they now use three quarters of all water used, have a combined area of about 2.6 million hectares under irrigation and produce agricultural outputs worth over $9 billion. Irrigation industries are an (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)...
