Flow requirements and resource delivery to the Lower Murray Lakes and Northern Coorong

As discussed in the previous milestone reports, the drawdown of water levels in the Lower Lakes to unprecedented levels has provided an additional focus for the project. This has been done to provide relevant information to the managers and assist with both the short-term and long-term management of the region. It has included investigating the changes water quality during drawdown and likely changes in water quality upon reflooding the lakes.

Root Zone Salinity Risks in the Lower Murray Districts

As a result of improved irrigation management and systems, growers in the Lower Murray (Riverland-Sunraysia) horticultural region have improved their water use efficiency (WUE) over the past two decades from about 50% to about 80%. However a negative consequence of this achievement is the emerging risk of salinity build-up in the root zone, threatening the sustainability of the region (Biswas et al. 2005a; Biswas et al. 2005b). The amount of irrigation applied must account for (more)...

Salinity impact on Lower Murray horticulture

The project was developed to test the hypothesis: ‘a depressed leaching efficiency (LE) in the Lower Murray irrigation districts raises the root zone salinity and, improved water use efficiency (WUE) has an upper limit determined by that field’s LE and its variance’. The specific objectives were to: Determine/update the salinity relationships for irrigated horticulture along the Lower (more)...

Salinity Impact on Horticulture in the Lower Murray

Sustainable Irrigation Program Research Proposal

The high value horticultural production systems along the lower Murray is likely to continue to suffer from increasing salinity levels in irrigation water despite improved irrigation management, saline groundwater interception and future environmental flows. The effects that variations in leaching efficiency and irrigation management have on soil salinity are also inadequately quantified.
