Guidelines for Managing Soil Salinity in Groundwater Irrigated Vineyards

 This report outlines the key findings from the project:

• Rainfall percolation is the key to sustaining supplementary irrigation with saline groundwater
• At 25 years of age, salt excluding rootstocks have equal or better yield than own rooted vines and half the fruit chloride
• Soil water extractors give fast and cheap guidance on vineyard salinity status

Groundwater and Surface Water Interactions in the Fractured Rock Areas

This report entails the component of works undertaken in the Wilyabrup catchment, located in the south west of Western Australia, near the town of Cowaramup and Smith Brook catchment located in the south west of Western Australia immediately south of the town Manjimup. These catchments were selected as they are both reliant on reliable water supplies to sustain established agricultural and viticultural systems.

Sustaining perennial horticultural production

This publication explores ongoing perennial horticultural production using supplementary irrigation with saline groundwater. The role of rainfall, spatial distribution of salinity and salt-exclusion characteristics of rootstocks are among the considerations.

Indigenous Interests in Tropical Rivers: Research & Management Issues

The report was requested by Land and Water Australia (LWA) as a scoping study to provide information for their new Tropical Rivers Program.

Impacts of Groundwater Affecting Activities on Baseflow Variability and Ecological Response

Climate change and water use of native vegetation

Under climate change conditions Australia will generally be hotter and, for many parts of the country drier. Vegetation water use is strongly influenced by soil moisture availability (which is influenced by rainfall) and evaporative demand. Soil moisture will be more scarce in the future across much of the continent due to declining rainfall. The major input of water into the Australian landscape is rainfall and most rainfall (70–95%) returns to the atmosphere as (more)...

Identifying Groundwater Dependent Ecosystems

Groundwater dependent ecosystems (GDEs) are important elements in the landscape that require access to groundwater to maintain their health and vigour. They are important because of their conservation, biodiversity, ecological, social and economic value.

There are two threats to GDEs — outright loss of habitat and outright loss of groundwater resources.

Implementation

This report presents the National Framework for the assessment of EWRs of GDEs. It has been designed to assist water resource, catchment and ecosystem managers, or their advisors, in considering the needs of GDEs in water allocation planning policy.
