Assessment of Information Needs for Freshwater Flows into Australian Estuaries

This report was commissioned by the Fisheries Research and Development Corporation (FRDC) and Land & Water Australia (LWA) to assess the information needs for freshwater flows into estuaries.

Assessment of Information Needs for Freshwater Flows into Australian Estuaries

This report was jointly commissioned by the Fisheries Research and Development Corporation and Land & Water Australia to assess the information needs for freshwater flows into estuaries. This report is based on the results of a desk study together with the outputs from an expert workshop. It has the following objectives: create a logical framework showing the potential links between freshwater inflows and (more)...

Managing Weeds Under Future Scenarios for Environmental Flows in the Murray River

Appendix

This project examined relationships between hydrological parameters relating to flooding and the location and abundance of exotic plant species in River Murray floodplain systems.

Making the most of scant environmental flows

Maintaining the iconic river red gum and black box woodlands of the Lower Murray Valley

Presents findings from a Land & Water Australia PhD study undertaken on the Lower Murray Valley floodplain in South Australia. Primary study sites covered the region from Morgan in the west to Chowilla on the NSW border.

Benchmarking the distribution efficiency of an irrigation supply system

Project No.GMW3 - Final Report

Project objectives To benchmark the distribution efficiency (DE) of the various components of a small, open channel gravity irrigation system and irrigation return flows from farms to the surface drainage system. To develop strategies to overcome water losses in the distribution system, including the implementation of smart systems for improved channel operations, system planning and services to improve the integration of distribution systems (more)...

Irrigation, National & Regional Economies

Sustainable Irrigation Program Research Proposal

The research outlined below is based on Expressions of Interest received by, and feedback from, the Sustainable Irrigation Program Management Committee.

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.

Using market-based instruments to secure water for environmental flows

Over recent decades the extractive use of water in Australia has dramatically increased, leading to greater agricultural production and, in many instances, to the degradation of riverine ecosystems, loss of productive land and impacts on water quality and biodiversity. In response, Australian governments’ are progressing a range of water policy reforms, with recent inter-governmental agreements committing in excess of $1b to enhancing flows and environmental outcomes along the Snowy and (more)...

Natural resource buybacks and their use to secure environmental flows

Governments have committed to investigating the use of market based instruments such as ‘buybacks’ to source water for environmental needs. Buybacks are common in some natural resource sectors and have been used in the water sector as well. However, there is limited experience or research in Australia to investigate how buybacks could be structured. There has been little focus to date on alternatives to the outright purchase of entitlements, such as the buying of ‘partial’ (more)...
