Minimising damage from water recovery

Project details

Objective:

To determine appropriate wetting and drying strategies in inland wetlands to minimise formation of sulfidic sediments, and provide environmental water managers with tools and guidelines on how to best manage inland wetlands to prevent the buildup of acid sulfate soils, and how to remediate affected systems.

Funding:

Up to $517,520 plus applicable GST from the Australian Government towards costs associated with supporting the work program. Total value of the project is $805,450 with $287,930 contributed by NSW Murray Wetlands Working Group Inc and Murray Darling Freshwater Research Centre.

Jurisdiction:

Multi state

Commenced:

May 2007

Completed: March 2011

About the project

This project is being undertaken by the NSW Murray Wetlands Working Group (MWWG) and the Murray Darling Freshwater Research Centre and is designed to determine appropriate wetting and drying strategies in inland wetlands to minimise formation of sulfidic sediments. It will provide environmental water managers with tools and guidelines on how to best manage inland wetlands to prevent the buildup of acid sulfate soils, and how to remediate affected systems. The tool will be tested for national applicability across different inland wetland regions of Australia affected and potentially affected by this problem.

Project benefits

This project will advance National Water Initiative objectives towards improved adaptive management practices to meet environmental and other public benefit outcomes by giving environmental water managers a decision support tool to assist them in reducing the build-up of sulfidic sediments in inland wetlands, including for high-conservation value aquatic ecosystems.

The tool will be widely disseminated through MWWG and Murray Darling Freshwater Research Centre networks using MWWG's communication strategy and through a multi-jurisdictional technical committee established by this project. 

The outcomes will be guidelines and a refined decision-support tool to manage inland wetlands and minimise formation of sulfidic sediments. The tool and guidelines will also be useful in the remediation of systems presently affected by sulfidic sediments.
