There is an urgent need for ecosystem restoration. The United Nations has declared 2021-2030 the Decade of Ecosystem Restoration. This global effort aims to massively up-scale the restoration of degraded and destroyed ecosystems as a proven measure to restore ecosystem services, fight the climate crisis and enhance food security, water supply and biodiversity.
The award-winning Ecosystems Engineering group at UNSW Sydney’s Water Research Laboratory (EcoEng @ WRL) is a worldwide leader, with a twenty-year track record, in developing practical solutions for the successful restoration and functional recovery of damaged, contaminated or endangered ecosystems. Major projects include tidal and riverine wetlands, estuaries and inland waterways.
EcoEng @ WRL places a strong emphasis on partnerships, collaborations and joint studies. While our research focuses on the water-based processes in the environment, we value our partnerships with the ecological, economic, management and engagement experts. We encourage other groups to develop partnerships and establish contacts to ensure we have the best understanding of a community, including local concerns and global implications.
EcoEng @ WRL is led by Professor William Glamore, a highly awarded physical scientist and engineer specialising in ecosystem engineering and the blue economy. With an outstanding, enthusiastic and committed team of scientists, engineers and cross-disciplinary colleagues, the group draws upon its extensive research and experience to provide innovative and effective answers to complex ecosystem engineering questions throughout Australia and overseas.
Key areas of EcoEng @ WRL
Restoration and creation of wetlands and waterways: Nature is complex. Endangered ecological communities exist in a fine balance, influenced by numerous factors. Over the past 20+ years we have restored some of the largest and most complex ecosystems in Australia. Project examples are provided below.
Priority decisions and engagement: Wicked problems require, prioritised solutions. We utilise several engineering/project management decision-making software systems to prioritise restoration actions, climate vulnerability, economic benefit analyses, etc. We also regularly work with local communities and government to develop educational modules and demonstration projects.
Remediation of contaminated or threatened ecosystems: Eco-engineering combines engineering principles with ecosystem restoration practice. One of our key strengths is linking these disciplines to restore waterway health, redesign landscapes and create new habitats that are safe for the community and based on sound ecological principles. To date, we have specialised in acidic, eutrophic, and PFAS contaminated environments and associated remediation.
Climate Change assessment and response: Exploring and quantifying local scale impacts, assessing waterway risk, designing adaptation strategies and infrastructure, using physical and numerical models for further understanding, communicating with stakeholders and communities.

Climate change in estuaries – risk assessment guide
This project was awarded the 2019 NSW Coastal Management Award for Innovation at the 28th Annual NSW Coastal Conference.
Assessing the impacts of climate change in estuaries is a complex task. To help navigate this complexity, a multi-report guide has been designed by EcoEng@WRL along with project partners and colleagues at NSW Office of the Environment and Heritage, Sydney Institute of Marine Science, and Macquarie University, for estuarine managers, scientists, practitioners and coastal communities.

Eco-Thresholds, a global database of ecological thresholds for estuarine species
This database was created as a tool to facilitate public access to meta-data on species-specific environmental thresholds necessary for assessing climate change risk in NSW estuaries.
