Research project highlights

WRL is at the frontier of water engineering research.

We pride ourselves on paving the way to discover and deliver new ideas, leading conversations and delivering solutions that have a positive impact, be it new technologies to monitor and quantify changing coastlines, or restoring wetlands to preserve wildlife and ecological communities.

Caseys Beach 1
Caseys Beach seawall upgrade
Eurobodalla Shire Council engaged WRL in partnership with Aurecon to prepare the design for the Caseys Beach seawall upgrade; an 80 m length of the southern part of the seawall to ensure the stability of the foreshore and prevent undermining of the sewage pumping station... More
2020 Mayes Swamp within the Clybucca Wetlands
Clybucca Wetlands management options study
The low-lying areas of Mayes Swamp and Doughboy Swamp on the Collombatti-Clybucca floodplain were historically natural backswamp wetlands. Significant drainage infrastructure constructed over the 20th century has promoted rapid drainage and lower surface and groundwater levels... More
2012 Cook Islands COPED
Coastal adaptation needs for extreme events and climate change, Avarua, Rarotonga, Cook Islands
WRL undertook a project spanning 8 months in Avarua, the main town of Rarotonga, Cook Islands. Leading research to calculate the impact that more extreme storm events will have, including topographic and bathymetric data collection, hazard mapping, analysis of previous cyclone events and damage, analysis and predictions of wave processes and inundation during extreme events, and consideration of the effects of climate change on risk...

CoastSnapLogo
CoastSnap
CoastSnap is a low-cost community beach monitoring technology that turns the smartphones found in most people’s pockets into powerful coastal monitoring devices. From humble beginnings on Sydney's Northern Beaches, WRL's CoastSnap stations can now be found worldwide!.. More
Eurobodalla CH assessment 1
Eurobodalla Shire Council coastal hazard assessment
Eurobodalla Shire Council, located on the NSW south coast, commissioned WRL to prepare a coastal hazard assessment for 17 of their most vulnerable beaches. .. More
Water
Hunter River water quality model
WRL recently supported a Hunter Water Corporation preliminary planning exercise looking at the sustainable effluent management and potential re-use of wastewater in the lower Hunter River catchment... More
Newcastle
Hunter scoping study
Various hydrodynamic modelling studies have previously been undertaken for the Hunter Estuary. In many cases these projects repeat the work of previous studies and the project outcomes are isolated. The aim of this project is to provide a coordinated whole-of-government modelling approach using the best available data, produce consistent results, reduce uncertainty and be available for use by regulators, proponents and decision-makers...

Kingscliff seawall design
Tweed Shire Council engaged WRL in partnership with Haskoning Australia to prepare the design for a long-term terminal seawall. Following consideration of a range of preliminary seawall design types (including an alternative protection scheme with a groyne field); a composite seawall design was adopted... More
Manly
Manly coastal hazard assessment
Manly beaches are susceptible to significant erosion during extreme storm events and have a long history of failure of their protection works. WRL was commissioned to undertake a comprehensive investigation to identify and quantify coastal risks... More
oceanlinx
Oceanlinx wave energy system physical modelling
The Oceanlinx system converts the flow of air above an oscillating water column into electrical energy via a mechanical turbine. Wave flume tests were undertaken independently on two different types of designs in the 3 m wave flume at WRL... More
Wave testing of oyster bags
Oyster reef restoration project
A novel technique has been proposed to encourage oyster reef restoration and reduce intertidal riverbank erosion. This innovation uses seeded oyster shells in coconut fibre bags. Deliberately utilising only organic materials, the fibres will naturally decay in time with the intention of leaving a new, intact oyster reef structure behind... More
WatermarkCoal
Peer review of Watermark Coal groundwater modelling report
Shenhua Australian Holdings submitted an Environmental Impact Statement to NSW regulators for the Watermark Coal Project. The proposal was for an open cut coal mine adjacent to the Mooki River. WRL was commissioned to provide independent review of the conceptual and numerical groundwater modelling... More
bounty-bay-1
Physical modelling of Bounty Bay breakwater, Pitcairn Island
Bounty Bay is the primary landing point for access onto Pitcairn Island, with the coastline being extremely rugged for most parts. WRL was commissioned to undertake a physical modelling investigation of the proposed breakwater and Bounty Bay harbour... More
port-fairy-coastal-hazard-assessment
Port Fairy coastal hazard assessment
WRL undertook a detailed sea level rise and coastal hazard assessment for Moyne Shire Council, Victoria. This project is part of the Future Coasts Program, the purpose of which is to assist in better understanding and planning for the risks associated with sea level rise and storm surge... More
2020 Laura Montano in the Scrivener Dam model
Scrivener Dam physical model
WRL was commissioned by the National Capital Authority to construct and test a 1:40 scale physical model of Scrivener Dam in WRL’s hydraulics laboratory at Manly Vale... More
Tomago_Wetland_restoration_1
Tomago Wetland restoration project
Winner of multiple environmental awards, this project has transformed the Tomago Wetland site from a large acidic landscape into a restored productive tidal wetland. The wetland has being created to compensate for migratory wading bird habitat destroyed elsewhere in the lower Hunter River estuary. .. More
UNSW Tube Fishway
Tube fishway project
Aiming to restore fish migration across dams and weirs, UNSW researchers are combining their expertise in fish ecology and hydraulic engineering to develop a Tube Fishway; which sets out to provide effective upstream fish passage through a tube using a conduit system... More
2020 Project Engineer Alice Harrison observes high concentrations of iron floc in Tuckean Swamp, Richmond River
Tuckean Swamp drainage options study
Tuckean Swamp is a 6,000 hectare low-lying floodplain located on the Richmond River, which has been extensively drained since the 1880’s... More
Thirlmere Lakes
The mystery of Thirlmere Lakes
During the past decade, water levels in the Thirlmere Lakes have varied from full in 2016 to completely dry between October 2018 and February 2020. These variations have raised concerns with the local community and left them wondering; "Where has all the water gone in Thirlmere Lakes?".. More
