WERGing from home
Like so many of late, researchers from the Waterways Ecosystem Research Group (WERG) are quickly adapting to the new ‘working-from-home’ scenario. While they are unable to undertake any field work, the team is continuing to implement the waterway partnership’s research projects by re-arranging tasks – using this time to compile and analyse data, conduct literature reviews and write reports. And while most researchers are getting by with a desk in the spare bedroom, others have had to be a little more prepared and inventive. This ranges from setting up mini-technology laboratories to continue work on the development of remote monitoring sensors….to transporting microscopes home to enable macro-invertebrate identification. It even includes converting a laundry to a temporary wet lab! So, while research outcomes in coming months will differ to what was originally expected for this time, the research projects are still advancing. We will continue to communicate progress over the coming weeks, but of course, if you want to talk to any of the project leaders about any of this, feel free to contact them.

Groundwater use
Field work at Wicks Reserve for Project B4:Groundwater is now complete, with the final validation campaign for sapflow data having been collected in early March. The preliminary results from this research are exciting, with quite strong evidence that the Wicks Reserve Bio-Infiltration enhances water availability to the downstream trees (relative to the upstream control trees), allowing them to continue transpiring at their maximum rate even during dry periods. This has important implications for urban water balance, urban microclimate and the use of infiltration. For further information you can contact: Tim Fletcher, Matt Burns, Fern Yong or Jasmin Thom

A boost for Street Trees research
Research project C1.1: Street Trees has enjoyed some recent grant success, being awarded $130K from Melton Shire Council for a 2-year research project on passive irrigation, as well as $105K through Melbourne Water’s Incentives Scheme Grant – a collaboration with Moreland City Council and Cardinia Shire. Additionally, the project’s leaders have been facilitating the establishment of a ‘Passive Irrigation Network’, which currently has ~70 members from 19 Local Governments and multiple state organisations. The purpose of the network is to promote knowledge sharing and to create opportunities to test some ambitious new designs for streetscapes. For more information, contact Chris Szota

New report on prioritizing cost-effective actions
A recently completed report documents the development and application of the habitat suitability models used to support multiple stages of the community co-developed Healthy Waterways Strategy 2018. Focusing on natural environmental and human-induced catchment influences on aquatic biodiversity, it details scenarios and management action prioritisation across the Port Phillip and Westernport region using the conservation planning software, Zonation. These tools integrated best-available data and knowledge to explore strategic concerns for long-term planning and to conduct region-wide scenario and prioritisation analyses. They also enabled outputs of plausible future scenarios to be summarised, mapped and shared with stakeholders to support deliberations that helped inform priority actions and target-setting in the Healthy Waterways Strategy 2018. Email Darren Bos for a copy of the report.

This map shows the ‘optimal’ action for all 8,233 reaches in the Melbourne Water region, which was used in the scenario and prioritisation analyses.

New Network Stream Layer
A new stream network layer (V1.0) has been developed for the Port Phillip & Westernport Catchment. This new layer has a range of advantages, including: augmenting the existing stream line data to include small headwater streams missing from earlier stream data; standardising names of streams across the region, giving each stream a unique name and code; provide a unique meaningful code for each reach, linked to existing codes such as Melbourne Water’s asset identifiers; and delineates a sub-catchment boundary derived from a 5-m digital elevation model for each reach. Work is now underway to incorporate this new data set into Melbourne Water mapping and information systems. In the meantime, you can start exploring the new layer (and download the manual) by visiting

Workshop: Stormwater management to protect streams
The Waterways Ecosystem Research Group recently hosted a workshop to discuss stormwater management to protect urban streams. The workshop adopted a systems thinking approach, exploring the concepts of leverage points and collective impact. The goal of the workshop was to work together to identify how to achieve the greatest impact in terms of stormwater management that truly protects streams and, hopefully, the best way forward to address them collectively. Participants were drawn from a wide range of disciplines and organisations to ensure the issue was considered from all angles. And the outcome of the workshop? To meet again, to discuss further this very complex issue.

Geomorphic disturbance and channel change
A recent report prepared for research project A3: Channelisation provides valuable foundation information around channelisation in urban waterways. The report, titled “Predicting geomorphic disturbance and stream channel change in urban catchments” provides i) a summary of previous developments in the field of predictive channel morphology models, and ii) a review of current data, that outlines the context of the study area and relevant data sources and gaps. It’s the first step in the project – that is aiming to develop a Model of River Physical Habitat (MoRPH) and resulting spatial layer. A copy of the report can be obtained by emailing Darren Bos

Awards season
The MWRPP and it’s partners have featured in some of the recent awards programs coordinated by the water management industry. At the the Victorian Water Awards:

The WERG descends on Novatech Conference
Eight members of the Waterways Ecosystem Research Group (WERG) are travelling to Lyon (France) to participate in the 10th edition of the Novatech Conference (1-5 July). Novatech is an internationally recognised event that promotes strategies and solutions for integrated and sustainable water management in the city. Members of the WERG will deliver (or co-present) 5 oral and 3 poster presentations relating to the research projects of the Waterways Research Partnership. WERG researchers will also lead the one day workshop: Urban Water Monitoring, where they will share their experience (and seek advice) on topics like: the use of thermal cameras for looking at groundwater fluxes; building weirs to measure flows in small open waterways and the best ways to measure flow in steeply graded pipes.

Wetland Monitoring site selection complete
Project B3: Constructed Wetlands has completed a critical foundation step. After a huge effort to review and assess the ‘as-constructed’ drawings for 77 wetlands, 26 sites have now been chosen for this monitoring study. The next phase of the project is to purchase and deploy water level sensors at all 26 sites. The project involves a strong collaboration with A3P, who are currently preparing a literature review: “Stormwater wetland performance indicators: a review of current and emerging methods and techniques”. At its conclusion, Project B3: Constructed Wetlands hopes to develop indicators of wetland treatment performance. Further details on this projects can be found under Research Projects/Active. Any Melbourne Water employee interested in participating in this project is encouraged to contact either Rachael Bathgate or Rhys Coleman.

Researchers from the WERG investigate an outlet pit at the Fulton Road Wetland, discussing the best location for logging equipment.

Long term protection for Little Stringybark Creek.
The Environmental Significance Overlay (ESO) for the catchment of Little Stringybark Creek is now a permanent planning control, with the corresponding planning scheme amendment gazetted in May. The process to have this protection made permanant has been a long and involved, starting with a pilot program in 2013. The ESO ensures that any new development in the catchment, greater than 10m2, meets a minimum standard of stormwater control. Congratulations to all those involved in achieving this goal.

Waterway Physical Form Training
Staff from Melbourne Water recently participated in a two day training event to learn more about the physical form of waterways, and how to protect, manage and restore for stream health. The two-day program was coordinated by the MWRPP and included a mix of theory, practical exercises and a full day in the field. The course was well received, with over 20 participants, all of whom reported they learnt a lot that was directly applicable to their roles in Melbourne Water. It is likely that the course will be run again soon, so contact Rachael Bathgate or Darren Bos to register your interest.

New Research Program
What are the critical assumptions between Melbourne Water interventions and environmental condition? How do sediments move within a catchment? How well are privately owned rainwater tanks managed? These questions, along with many others, will form the basis for a suite of new research projects for the waterway-research partnership. Melbourne Water and The University of Melbourne have agreed to a collaborative research program for 2018/19, with 17 projects receiving joint funding from both organisations (approx. $4m). The full list of projects can be found under Research Projects/Active, along with a summary of their research directions and proposed outcomes. Any Melbourne Water employee interested in participating in a research project(s) are encouraged to contact either Rachael Bathgate or Rhys Coleman.

New Research Note
How does the local community in Sunbury interact with and perceive local waterways in the present and potential form? This was a principle question of research in the latest Research Note produced by the partnership. This two-page summary (found here) highlights the wide range of value attributes identified by the community and possible discrepancies between their perceptions and those of management agencies.
