Journal Papers

This page features some of the articles written by the partnership’s researchers. A complete list (of all publications) can be found via the following links: Journal articles, Book chapters and Conference proceedings. Many of these are available to Melbourne Water employees, by contacting the Waterways Knowledge Broker or the researcher directly.

Restoring in‐stream habitat in urban catchments: Modify flow or the channel?

read it here (EcoHydrology 2019)

In this article, researchers from the MWRPP uses two‐dimensional hydraulic modelling to examine the relative roles of
flow and channel morphology in setting hydraulic conditions. They found substantial differences in hydraulic conditions between urban and natural reaches.

And the conclusion? The research suggests that once channel form has been degraded, mitigating urbanization impacts on flow regime cannot maintain “natural” channel hydraulics. Management approaches therefore must protect channel morphology from change.

Identifying critical inundation thresholds to maintain vegetation cover in stormwater treatment wetlands.

In this article, researchers from the MWRPP investigated the relationship between the water level regime and vegetation cover in 19 stormwater wetlands. They found a strong relationship between the median water level and vegetation cover, and that poor outlet efficiency, rather than the hydraulic loading rate, was driving the water level regime.

And the conclusion? There is now firm evidence and support for identifying (in design guidelines) the threshold depths for emergent macrophytes in stormwater wetlands. The researchers recommend that adjustable outlets in combination with real-time water level monitoring should be used to maintain a suitable water level regime in stormwater wetlands fed by dynamic urban catchments.

Where does infiltrated stormwater go? Interactions with vegetation and subsurface anthropogenic features.

In this article, researchers from the MWRPP tracked the fate of infiltrated stormwater from the large biofilter at Wicks Reserve (The Basin), using a network of piezometers for over three years. Monthly water balance calculations indicated that in summer, most of the infiltrated stormwater was evapotranspired by the vegetation downslope of the basin, and thus did not reach the receiving stream. In the colder months, some infiltrated stormwater did reach the stream as plant water use declined.

And the conclusion? Anthropogenic disturbances were found to strongly interact with the infiltrated water, with the study providing evidence that the fate of infiltrated stormwater is complex, and that infiltrated stormwater does not always reach receiving streams as baseflow as is often assumed.

Improving the Multi-Objective Performance of Rainwater Harvesting Systems Using Real-Time Control Technology.

In this article, Partnership researchers investigated the enhancement of rainwater tanks via Real Time Control (RTC) technology. Using continuous simulation, they modeled the ability of different tank systems to achieve water supply, stormwater retention and baseflow objectives. They concluded that the active release mechanism employing RTC technology exhibits great promise; allowing a tank system to perform optimally across a wider range of climatic conditions.

And the conclusion? Rainwater tanks using RTC technology were better at concurrently achieving water supply, stormwater retention and baseflow restoration benefits, compared to other types of tank systems.
