Storm event-scale nutrient attenuation in constructed wetlands experiencing a Mediterranean climate: A comparison of a surface flow and hybrid surface-subsurface flow system

Abstract Among different Water Sensitive Urban Design (WSUD) options, constructed wetlands (CWs) are widely used to protect and support downstream urban waterways from stormwater nutrients. This analysis assessed the nutrient attenuation ability of a novel CW in Western Australia that…

Impact of water allocation strategies to manage groundwater resources in Western Australia: Equity and efficiency considerations

Abstract In many parts of the world groundwater is being depleting at an alarming rate. Where groundwater extraction is licenced, regulators often respond to resource depletion by reducing all individual licences by a fixed proportion. This approach can be effective…

Urban water metabolism indicators derived from a water mass balance – Bridging the gap between visions and performance assessment of urban water resource management

Abstract Improving resource management in urban areas has been enshrined in visions for achieving sustainable urban areas, but to date it has been difficult to quantify performance indicators to help identify more sustainable outcomes, especially for water resources. In this…

The most cost-effective ways to maintain public open space with less water: Perth case study

Abstract Local governments in Perth, Western Australia, use groundwater to irrigate high value public open space. Due to a sustained decline in rainfall current groundwater extraction rates are unsustainable and are set to be reduced. We investigate the cost-effectiveness of…

Detection and interpretation of anomalous water use for non-residential customers

Abstract Smart water meters can help businesses save water. But achieving this goal requires trusted algorithms for processing the data and intuitive, interactive software systems to support end users in decision making. This paper presents an algorithm and a web-based…

Spatial and temporal characterization of nutrient net uptake in a vegetated urban stream: Stream bank features leading to net uptake hotspots

Abstract Urban stream features can be used to promote nutrient retention; however, their interactions with different hydrological regimes impact nutrient cycling, decrease their retention capacity, and inhibit stream ecosystem functioning. This study analysed the temporal and spatial dynamics of the…

Hierarchical multi-taxa models inform riparian vs. hydrologic restoration of urban streams in a permeable landscape

Abstract The degradation of streams caused by urbanization tends to follow predictable patterns; however, there is a growing appreciation for heterogeneity in stream response to urbanization due to the local geoclimatic context. Furthermore, there is building evidence that streams in…

Riparian Design Guidelines to Inform the Ecological Repair of Urban Waterways

Riparian zones, the strips of land that run adjacent to streams and rivers, support an array of ecological processes important for healthy, well-functioning waterways. There is a strong incentive to manage and protect riparian zones because repairing a relatively small…

Cost-effective Strategies to Reduce Nitrogen and Phosphorus Emissions in an Urban River Catchment

Emissions of nitrogen and phosphorus from various sources into urban waterways cause algal  blooms and generally degrade delicate aquatic ecosystems. Perth’s Canning River is a prime example,  and yet protecting it from these emissions has been a policy challenge for…

Changing household water consumption practices after drought in three Australian cities

Abstract One of the major challenges of moving toward more sustainable and water sensitive futures is to change people's everyday water consumption habits. The experience of the Millennium drought in Australia (1996–2010) and water restrictions introduced during that time intervened…
