Adaptation Tipping Points of a Wetland under a Drying Climate

Abstract Wetlands experience considerable alteration to their hydrology, which typically contributes to a decline in their overall ecological integrity. Wetland management strategies aim to repair wetland hydrology and attenuate wetland loss that is associated with climate change. However, decision makers…

A Legal Obligation to Restore Wetlands by Environmental Water Allocations

Abstract Wetlands worldwide require significant restoration, especially through environmental water allocations. This article examines the Ramsar Convention (Ramsar) and the Convention on Biological Diversity (CBD) to ascertain whether they require an obligation to restore wetlands by such means. While both…

The most cost-effective ways to maintain public open space with less water

Reduced irrigation water available for public open space (POS) due to groundwater depletion is an emerging problem in many urban areas. Local governments in Perth face mounting pressure to maintain high quality POS while being driven to use less groundwater…

Review of non-market values of water sensitive systems and practices

The adoption of water sensitive systems and practices can provide tangible benefits that are easily quantifiable, such as additional water supply, and intangible benefits that are difficult to quantify, such as amenity value. As a result, intangible benefits are often…

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…

Preliminary evidence suggests freshwater turtles respond positively to an environmental water delivery during drought

Abstract Environmental flows (e-flows) are a common management tool to improve the health of flow-regulated river systems and their biota. The effect of e-flows on fish, waterbirds and vegetation has been assessed in Australia, but their influence on turtles remains…

Legal duties for environmental water provisions in Western Australia

Abstract Western Australia has not delivered on its promises to make environmental water provisions (EWPs), including to restore environmentally sustainable flows of water to waterways and wetlands. WA has prioritised water supply for consumptive use under pressure from a growing…

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…

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…
