ABSTRACT Water is a critical issue for governments and community in an Australian context, and internationally. First Peoples of Australia, its Indigenous peoples, have over 65,000 years of connection and understanding of water, held by more than 250 distinct Indigenous Nations that occur from the wet tropics, through desert country and south to the temperate zone, river lands and alpine regions. The value of water is central to Indigenous peoples’ being and culture, but since European colonisation in 1788, water has been subject to pumping, storage, diversion, extraction and pollution and without Indigenous people’s council. Most recently, water has been attributed a market value to sell and trade on a market that moves up and down with availability (drought, flood or in-between). Indigenous peoples have very small water entitlements despite the high value they place on water and the strong connection water has to their sense of identity, spirituality and culture. There is both a need and a great opportunity for Indigenous people to uphold and protect their water values through Indigenous-grounded methodologies or Indigenous-led water research, and so as to integrate Indigenous water knowledge into science and policy.

ABSTRACT This paper documents Indigenous Traditional Owners’ water values, rights, and interests from the Mitchell catchment in North Queensland. It is the first analysis of the catchment that links Indigenous water values, rights and interests with specific water resource assessment and development considerations. The paper highlights how relational and reciprocal values frame Traditional Owner responsibilities and obligations through water across generations, across geography, to places, and with the non-human and spiritual entities living on their traditional lands. This ethos of relatedness shapes the way Indigenous peoples want to be engaged in water assessments and planning processes – such processes must focus first on local and regional relationships, where Indigenous actors are central to the coordination of a wider multi-interest governance process. Relatedness relies on building trust, continuous learning, and communication to encompass different values amongst people who are inter-dependent in their use of and relationship with water. Traditional Owners are seeking new platforms that bring multiple knowledges to water resource assessments and planning processes – where Indigenous ways of knowing are included with science, policy, industry, conservation, and community knowledges into an adaptive process focused on long-term sustainability.

ABSTRACT Safe drinking water provision in remote Australian Indigenous communities can raise many challenges. An initiative to enhance drinking water treatment was piloted in Australia’s remote Torres Strait Islands. It was co-designed through close involvement of Torres Strait Islander local government officers and water operators. Data collection and analysis was undertaken independent researchers to assess the effectiveness of the pilot, drawing on both quantitative and qualitative sources, including field visits to the two Torres Strait Islands. The findings identified three key features for an effective programme of safe water delivery: appropriate infrastructure that is ‘fit for purpose, place and people’; mentoring and technical support for remotely located water operators, and cooperation across relevant state and local government agencies. The pilot initiative has adaptive potential for other remote communities and for other basic services, including wastewater treatment and solid waste management.

ABSTRACT The ‘Living Waters, Law First’ water governance framework centres Living Waters, First Law and the health/well-being of people and Country. The framework is based on a groundwater policy position developed by the Walalakoo Aboriginal Corporation (WAC), the Nyikina and Mangala peoples’ native title corporation, in the West Kimberley, Western Australia in 2018. This article celebrates Traditional Owner’s pragmatic decolonising strategies. It explores the emerging conceptual challenges to the status quo by comparing the Living Waters, First Law framework to Australia’s settler state water governance framework, represented by the National Water Initiative. Bacchi’s ‘what is the problem represented to be’ approach is used to interrogate the underlying assumptions and logics (2009). We find that there are incommensurable differences with First Law and the Australian water reform agenda. Yet, our analysis also suggests ‘bridges’ in relation to sustainability, benefits and responsibilities could promote dialogues towards decolonial water futures.

ABSTRACT Water places have been critical to central Australian Indigenous peoples for thousands of years. However, many waterhole communities have been degraded by factors including invasion by large feral herbivores and non-native plants. We document the restoration of two waterholes near Santa Teresa (Ltyentye Apurte), with a focus on culturally significant plants. We described plant communities around waterholes in 2007, before fences were erected to exclude large feral animals, and again in 2018. Plant cover and diversity were higher after fencing and the occurrence of culturally significant plants greatly increased. However, invasive buffel grass was the dominant ground cover after fencing and will require active suppression to allow culturally significant native plants to proliferate. Traditional Owners identified excellent opportunities to achieve restoration through educating young people, with a focus on sharing intergenerational knowledge and engaging local Indigenous rangers in management, enabling them to meet the traditional obligations to care for country.

Before any major hydraulic engineering project is undertaken for planning, designing, construction, or revamping and rehabilitation some kind of model study is but a necessity. Depending upon the time, resources and, significance of the project, the study could be done only on the paper and computer screen using some graphical, analytical or, statistical software and tools, or it could be combined with the more expensive and time consuming physical model study also. This chapter focuses on the question as to why the physical modeling should be reintroduced into engineering practice because of the modern techniques and systems now available for construction, operation and, data analysis of these physical models.

Discharging accumulated bilge water from the ship is very important in order to maintain its stability and safety. However, the bilge water that contains contaminants, including waste oils and oily wastes, must be treated prior discharging to the sea. The International Convention for the Prevention of Pollution from Ships (MARPOL) has set strict oil discharge limit in order to minimize sea pollution. Thus, an efficient oil–water separator must be installed to separate the oil from the bilge water. This chapter introduces and discusses the working mechanisms, as well as advantages and disadvantages of the available oil–water separation techniques for bilge water treatment, which include gravitational, centrifugation, flotation, coagulation and flocculation, biological processes as well as absorption and adsorption.

ABSTRACT Worldwide, floodplains have been alienated from river channels for flood protection and water resource development, but several recent programs have restored connectivity, generating considerable ecological and , socio-economic benefits. In Australia, under the Murray-Darling Basin Plan, water purchased from irrigators is used to restore wetlands. Maximising ecological benefits with limited water requires constraints relaxation, whereby high flow volumes for ecologically effective floods are released from headwater dams and allowed to flood public and private land en route to wetlands downstream, requiring infrastructure works and rights to inundate private land. We examined five focal areas in the Basin Constraints Management Strategy to determine ecosystem services benefits generated by floods on land between dams and target wetlands We found multiple examples where significant co-benefits could be realised but had not been identified. Accordingly, the assessment of costs and benefits was primarily focussed on costs. We categorised ecosystem services for each focal area as of low, medium or high importance andassigned monetary values where possible. Regulating and cultural services, rather than provisioning services, ranked highest across all focus areas, including groundwater recharge, regulation of riparian habitat quality, aesthetic appreciation, recreation and tourism, Indigenous and community values. The business cases seek to maximise costs and thus the transfer of public funds in compensation to landholders. However, there are important public policy considerations of equity, accountability and transparency, including proof of damage prior to compensation, as well as offsetting losses against ecosystem services benefits. We consider that an ecosystem services approach could greatly improve acceptance of constraints relaxation amongst landholders and the development of novel policy options and instruments that can help advance the implementation of the Basin Plan.

ABSTRACT As urban populations expand globally, the associated increase in urban land cover directly impacts the social and environmental amenity of natural assets, including waterways. The primary driver of urban waterway degradation changes in land uses which results in altered hydrology – from stormwater runoff, and where present, wastewater treatment plant discharge. Whilst the impacts of pollutants are relatively well regulated via public policy, a gap remains for the management of flow regime modification. The Urban Streamflow Impact Assessment (USIA) was developed to fill this management and planning knowledge gap. The approach begins with the identification of waterway values (social, ecological and geomorphic) then explicitly links these values to streamflow characteristics using hydraulic and hydrologic metrics. USIA was applied to a case study in Western Sydney and demonstrated the loss of values associated with ‘business-as-usual’ approaches to stormwater and wastewater management. Conventional stormwater management approaches do not remove enough excess flow to meet reasonable outcomes for the waterway. This excess runoff is increasingly seen as a resource and opportunity for improving water security and liveability. USIA is consistent with regulatory frameworks and can be applied across developing and established urban catchments to provide explicit input to planning controls. The approach is appropriate at multiple scales, informing urban planning from a broad strategic level through to detailed design. By linking social and ecological values with geomorphic and flow requirements, the approach enables an understanding of which management approaches could allow desirable waterway outcomes to be met.
