Abstract:

This thesis investigates whether different public accountability forums interact with one another when they oversee the same decision maker. It contributes to the larger study of how decision makers are held to account in constitutional democracies where the simultaneous operation of multiple accountability relationships has become routine. Looking beyond the dominant assumption that multiple forums autonomously assess a decision maker's accountability against different and diverging standards, I aim to understand whether forums can influence the standards against which other forums evaluate t

Abstract:

Dams and weirs are widely implicated in large-scale declines in both the range and abundance of aquatic fauna. Although many factors are involved, such declines are commonly attributed to the prevention or reduction of migration, reductions in available habitat, alteration of natural flow regimes and changes to physicochemical characteristics. In Australia, studies into the ecological effects of these impacts are limited, and have concentrated mainly on species of recreational and commercial importance. Subsequently, the adverse effects of dams and weirs, and suitable methods of mitigation, re

The Murray Darling Basin (MDB) is Australia’s largest river and wetlands network and has enormous environmental, economic and cultural importance. The over 30,000 wetlands of the MDB floodplains are an essential element of this vast and complex river ecosystem. However, the water dependent ecosystems of the MDB have been modified, largely to service irrigation and consumptive human needs. Ensuring wetlands receive water is essential to the survival of the MDB, and the process of managing this water is investigated herein.

Abstract:

Many aspects concerning the association of riverine fish with in-channel habitat remain poorly understood, greatly hindering the ability of researchers and managers to address declines in fish assemblages. Recent insights gained from landscape ecology suggest that small, uni-scalar approaches are unlikely to effectively determine those factors that influence riverine structure and function and mediate fish-habitat associations. There appears to be merit in using multiple-scale designs built upon a geomorphologically-derived hierarchy to bridge small, intermediate and large spatial scales in la

Extensive coastal acid sulfate soil (CASS) oxidation was observed in the River Murray Estuary (RME), South Australia, during an extreme drought (the Millennium Drought, 1996–2010). CASS oxidation causes significant surface water and porewater acidity, and the mobilisation of toxicants, negatively impacting proximal ecosystems and infrastructure. In this thesis I argue that the Millennium Drought acidification event provides a test case globally for how meteorological drought triggers extreme CASS oxidation, and how other variables can exacerbate the issue.

Abstract:

Water allocation is a fundamental part of water resources management. Water allocation is often a contested process because it involves multiple uses and users of water. Issues of justice arise when resources are, or are perceived to be, in short supply. When water is allocated the rules for the distribution of the resource may result in just outcomes for some stakeholders but may create injustices for other stakeholders. Issues of scale thus form an important component of water allocation. This thesis draws from an amalgam of ideas on justice, scale and water management and aims to present a

The Murray Darling Basin (MDB) is a major irrigated agricultural region known as the food bowl of Australia. Over-allocation of water rights to irrigation in the MDB has mimicked a tragedy of the commons and has led to the degradation of the ecosystem of rivers in the basin. Competition between environment and agriculture is at the heart of the problem. As water in the river systems is semicommon, where private and common rights coexist and interact due to the fluid nature of the resource, employing an exclusion strategy is difficult.

This thesis examines the role of inter-judisdictional institutions in the Murray-Darling Basin and discusses the potential impact of the National Water Initiative approved by the Council of Australian Governments in June 2004. Over the last century there have been two periods during which decision makers attempted to craft or re-craft interjurisdictional water management arrangements to suit the priorities of their times. This thesis suggests that the early twenty-first century shuold be another, Central is the argument that despite attempts to introduce a form of coordinated basin-wide manage

Abstract:

Research Doctorate - Doctor of Philosophy (PhD)<br>The impacts of multi-temporal scale climate variability occurring over the Pacific and Indian Oceans on the rainfall and runoff regimes of eastern Australia are explored in this thesis. Three modes of natural climate variability are studied, the El Niño/Southern Oscillation (ENSO), the Interdecadal Pacific Oscillation (IPO) and the Indian Ocean Dipole (IOD). An analysis of historical rainfall and streamflow data for Queensland (QLD), New South Wales (NSW) and Victoria (VIC) reveals strong relationships between indices of ENSO and IPO variabili

Abstract:

A full appreciation of the extent and significance of acid sulfate soils (ASS) in Australia's inland environments has only recently been realised, in contrast to ASS in Australia’s modern-day coastal zones, which have been well studied over the last four decades. Investigations into the inland ASS systems of the Murray-Darling Basin (MDB), Australia's largest river system, did not occur with any intensity prior to 2006. A number of key knowledge gaps exist concerning the occurrence, properties and behaviour of inland ASS systems in the MDB. These knowledge gaps, combined with the ecological an

Geochemical tracers such as radiogenic strontium (87Sr/86Sr), oxygen-18 (𝛿𝛿18O) and deuterium (𝛿𝛿D) are considered useful in the understanding of catchment hydrology and plant water use, and in this study, 87Sr/86Sr, 𝛿𝛿18O and 𝛿𝛿D isotopes were used accordingly to better comprehend local hydrology and water use behaviour patterns of Black Box trees on the Calperum Floodplain, South A

Abstract:

Freshwater turtle populations have been declining globally due to a combination of natural and anthropogenic factors, with nearly half of the world freshwater turtles threatened with extinction. Australia is high on the list of contributing countries, with one third of its native species threatened with extinction. The Murray River is an obvious example with populations of its native species Emydura macquarii declining by 69% and Chelodina longicollis declining by 91% over the past 30 years. Nest predation by the red fox and the installation of water regulators, which have affected dispersal a

Abstract:

Murray cod Maccullochella peelii peelii is an iconic freshwater angling species that has suffered declines in abundance and is now listed as a nationally vulnerable species. Despite recognition of the need for biological knowledge to provide future management directions, little is known of its ecology. This thesis examines that ecology to provide new knowledge and recommendations for improved conservation management. (For complete abstract open document)

Abstract:

The decline of floodplain vegetation along the Lower River Murray, South Australia, has evoked recommendations for ‘environmental flows’ to restore and maintain the health of the ecosystem. To assist managers to maximize benefits from environmental flows, this thesis considers the significance of water for germination and recruitment in key floodplain plant species. Three dominant species are considered, including two trees, river red gum (Eucalyptus camaldulensis) and black box (E. largiflorens), and an understorey shrub, tangled lignum (Muehlenbeckia florulenta). The soil seed bank was domin

Abstract:

Climatic conditions in recent decades have been characterised with more frequent, long-term, and severely adverse events (e.g. drought) occurring in many countries. Many studies have found a link between various climatic evens and their negative impact on societies’ health, wellbeing and work productivity. In particular, there has been an increasing focus in the literature on the link between mental health and climatic variability, especially for rural communities. This is especially so for farming communities in Australia’s Murray-Darling Basin (MDB). MDB farmers have experienced significant
