Abstract (sommario):

Tom Stannage was one among many historians in the 1970s uncovering histories of Australia which were to challenge national narratives and community memories. In 1971, Tom returned to Western Australia after writing his PhD in Cambridge with the passion to write urban history and an understanding that in order to do so, he needed an emotional engagement with place. What he had yet to realize was the power of community memories in Western Australia to shape and preserve ideas about their place. As part of his research on the history of Perth, Tom saw how the written histories of Western Australia had been shaped by community mythologies – in particular that of the rural pioneer. He identified the consensus or ‘gentry tradition’ in Western Australian writing. In teasing out histories of conflict, he showed how the gentry tradition of rural pioneer histories silenced those of race and gender relations, convictism and poverty which were found in both rural and urban areas. His versions of history began to unsettle parts of the Perth community who found the ‘pioneer myth’ framed their consensus world-view and whose families were themselves the living links to these ‘pioneers’.

Abstract (sommario):

The evolution of urban form is a slow and complex process driven by various factors which influence its pattern of occurrence (time, shape and directions) over time. Given the ever-increasing demand for urban expansion, and its negative effects on travel efficiency and environmental quality, it is imperative to understand the driving forces behind this complex process. This study investigates the role played by transport developments in the expansion of Perth’s urban footprint. Since transport developments are influenced by prevailing economic developments and planning regulations, our analysis starts by deconstructing a timeline of milestones under these three themes, from an urban land development perspective. An overview of the eras of transport evolution is provided, and we discuss the pattern of urban form changes as they relate to these transport advancements. The paper ends by mapping and quantifying changes in Perth’s urban land over the past five decades. The results show that transport had a strong influence on the pattern of urban expansion for a long time, but that trend has now been reversed. Rail constructions have been playing catch-up to residential expansion since the late twentieth century. Meanwhile, the rate of urban expansion has gone down in the twenty-first century, as the city goes for compact growth.

Abstract (sommario):

Birds in urban landscapes must contend with fragmented and degraded remnants of native vegetation and their survival may be dependent on factors such as their ability to disperse through and/or utilize the urban matrix. We examined the frequency of occurrence of birds in native bushland in Kings Park, Perth, Western Australia, and in nine adjacent suburban gardens. We quantified dispersal capacity by observing bird crossing frequency and height over a major six-lane road separating the bushland from adjacent gardens. Finally we quantified matrix utilisation by recording foraging behaviour in urban gardens and bushland. Native bushland had a higher species richness than urban gardens (30 versus 17 species) and 18 species were associated more strongly with bushland. Of these 18 species, 61% were never recorded in urban gardens. Gardens were typified by three generalist species, the Singing Honeyeater Lichenostomus virescens and the introduced Laughing Dove Spilopelia senegalensis and Spotted Dove S. chinensis. Three generalist species, the Red Wattlebird Anthochaera carunculata, Rainbow Lorikeet Trichoglossus haematodus, and Brown Honeyeater Lichmera indistincta were equally abundant in all habitats. Four of 18 bird species (Singing Honeyeater Red Wattlebird, Rainbow Lorikeet, and Australian Ringneck Barnardius zonarius) accounted for the majority of road crossing events. Urban gardens provided a rich resource for generalists and urban exploiters, all of which spent significantly more time foraging on nectar in gardens and significantly more time foraging on insects in bushland. We conclude that urban gardens provide habitat for some species that exploit nectar, but most species in bushland, particularly insectivores, do not use gardens. Our results indicate the importance of retaining well-managed bushland for supporting viable urban bird populations.

Abstract (sommario):

The struggle to save the Beeliar Wetlands, an urban remnant bushland in Perth, Western Australia, demonstrates elements of both urban social and urban environmental movements. At the end of 2016, 30 years of objection to the continuation of the Roe Highway development (Roe 8) culminated in months of intense protest leading up to a state election and a cessation of work in 2017. During the long-running campaign, protestors fought to preserve high-conservation-value bushland that was contained in the planned road reserve. At the heart of this dispute were competing spatial uses. This article will analyze four protest actions from the dispute using Henri Lefebvre’s concept of the production of space, and will demonstrate that the practices of protest gave those fighting to preserve Roe 8 the agency to reinscribe meaning to the natural uses of the Beeliar Wetlands over and against the uses privileged by the state.

Abstract (sommario):

The widely applied Importance-Performance Analysis (IPA) provides relatively simple and straightforward techniques to assess how well the attributes of a good or service perform in meeting the expectations of consumers, clients, users, and visitors. Surprisingly, IPA has rarely been applied to inform the management of urban public green infrastructure (PGI) or urban nature (UN) spaces. This case study explores the visitor satisfaction levels of people using a PGI space that incorporates UN, close to the central business district of Perth, Western Australia. With diminishing opportunities to acquire new PGI spaces within ever more densely populated urban centers, understanding, efficiently managing, and continuously improving existing spaces is crucial to accessing the benefits and services that PGI and UN provide for humankind. An intercept survey conducted within the Lake Claremont PGI space utilized a self-report questionnaire to gather qualitative and quantitative data (n = 393). This case study demonstrates how the IPA tool can assist urban planners and land managers to collect information about the attributes of quality PGI and UN spaces to monitor levels of service, to increase overall efficiency of site management, to inform future management decisions, and to optimize the allocation of scarce resources. The satisfaction of PGI users was analyzed using the IPA tool to determine where performance and/or resourcing of PGI attributes were not congruent with the expectations of PGI users (generally in the form of over-servicing or under-servicing). The IPA demonstrated that a majority of PGI users perceived the study site to be high performing and were satisfied with many of the assessed attributes. The survey identified the potential for some improvement of the amenity and/or infrastructure installations at the site, as well as directing attention towards a more effective utilization of scarce resources. Optimizing the management of PGI spaces will enhance opportunities for individuals to obtain the physiological, psychological, and emotional benefits that arise from experiencing quality urban PGI spaces. This case study promotes the important contribution that high-quality PGI spaces, which include remnant and restored UN spaces, make to the development of resilient and sustainable urban centers.

Abstract (sommario):

The Gnangara Mound is an area of elevated sandy soil on the Swan Coastal Plain to the north of Perth. It constitutes a major groundwater resource for metropolitan Perth. Sixteen wetlands on the Mound had total phosphorus concentrations of 12-462�g L-1, the high values being attributed to agricultural and urban activity. Sediment concentrations of total phosphorus and total nitrogen were 61-954 and 1212-16739 �g g-1, respectively. Conductivities were 505-10270 �S cm-1, and pH values were 3.3-9.3. Only one wetland was highly coloured (79.9 8440 m-1), with an E4/E6 ratio of 4.6. Chlorophyll a concentrations were 0.01-130.8�g L-1; in wetlands with low gilvin concentrations, Myxophyceae dominated, whereas wetlands with higher gilvin concentrations had large numbers of diatoms and Chlorophyceae. The highly coloured wetland had the lowest chlorophyll a concentration despite high nutrient concentrations, supporting the hypothesis that the consequent reduction in light or other associated factors are important in maintaining low phytoplankton biomass in dystrophic wetlands of the region, particularly those on Bassendean sands.

Abstract (sommario):

A decline in the watertable due to a long period of low rainfall, and the disturbance of sulfidic peat soils by dewatering and excavation in the Perth suburb of Stirling, has led to widespread acidification of groundwater at the watertable in a residential area and contamination of groundwater by arsenic and metals. The acidification has been caused by the oxidation of sulfide minerals within the peat, which contains up to 15% by weight of oxidiseable sulfur. Groundwater of pH 1.9 has been measured in shallow monitoring bores in the area, as well as high arsenic (up to 7 mg/L), aluminium (up to 290 mg/L), and iron (up to 1300 mg/L) concentrations. Contaminated groundwater pumped from affected domestic garden bores caused plant deaths in gardens and has given rise to health concerns because of high arsenic and metal concentrations. Drilling has indicated that acidic groundwater generally extends 5–10 m below the watertable, and that deeper groundwater is currently unaffected by contamination. As groundwater forms 70% of Perth’s total water usage and sulfide-rich peat soils are common in the region, acid sulfate soil risk maps and management policies need to be developed and implemented as a matter of urgency to prevent similar acidity problems occurring elsewhere in Perth.

Abstract (sommario):

AbstractAs a musical form, punk is often associated with urbanity, as embodied in the scenes in both London and New York, and in an Australian national context by the scenes in Melbourne and Sydney. In Perth, Western Australia – a primarily middle-class suburban city without a distinct inner city – punk was expressed differently. While the music itself exemplified many of the stylistic traits associated with the genre, punk in Perth was articulated through the city's isolation, its affluence and its suburban nature. Utilising interviews with key players in the Perth punk scene of the late 1970s, this paper seeks to illustrate the ways in which urbanity was constructed and voiced through Perth punk, in a city that constructed itself in opposition to traditional notions of the inner city's urban lived environment.

Abstract (sommario):

The Noongar Aboriginal people are the traditional owners of the southwest of Western Australia, including the land on which the city of Perth is located. Their recent history has been dominated by brutal and racist government policies that have created a diverse and complex community working to rediscover and preserve Noongar culture. Community media can be an effective and empowering tool for preserving culture, shaping a contemporary Noongar identity and creating a dialogue between the Indigenous and non-Indigenous urban community of Perth. This article discusses issues of Noongar identity in Perth, and looks at how lessons from the past are shaping new Noongar media initiatives and the establishment of Noongar radio.

Testo completo

Abstract (sommario):

The 71 reptile species occurring in the Perth region make this area as diverse as any similar sized coastal region in Australia. Cluster analysis of the lizard assemblages of 17 bushland remnants in the region indicate that three main sub-regions can be identified; Darling Plateau and Scarp, Offshore Islands and Swan Coastal Plain. Within the Swan Coastal Plain the lizard and skink faunas of remnant bushlands on the same landform are more similar to one another than they are to those of adjacent landforms. The Swan River appears to be a distributional boundary for some species. Species-area relationships indicate a variety of responses amongst the different taxonomic groups of reptiles, with snakes being the most sensitive to loss of habitat. The isolated remnant bushlands of inner urban areas retain a variety of reptile species, but there is no significant relationship with remnant size. The implications of zoogeographic and area relationships to conservation are discussed.

Abstract (sommario):

Public recreation areas in cities may be constructed on land which has been contaminated by various processes over the history of urbanisation. Charles Veryard and Smith’s Lake Reserves are adjacent parklands in Perth, Western Australia with a history of horticulture, waste disposal and other potential sources of contamination. Surface soil and soil profiles in the Reserves were sampled systematically and analysed for multiple major and trace elements. Spatial analysis was performed using interpolation and Local Moran’s I to define geochemical zones which were confirmed by means comparison and principal components analyses. The degree of contamination of surface soil in the Reserves with As, Cr, Cu, Ni, Pb, and Zn was low. Greater concentrations of As, Cu, Pb, and Zn were present at depth in some soil profiles, probably related to historical waste disposal in the Reserves. The results show distinct advantages to using spatial statistics at the site investigation scale, and for measuring multiple elements not just potential contaminants.

Testo completo

Abstract (sommario):

Vegetation trampling that arises from off-trail excursions by people walking for recreation can negatively impact the structure of understory plants in natural spaces that are an essential element of urban green infrastructure in a modern city. In addition to reducing the esthetic quality and environmental values of urban remnant and replanted native vegetation, such trampling reduces the habitat that supports wildlife populations within the urban fabric. This case study draws upon several disparate methods for measuring vegetation structure and trampling impacts to produce a hybrid method that community-based citizen scientists (and land managers and other researchers) could use to simply, rapidly, and reproducibly monitor how trampling associated with urban recreation trails impacts the structure of understory vegetation. Applying the novel hybrid method provided evidence that trampling had reduced the vegetation structure adjacent to a recreational walking trail in an urban woodland remnant in Perth, Western Australia. The hybrid method also detected ecological variability at the local ecosystem-scale at a second similar woodland remnant in Perth. The hybrid sampling method utilized in this case study provides an effective, efficient, and reproducible data collection method that can be applied to recreation ecology research into aspects of trampling associated with trail infrastructure.

Abstract (sommario):

North Lake is an urban freshwater wetland, and like other wetlands in the Perth metropolitan region, Western Australia, has become nutrient enriched, with the accompanying problems of algal blooms, decay, odour, infestation with midges and aesthetic deterioration. A study of the water quality of the lake was undertaken to quantify the variation of phosphorus, nitrogen and chlorophyll-a, and the sediments store of nutrients and their release with pH. The dominant algae in the lake, Microcystis, was found to be limited in growth by nitrogen because of the high availability of phosphorus (> 0.1 mg/l), and likely by light because of self-shading (chlorophyll-a > 0.3 mg/l). Sediments released a substantial amount of nutrients as pH rose above 8.5. Together with a parallel study of the nutrient budget of the lake, a management strategy has been derived to overcome the problem of nutrient enrichment that could be applied to other wetlands in the metropolitan region.

AbstractThere is a paucity of published information about conceptions of Aboriginal child rearing and development among urban dwelling Nyoongar/Aboriginal people in Australia. We detail the unique findings from an Aboriginal early child development research project with a specific focus on the Nyoongar/Aboriginal community of Perth, Western Australia. This research significantly expands the understanding of a shared system of beliefs and values among Nyoongar people that differ in important ways from those of the broader Australian (Western) society. Consistent with the findings of research with other Aboriginal groups in Australia, and internationally, our work challenges assumptions underpinning a range of early childhood development policies and highlights the implications of cultural biases and misunderstandings among non-Aboriginal professionals in child and family services, education and other settings.

The mean size of activity area was 8.91 ha; activity area was positively correlated with body size. There were significant overlaps in activity areas and no evidence of territoriality for male or female V. gouldii. The animals often foraged in areas of dense leaf litter near the periphery of their activity area and retreated to burrows that were more centrally located.

Abstract (sommario):

AbstractThis paper presents an analysis of the classroom discourse and strategies of Marcia, an early childhood teacher of a class with a high percentage of Indigenous Australian students. These students have been demonstrably successful on standardised literacy tests, which is not the case for Indigenous students in general in Australia (e.g., MCEETYA, 200). It will be suggested here that Marcia’s approach and relationships with the students, as constructed in her discourse, have been a large contributing factor in this success. Marcia’s discourse can be described as both inclusive and empowering and, as such, it will be proposed that awareness of her techniques may be of benefit to teachers who are working with groups whom education systems tend to marginalise and disempower. Marcia’s lessons were observed as part of the project, “Teaching Indigenous Students with Conductive Hearing Loss in Remote and Urban Schools of Western Australia”. This project was based in Kurongkurl Katitjin, School of Indigenous Studies, at Edith Cowan University, Perth, Western Australia, and was funded by an Australian Research Council Strategic Partnerships with Industry [SPIRT] Grant and the industry partners: Department of Education of Western Australia, Catholic Education Commission of Western Australia and Aboriginal Independent Community Schools, Western Australia.

Abstract (sommario):

Trees in urban settings are becoming increasingly important as mediators to emerging challenges that transect social, environmental, and economic factors. Trees provide shade; absorb and store atmospheric carbon and other pollutants; reduce local temperature fluctuations; provide essential inner-city fauna habitat; assist in reducing over-land stormwater flow; provide amenity; and provide many more social, environmental, and economic benefits. To secure these benefits, tree canopy cover targets are commonly employed by land managers; however, such targets are rarely quantified against the characteristics and limitations of individual urban centers. Through the generation and interrogation of qualitative and quantitative data, this case study of Perth, Western Australia presents a new conceptual tool that integrates eleven factors found to influence the capacity and opportunity for a city to support urban tree canopy cover. This tool is designed to capture and causally weigh urban tree canopy considerations based on individual city characteristics, collective values, and identifiable constraints. The output of the tool provides an “optimum” tree canopy cover result (as a percentage of the urban fabric) to better inform canopy cover targets and recommendations for urban tree strategic planning and management. This tool is valuable for urban land managers, city planners, urban designers, and communities in effective planning, management, valuation, and investment regarding urban trees as a sub-set of urban green infrastructure.

Abstract (sommario):

The Western Australia Department for Planning and Infrastructure has initiated a unique information provision program to decrease the use of cars and increase nonmotorized transport. The program contains a component in South Perth that uses individualized marketing techniques to inform travelers about alternatives to the private automobile. Data about this program have been collected in the past 3 years, offering the opportunity to assess the program’s success. Regression analysis has been used to estimate the effect of information provision on program participants’ travel behavior for mobility and, more specifically, mode choice. Program participants, persons who agree to receive and use information, when compared with a variety of other groups consistently use the car as driver the least and appear to have increased their nonmotorized trip making. The findings here are extremely encouraging, and programs like this should be considered in other urban settings.

Abstract (sommario):

Urban remnant vegetation is subject to varying degrees of disturbance that may or may not be proportional to the size of the patch. The impact of disturbance within patches on species with low mobility and dispersal capabilities was investigated in a survey targeting nemesiid species of the mygalomorph spider clade in the Perth metropolitan area, south-western Australia. Nemesiid presence was not influenced by patch size, but presence did negatively correlate with higher degrees of invasive grass and rabbit disturbance. Further, patch size was significantly positively correlated with degree of disturbance caused by rabbits. Compared with quadrats, patches were not as effective as sample units in determining the impact of disturbance on nemesiid presence.

Abstract (sommario):

This Data Descriptor shares the dataset generated by a visitor satisfaction survey of users of a mixed-use public green infrastructure (PGI) space in Perth, Western Australia, that incorporates remnant and reintroduced urban nature (UN). Conducted in the Austral summer of 2016–2017, the survey (n = 393) utilized the technique of Importance-Performance Analysis (IPA) to elucidate perceptions of PGI users regarding performance of the amenity and facilities at the study site. There is a growing body of research that reports the innate, inbuilt affinity of humans to natural systems and living things. As humankind has grown exponentially over the past 50 years, humanity, as a species, is living an increasingly urbanized lifestyle, resulting in spreading urban footprints and increased population densities that are causing humans to become increasingly disconnected from nature. These conflicting phenomena are driving research to understand the contribution that PGI and UN can make to enhancing the quality of life of urban residents. With diminishing opportunities to acquire or create new PGI spaces within ever-more-densely populated urban centers, understanding, efficiently managing, and continuously improving existing PGI spaces is crucial to access the benefits and services that PGI and UN provide. The IPA technique can provide the data necessary to inform an evidenced-based approach to managing and resourcing PGI and UN spaces.

Abstract (sommario):

The level of commuting in cities is an important indicator of the efficiency of urban spatial structure. Recent research has come out in support of land use policies that promote balancing the number of employment opportunities and residents in local geographical units to reduce excess commuting. This study explores three employment self-sufficiency indices: job-worker balance (JWB), employment self-sufficiency (ESS) and employment self-containment (ESC), as measures for reducing the level of commuting. Using the case of Perth, Western Australia, we perform a trip-based evaluation of these three variables and investigate their effect on commuting time through statistical correlation. The results reveal that JWB, ESS and ESC levels are relatively poor across the metropolitan region. Higher ESS correlates with lower inflow travel time, but better JWB and higher ESC do not necessarily lead to shorter travel times. The findings of this study suggest that policies solely relying on these measures may not be effective in reducing commuting times. ESS and ESC do not account for the component of the trip outside the zone, which can misrepresent the level of commuting in an area. Incorporating travel time in these measures can complement their reliability, and better represent overall commuting levels within an urban structure.

Abstract (sommario):

Purpose – The purpose of this paper is to ascertain the level of social capital in environmental community organisations (ECOs) in Perth, Western Australia. On a general level, social capital in ECOs is understood as intra-organisational and inter-organisational relationships that organisations maintain through interactions. Design/methodology/approach – This paper utilises quantitative (i.e. survey) as well as qualitative (i.e. interviews) approaches to data collection and analysis. It proposes a methodological framework to measure the level of social capital, and explores the association between the ascertained level of social capital and organisational capabilities. Findings – The results of the survey and interviews reveal that while the level of social capital is needs based, maintaining a higher intensity of organisational relationships puts ECOs in a better position to do more with less. Research limitations/implications – The findings advance the task of ascertaining the level of social capital in ECOs from organisational interactions perspective. Originality/value – This paper captures a community organisation-specific methodological framework to measure and analyse social capital.

Abstract (sommario):

An incursion of the African Big-headed Ant, Pheidole megacephala, has recently been recorded in bushland in Perth, Western Australia. This unexpected discovery prompted an investigation into the effects of the incursion on the native ant assemblages. Extensive pitfall trapping in invaded and non-invaded areas revealed that the incursion had a significant negative impact on ant species richness, diversity and evenness. Approximately 53% of native ant species present in non-invaded bushland were not sampled in areas occupied by P. megacephala, while the remaining species suffered considerable declines in frequency of occurrence. Many of these species perform important ecosystem functions, and their loss was thought to have had serious consequences on the ecosystem. Changes to the prevalence of the various ant Functional Groups indicated major disruptions to the composition of the assemblage as the abundance of P. megacephala increased. Ants that avoided direct competition with P. megacephala, by occupying temperature dependant temporal niches, were more persistent in its presence. Estimates of the ant biomass sampled indicated that the invasive population was larger than that of all other ant species combined by several orders of magnitude. A feeding trial revealed intensified exploitation of food resources in invaded areas, which could have flow-on effects on other invertebrates and plants. Changes to predation, decomposition, and soil amelioration regimes, as well as possible disruptions to ant-plant interactions and invertebrate symbioses resulting from the disappearance of native ant species, were thought to have further eroded the conservation values of the ecosystem.

Abstract (sommario):

Bluetooth (BT) time-stamped media access control (MAC) address data have been used for traffic studies worldwide. Although Bluetooth (BT) technology has been widely recognised as an effective, low-cost traffic data source in freeway traffic contexts, it is still unclear whether BT technology can provide accurate travel time (TT) information in complex urban traffic environments. Therefore, this empirical study aims to systematically evaluate the accuracy of BT travel time estimates in urban arterial contexts. There are two major hurdles to deriving accurate TT information for arterial roads: the multiple detection problem and noise in BT estimates. To date, they have not been fully investigated, nor have well-accepted solutions been found. Using approximately two million records of BT time-stamped MAC address data from twenty weekdays, this study uses five different BT TT-matching methods to investigate and quantify the impact of multiple detection problems and the noise in BT TT estimates on the accuracy of average BT travel times. Our work shows that accurate Bluetooth-based travel time information on signalised arterial roads can be derived if an appropriate matching method can be selected to smooth out the remaining noise in the filtered travel time estimates. Overall, average-to-average and last-to-last matching methods are best for long (>1 km) and short (≤1 km) signalised arterial road segments, respectively. Furthermore, our results show that the differences between BT and ground truth average TTs or speeds are systematic, and adding a calibration is a pragmatic method to correct inaccurate BT average TTs or speeds. The results of this research can help researchers and road operators to better understand BT technology for TT analysis and consequently to optimise the deployment location and configuration of BT MAC address scanners.

Abstract (sommario):

Wild brushtail possums (Trichosurus vulpecula) occur in large numbers in the grounds of Perth Zoo, Western Australia. These possums are a problem because they consume feed the zoo buys for its captive animals, damage seedlings and trees and many need to be treated for injuries sustained during fights with conspecifics. A contraceptive implant, which contains the gonadotrophin releasing hormone (GnRH) agonist deslorelin, could be a potential method of managing this population. We tested the efficacy of the implant and its impact on the body-condition index of treated possums with Kaplan–Meier analysis and a mixed model with residual maximum likelihood. We implanted 60 female possums with deslorelin and monitored reproductive success of treated and untreated possums for the following 18 months. At the conclusion of the study, 80% of 20 treated females recaptured had shown no evidence of breeding activity, giving an average minimum duration of effective contraception of 381 days. The implant did not have a negative impact on the body-condition index of treated possums during the course of the study. Our results suggest that deslorelin implants could be an effective management tool for brushtail possums at Perth Zoo and in other urban environments.

Abstract (sommario):

Urban water systems will be increasingly challenged under future climates and global pressures. Meeting challenges by reconfiguring water systems to integrate supplies and deliver multifunctional uses is technically well described. Adjusting the institutions that frame the management of these systems is not well operationalized in practice or conceptualized in theory. This study seeks to address this gap through an institutional analysis of Perth, Australia, a city where drought crisis has put under pressure both management practices and the institutional setting that underlies them. The study found that while trusted practices moderated water scarcity, the stability of the institutional setting may not facilitate a shift toward adaptable institutional configurations suited to future conditions. The results identified three key ingredients for a flexible institutional setting: (i) feedbacks in the system through better information management, (ii) reflexive dialogue and strategic use of projects to generate greater learning opportunities, and (iii) policy level support for sector-wide collaboration through progressive agendas, incentives for innovation and capacity building in stakeholder and community engagement. Further, the results suggest that a deeper understanding of institutional dynamics is needed to enable adaptive governance. The paper provides an analytical framework for diagnosing how greater adaptive capacity might be mobilized through influencing these dynamics.

Abstract (sommario):

Abstract. The groundwater resource contained within the sandy aquifers of the Swan Coastal Plain, south west Western Australia, provides approximately 60% of the drinking water for the metropolitan population of Perth. Rainfall decline over the past three decades coupled with increasing water demand from a growing population has resulted in falling dam storage and groundwater levels. Projected future changes in climate across south-west Western Australia consistently show a decline in annual rainfall of between 5 and 15%. There is expected to be a continuing reduction of diffuse recharge across the Swan Coastal Plain. This study aims to quantify the change in groundwater recharge in response to a range of future climate and land cover patterns across south-west Western Australia. Modelling the impact on the groundwater resource of potential climate change was achieved with a dynamically linked unsaturated/saturated groundwater model. A Vertical Flux Manager was used in the unsaturated zone to estimate groundwater recharge using a variety of simple and complex models based on land cover type (e.g. native trees, plantation, cropping, urban, wetland), soil type, and taking into account the groundwater depth. These recharge estimates were accumulated on a daily basis for both observed and projected climate scenarios and used in a MODFLOW simulation with monthly stress periods. In the area centred on the city of Perth, Western Australia, the patterns of recharge change and groundwater level change are not consistent spatially, or consistently downward. In the Dandaragan Plateau to the north-east of Perth there has been groundwater level rise since the 1970s associated with land clearing, and with rainfall projected to reduce the least in this area the groundwater levels are estimated to continue to rise. Along the coastal zone north of Perth there is an interaction between projected rainfall decline and legislated removal to pine forests. This results in areas of increasing recharge and rising water levels into the future despite a drying climate signal. To the south of Perth city there are large areas where groundwater levels are close to the land surface and not expected to change more than 1m upward or downward over the next two decades; it is beyond the accuracy of the model to conclude any definite trend. In the south western part of the study area, the patterns of groundwater recharge are dictated primarily by soil, geology and land cover. In the sandy Swan (northern boundary) and Scott Coastal Plains (southern boundary) there is little response to future climates, because groundwater levels are shallow and much rainfall is rejected recharge. The profile dries out more in summer but this allows more rainfall to infiltrate in winter. Until winter recharge is insufficient to refill the aquifers these areas will not experience significant falls in groundwater levels. On the Blackwood Plateau however, the combination of native vegetation and clayey surface soils that restrict possible infiltration and recharge mean the area is very sensitive to climate change. With low capacity for recharge and low storage in the aquifers, small reductions in recharge can lead to large reductions in groundwater levels. In the northern part of the study area both climate and land cover strongly influence recharge rates. Recharge under native vegetation is minimal and is relatively higher where grazing and pasture systems have been introduced after clearing of native vegetation. In some areas the low recharge values can be reduced to almost zero, even under dryland agriculture, if the future climate becomes very dry. In the Albany Area the groundwater resource is already over allocated, and the combination of existing permanent native vegetation with decreasing annual rainfall indicate reduced recharge. The area requires a reduction in groundwater abstraction to maintain the sustainability of the existing resource.

Abstract (sommario):

The foraging areas of Varanus gouldii were monitored by the spool-and-line technique over 51 consecutive days during October and November 1990 in Karrakatta Cemetery, Perth, Western Australia. The daily distance travelled by lizards varied markedly. The mean distance travelled was 111 -6m for days that varanids moved from their burrows. There was a weak positive correlation between the daily distance travelled and the maximum daily temperature and hours of daily sunshine. Some varanids moved their foraging areas from open unshaded sections of the cemetery into a more heavily treed area in November. The size of the daily foraging area for small varanids (<600g) was extremely variable (estimated median 300m*2); areas were greater in November than October. Some varanids moved to different foraging areas every few days.

Abstract (sommario):

SUMMARY Ambient wavefield data acquired on existing (so-called ‘dark fibre’) optical fibre networks using distributed acoustic sensing (DAS) interrogators allow users to conduct a wide range of subsurface imaging and inversion experiments. In particular, recorded low-frequency (<2 Hz) surface-wave information holds the promise of providing constraints on the shear-wave velocity (VS) to depths exceeding 0.5 km. However, surface-wave analysis can be made challenging by a number of acquisition factors that affect the amplitudes of measured DAS waveforms. To illustrate these sensitivity challenges, we present a low-frequency ambient wavefield investigation using a DAS data set acquired on a crooked-line optical fibre array deployed in suburban Perth, Western Australia. We record storm-induced microseism energy generated at the nearby Indian Ocean shelf break and/or coastline in a low-frequency band (0.04−1.80 Hz) and generate high-quality virtual shot gathers (VSGs) through cross-correlation and cross-coherence interferometric analyses. The resulting VSG volumes clearly exhibit surface wave energy, though with significant along-line amplitude variations that are due to the combined effects of ambient source directivity, crooked-line acquisition geometry and the applied gauge length, fibre coupling, among other factors. We transform the observed VSGs into dispersion images using two different methods: phase shift and high-resolution linear Radon transform. These dispersion images are then used to estimate 1-D near-surface VS models using multichannel analysis of surface waves (MASW), which involves picking and inverting the estimated Rayleigh-wave dispersion curves using the particle-swarm optimization global optimization algorithm. The MASW inversion results, combined with nearby deep borehole information and 2-D elastic finite-difference modeling, show that low-frequency ambient DAS data constrain the VS model, including a low-velocity channel, to at least 0.5 km depth. Thus, this case study illustrates the potential of using DAS technology as a tool for undertaking large-scale surface wave analysis in urban geophysical and geotechnical investigations to depths exceeding 0.5 km.
