Coal Seam Methane

The coal seams of the coal basins in New South Wales contain vast resources of methane. The gas has been of interest in the past, principally because the inflow of significant quantities into coal mine workings is a danger to mine safety and reduces production. Drainage techniques have been introduced into deeper collieries but they have not proved to be totally effective.Surface pre-drainage operations using hydraulic fracturing to stimulate gas production have been successful in the United States over recent years. The technique has yet to be successfully tested in New South Wales but if effective it will enable future mining areas to be drained prior to commencement of mining. The technique will also enable commercial production of large quantities of methane from both within and outside the coal mining areas.Seven organisations have commenced or will soon commence the exploration and development of the State's coal seam methane resources. Total planned expenditure over the next two years is over $4 000 000. Other Australian and overseas organisations are actively reviewing investment opportunities.Detailed exploration programs will be required prior to the commencement of operations because of the relative lack of data on the geology and gas resources of the basins. Differences exist between Australian and American coals and comparative reservoir and pilot studies will be required to determine the most effective pre-drainage methods. Potential markets exist in the State for methane and changes have been made to relevant legislation and administrative procedures to create incentives for exploration and production. Careful land-use planning will be required to ensure that the gas resource is not sterilised.

Coal Seam Methane

Significant work is taking place in Queensland and New South Wales to make the recovery of natural gas from coal seams (Coal Seam Methane) a viable industry. At this stage there are still some daunting hurdles to overcome. Australian buyers and financiers remain sceptical on resource risk and continuity of supply issues. In the USA commercial production has been taking place for 20 years, but the industry was only able to achieve credibility and viability by relying on tax breaks. Unfortunately, the same type of government incentives are not present in Australia. Whether, in the absence of these incentives, Australian producers can harness the resource on an economic basis remains to be seen.

Soil Loss Equation

The Universal Soil Loss Equation (USLE) and its main derivate, the Revised Universal Soil Loss Equation (RUSLE), are widely used in estimating hillslope erosion. The effects of topography on hillslope erosion are estimated through the product of slope length (L) and slope steepness (S) subfactors, or LS factor, which often contains the highest detail and plays the most influential role in RUSLE. However, current LS maps in New South Wales (NSW) are either incomplete (e.g. point-based) or too coarse (e.g. 250 m), limiting RUSLE-based applications. The aim of this study was to develop automated procedures in a geographic information system (GIS) to estimate and map the LS factor across NSW. The method was based on RUSLE specifications and it incorporated a variable cutoff slope angle, which improves the detection of the beginning and end of each slope length. An overland-flow length algorithm for L subfactor calculation was applied through iterative slope-length cumulation and maximum downhill slope angle. Automated GIS scripts have been developed for LS factor calculation so that the only required input data are digital elevation models (DEMs). Hydrologically corrected DEMs were used for LS factor calculation on a catchment basis, then merged to form a seamless LS-factor digital map for NSW with a spatial resolution ~30 m (or 1 s). The modelled LS values were compared with the reference LS values, and the coefficient of efficiency reached 0.97. The high-resolution digital LS map produced is now being used along with other RUSLE factors in hillslope erosion modelling and land-use planning at local and regional scales across NSW.

AbstractThe minus 1μm fraction of an argillized vitric tuff, overlying the Wallarah Coal Seam near Swansea, N.S.W. is a nearly monomineralic (95%+) expandite clay, which hydrates and reacts to glycerol and heat treatments like montmorillonite. Results of X-ray, differential thermal, thermogravimetric and infrared absorption analyses confirm the general montmorillonoid character of the mineral, but chemical data indicate that much of its structure charge arises from substitutions in the tetrahedral zones of the lattice, as in beidellite rather than montmorillonite. The structural fOrmula deduced for the Ca++-saturated form of the minus 0.1μm clay is:The distinctive behaviours of the heat-treated NH4+- and Li+-saturated structures also suggest that the mineral is a 'beidellitic montmorillonite' rather than a montmorillonite.

The demands on governments and local authorities are changing in response to community expectations for environmentally sustainable outcomes. To reverse declining water quality in rivers and ensure sustainable use in the 21st century, the State Government in New South Wales has introduced a package of Water Reforms. The introduction of integrated water, sewerage and drainage planning is one of the Water Reform initiatives. Traditionally, government and local authorities have managed their water supply, sewerage and stormwater drainage systems as separate entities. Integrated urban water planning is a structured planning process to evaluate concurrently the opportunities to improve the management of water, sewerage and drainage services within an urban area in ways which are consistent with broader catchment and river management objectives. The New South Wales Department of Land & Water Conservation (DLWC) has developed an integrated urban water planning process through a number of recent pilot studies. The process links urban water management objectives to overall catchment and river management objectives. DLWC is currently developing a set of guidelines for integrated urban water plans. DLWC has developed the Integrated Urban Water Planning methodology through three pilot studies in the New South Wales towns of Finley, Goulburn and Bombala. The pilot studies have shown that an integrated approach to water, sewerage and stormwater planning can identify opportunities that are not apparent when separate strategies are developed for each service. The result is better-integrated, more sustainable solutions, and substantial cost savings for local communities.

The Regular Classroom Practices Survey (RCPS) was conducted to determine the extent to which gifted and talented students received differentiated education in the regular classroom across New South Wales. This research paralleled work recently completed in the United States of America. The survey focused on information on the teachers, their classrooms and regions. Classroom practices, in relation to the curriculum modifications for gifted and average students, were analyzed. The survey sample was drawn from the three sectors of education, Government, Catholic and Independent schools, within the ten regions of New South Wales. This included 401 third and fourth grade teachers in government schools, 138 teachers in Catholic schools and 67 teachers in independent schools. The research questions that guided this study were: (1) Do teachers modify the curriculum content to meet the needs of gifted students? (2) Do teachers modify their instructional practices for gifted students? (3) Are there any organizational variations in planning to meet the educational needs of gifted children? (4) Are there differences in the types of regular classroom services provided for gifted students in relation to the type of school or region?

The Cost

Abstract As in many other parts of the globe, migration to the coast and rapid regional development in Australia is resulting in large concentrations of population and insured assets. One of the most rapidly growing regions is southeastern Queensland and northern New South Wales, an area prone to flooding. This study reexamines the Great Flood of 1954 and develops a deterministic methodology to estimate the likely cost if a similar event had occurred in 2011. This cost is estimated using council flood maps, census information, historical observations, and Risk Frontiers' proprietary flood vulnerability functions. The 1954 flood arose from heavy rainfall caused by the passage of a tropical cyclone that made landfall on 20 February near the Queensland–New South Wales border, before heading south. Responsible for some of the largest floods on record for many northern New South Wales' river catchments, it occurred prior to the availability of reliable insurance statistics and the recent escalation in property values. The lower-bound estimate of the insurance loss using current exposure and assuming 100% insurance penetration for residential buildings and contents is AU$3.5 billion, a cost that would make it the third-highest ranked insured loss due to an extreme weather event since 1967. The corresponding normalized economic loss is AU$7.6 billion but the uncertainty about this figure is high. The magnitude of these losses reflects the accumulation of exposure on the floodplains. Risk-informed land-use planning practices and improved building regulations hold the key to reducing future losses.

Specific Identity

The nematode Trichostrongylus longispicularis was described by Gordon (1933) from a single male recovered from a sheep in New South Wales. Gordon considered that the male of this species could be readily distinguished from the males of other species of the genus recorded from ruminants by an asymmetrical dorsal ray of the bursa and by the length and form of the spicules. The dorsal ray is described as being bifid, one bifurcation being simple and the other possessing secondary branches, one situated internally and the other externally. The slender spicules were 184·6 microns long, and terminated in fine sickle-shaped structures.Andrews (1934 and 1935) recorded the species from cattle in the United States. In his first description (Andrews, 1934) he noted that his specimens agreed very closely with the description published by Gordon (1933), but he referred to hook-like projections on the spicules. However, he failed to find these projections in the specimen discussed in his record of 1935. As he made no reference to the dorsal ray of the bursa, it is presumed that this agreed with the description and figure published by Gordon (1933). T. longispicularis was subsequently reported by Roberts (1938 and 1939) from cattle in Queensland, but no comments were made on its morphology.

The Public Sphere

Chapter 4 presents an empirical case on the problematic public disconnect in contemporary democracy where multiple publics are fractured in the public sphere. The chapter explores how a group of everyday citizens created connections between diverse publics in the public sphere. The analysis centres on the creative and playful connective activities of Knitting Nannas Against Gas (KNAG), an Australian-based social protest group opposed to coal seam gas development. Drawing on interviews conducted with the members of these groups across four different locations in New South Wales, the chapter reveals a rich variety of ways in which these groups seek to create connections with two opposing publics, as well as with latent publics. The chapter shows the significance of aesthetic-affective forms of communication, including non-verbal communication in crafting novel connections in a fractured public sphere, and discusses the ways these connections can help enhance the epistemic quality and reflexivity of the public sphere. The chapter concludes by discussing how the case of KNAG enriches current ideas on connectivity in deliberative systems.
