Low flow hydrology: application of a systems approach

Nathan, Roderic John Unknown Date (has links) (PDF)
Australia is not only the driest continent, but its streams are among the most variable in the world. To date in Australia there has been no large-scale study of Australia’s low flow hydrologic characteristics, and consequently there is a fundamental need to develop methods that can be readily used to assess the hydrology during times of low flow. This thesis describes the development and derivation of a methodology for the estimation of low flow characteristics and yield in small ungauged rural catchments. The methodology has been applied to 184 catchments located in New South Wales and Victoria, in south-eastern Australia. A systems approach was adopted in which multivariate techniques were used to develop relationships between low flow parameters and climatic and land information data. The low flow and yield parameters considered include: descriptive statistics of monthly and annual flows, ratio of baseflow to total streamflow volumes, streamflow recession constants, flow duration curves for daily, monthly and annual durations, low flow frequency curves for durations from 1 to 284 days, duration of low flow spells below a given threshold, deficiency volume of low flow spells below a given threshold, estimate of storage to satisfy a specified draft at a given level of reliability, and parameters of a simple rainfall-runoff model for conversion of daily rainfall to monthly streamflow volumes.

Some aspects of the development of the metal trades in Ballarat 1851-1901

Cope, Graeme Stuart Unknown Date (has links) (PDF)
This thesis is an attempt to provide a special examination centering on some aspects on the development of metal processing and fabricating industries in the Victorian gold mining town of Ballarat from its foundation in 1851 to the end of its first half century in 1901. It is in effect a case study of a particular group of manufacturing activities made with the intention of improving general historians' understanding of the forces behind the establishment and growth of secondary industries in the non-metropolitan towns of nineteenth century Australia.

Pious tales and dirty stories : the Young Australians Best Book Award (YABBA)

La Marca, Susan Gaye January 1995 (has links)
A study of the older readers' section of Young Australians Best Book Award (YABBA) from 1986 to 1991, based on analysis of 21,351 voting forms from this period. Through analysis of the data from these voting forms, ranking authors and titles, comparing gender preferences, the source of the book voted for, school type and school location were all compiled into graphs and tables. Appropriate comparisons have been made between variables across the six year period, to give some idea of the voting population involved in the older readers' section of YABBA and their preferences and motivations. A follow up survey of voters and YABBA organisers in 1992 attempted to further enhance this data by collecting information on voter preferences, opinions and possible influences on the voting process. The study attempts to place YABBA in the context of the wider children's literature community and discuss briefly its historical development with reference to other children's choice awards, their strengths and weaknesses. A relevant discussion on popularity versus literary merit is related to the ongoing discussion of YABBA in comparison to the Children's Book Council awards. Later chapters include a discussion of the most popular YABBA titles (seven highest rating titles) with particular emphasis given to YABBA's two most popular authors - Paul Jennings and Robin Klein. Humour is an important factor in the popularity of many YABBA titles and this is discussed as are developments since 1991 and the long-term future of YABBA.

Legalisation of the sex industry in the State of Victoria, Australia: the impact of prostitution law reform on the working and private lives of women in the legal Victorian sex industry

Arnot, Alison Unknown Date (has links) (PDF)
In 1984 the State Parliament of Victoria began the process of legalising sectors of the Victorian sex industry. Reforming legislation was enacted in 1984, 1986 and 1994. To date there has been no research assessing the changes to the industry that have occurred as a result of the legalisation process, and in particular, the effect it has had on the lives of the women working in the industry. / This research has examined the impact of sex industry law reform on the working and private lives of women in the Victorian sex industry. Interviews were conducted with twenty women, nine of whom had worked in the industry prior to legalisation. All but four of the interviewees had experienced work in the industry before and after reforms. / A number of significant findings were made. Since legalisation brothels have become cleaner and physical surroundings have been improved. However, the owners and managers of industry businesses have increased their level of control over workers by determining services to be offered, fees to be charged and clothes to be worn.

An investigation of the factors and processes that influence the distribution of hydropsid caddisfly larvae in upland streams in southeastern Australia

Sharpe, Andrew Kenneth Unknown Date (has links) (PDF)
Stream ecology is dominated by studies that describe the distribution of invertebrate populations and communities. Many of these studies make untested assumptions about the various ecological processes that influence these distributions. The most common assumption, which is often unstated, is that distribution patterns reflect habitat selection by individual animals. However, very few studies have directly tested the relative importance of this process or considered other processes that may also affect the distribution of stream invertebrates. In this thesis I use a correlative survey in combination with manipulative field experiments and behavioural observations to investigate the factors and ecological processes that are associated with the distribution of hydropsychid caddisfly larvae in rocky upland streams in southeastern Australia.

The Australian Railways Union: railway management and railway work in Victoria 1920-1939

Churchward, Alison Ruth January 1989 (has links) (PDF)
This thesis takes the Australian Railways Union as a focus for an examination of the Victorian Railways between the two World Wars. The development of the union is traced through the optimistic expectations of the early 1920s, the disillusionment which followed the union’s affiliation with the ALP and registration under the Commonwealth Arbitration Court, to the increasing polarisation of the union on political lines as the 1930s progressed. At the same time the union’s relations with, railway management are explored. / The innovative management style of Harold Winthrop Clapp, whose term as Chief Railways Commissioner covered the two decades under discussion in this thesis, is examined and set in the context of developments elsewhere in Australia and overseas. The repercussions of Clapp’s administrative and technological changes in railway work are discussed throughout the thesis, and particular attention is paid to the relationship between such changes and job loss. The problems arising from lack of clarity over control of the Railways Department, which are also examined in a separate chapter, were common to other statutory authorities as well. The financial situation of the railways is discussed in relation to that of other Australian railways. The problem of transport regulation to prevent uneconomic competition between motor transport and railways, which received growing recognition during the period of this thesis, also receives special attention. / During the Great Depression, the Victorian Railways Department and the ARU played a central role in the national arena. The railway basic wage case of 1930, which resulted in a ten per cent cut in wages, set a precedent for all major industries. The analysis of transcripts of this lengthy case has produced much which is of general significance for economic and labour history. / In the final chapters of the thesis, the ARU is shown approaching the radicalism of the 1940s, when large scale industrial action was carried out under Communist leadership. The union in 1939, following two decades of activity as part of a federal railways union, and experience of arbitration and affiliation to the ALP, was very different from the union which had existed up until 1920 in Victoria, with its narrow sphere of activity bounded by ‘the railway fence’, and this thesis explores that transition.

Changes in soil physical properties under raised bed cropping

Holland, Jonathan Eddison Unknown Date (has links) (PDF)
Winter cropping often does not realise its full potential in south-western Victoria, where waterlogging is a major problem on the poorly drained soils of conventional cultivation (CC) systems. Consequently, cropping has been undertaken on raised beds (RB) to reduce the risk of waterlogging. Initial reports on the yields of RB were encouraging. It was hypothesized that an improvement in soil properties of RB may account for their better performance compared to CC systems. / The aim of the thesis was to evaluate selected soil physical properties of RB and to make comparisons with other treatments (CC and pasture). The specific objectives were to: 1) evaluate plant growth and crop yield; 2) quantify soil water dynamics; 3) assess changes in the soil water retention characteristic (SWRC), soil strength and soil hydraulic properties; 4) describe pore pathways from solute transport; and 5) quantify soil macropore structure. / Measurements of volumetric water content (θv) were taken at 20, 40, 60 and 80 cm and at the soil surface. These data allowed the determination of the profile soil water deficit (SWD), which was found to be greater under the RB than the CC, although at times the pasture had the largest SWD. The RB mostly remained drier than the CC, but the response to rainfall in the surface θv was similar between treatments. Below average rainfall was received during the whole study period which resulted in drier than normal conditions. / There was no consistent difference in plant growth between crops on the RB and CC; e.g. in 2004 periods of waterlogging resulted in greater dry matter production on the RB; while drier conditions in 2003 saw better crop growth on the CC. Grain yield varied annually according to rainfall, and overall the treatment yields were similar. Analysis of regional yield data showed that there was no yield difference in years with average or below average rainfall, but years with higher rainfall favoured RB. / Little difference was found in the laboratory-derived SWRC, but in the field the RB were consistently drier at all depths and at 60 cm depth the CC had a saturated zone. The RB were found to have a lower soil strength characteristic within the surface 24 cm compared to the CC. The air-filled porosity (AFP) was higher in the RB while for long periods the CC were <10 per cent AFP. There was no significant difference between the treatments in unsaturated hydraulic conductivity (Kus) in the soil surface. Saturated hydraulic conductivity (Ks) in the subsoil was very small, although the RB had significantly greater Ks than the CC. / A solute transport experiment investigated the movement of a solute in large soil cores of the RB and CC treatments. Derived parameters from a transfer function model were used to assess the solute transport characteristics. This showed that under nearly saturated conditions the CC had significantly greater solute spreading than the RB. Furthermore, the transport volume (θst) to θv ratio was smaller in the RB which indicated a greater proportion of preferential flow. These and other data suggested that the RB had a better connected and more stable pore network. / Soil macropore structure was quantified using image analysis of resin-impregnated soil. Samples were taken twice; the first samples showed that the RB had improved pore connectivity, slightly greater porosity and a pore network with smaller sized pore components than the CC. In comparison, at the second sampling time the structural parameters of the two treatments were similar. / Uncertainty exists in the scenario of higher rainfall or of the longer-term changes of soil properties under RB cropping. Nevertheless after three years of measurements, this thesis concludes that most soil physical properties of RB are distinctly better for cropping than under CC systems.

The digital lodgement of cadastral survey data in Victoria

Falzon, Katie Unknown Date (has links) (PDF)
An integral part of the Victorian land registration system is the lodgement of cadastral data.Originally data was lodged to support the operation of the land market and the legal rights ofthe individual owner. The purpose for which it was designed, coupled with the technologythat was available at the time, resulted in a paper based system of plans and indexes. Due tomany external factors, the current land registration system has essentially remained the samefor the past 130 years. However the need for cadastral information means that plan lodgementnow serves a wider range of needs, and although changes have been made to the system, itwould seem that document-based systems are reaching the limit of cost-effectiveimprovement.A detailed study of the Victorian system of data lodgement has shown there to be severalinefficiencies within the system, many of which would benefit by the shift to a digitalenvironment. Research has also shown that the Victorian surveying profession is actuallyquite prepared to adapt to a digital environment, with many surveyors already preparing orsubmitting plans digitally.Other jurisdictions that are experiencing similar problems to Victoria have progressedsubstantially in this area and form ideal examples to learn from. The study of thesejurisdictions has shown that although technically the process of lodging data in a digitalformat is quite straightforward, there are still many technical and legal problems that must beresolved.It is envisaged that in the future, data be lodged in a digital format, which would involve there-engineering of the Victorian land registration system as we know it. This thesis exploresthe concept of the lodgement of cadastral survey data in a digital format, the issues associatedwith such a change and the long term benefits it will provide to the surveying, mapping andland development industries.
