Water managers for the City of Phoenix face the need to make informed policy decisions regarding long-term impacts of climate change on the Salt-Verde River basin. To provide a scientifically informed basis for this, we estimate the evolution of important components of the basin-scale water balance through the end of the 21st century. Bias-corrected and spatially downscaled climate projections from the Phase-3 Coupled Model Intercomparison Project of the World Climate Research Programme were used to drive a spatially distributed variable infiltration capacity model of the hydrologic processes in the Salt-Verde basin. From the many Global Climate Model's participating in the IPCC fourth assessment, we selected a five-model ensemble, including three that best reproduce the historical climatology for our study region, plus two others to represent wetter and drier than model average conditions; the latter two were requested by City of Phoenix water managers to more fully represent the full range of GCM prediction uncertainty. For each GCM, data for three emission scenarios (A1B, A2, B1) was used to drive the hydrologic model into the future. The model projections indicate a statistically significant 25% decrease in streamflow by the end of the 21st century. Contrary to previous assessments, this is not caused primarily by changes in the P/E ratio, but is found to result mainly from decreased winter precipitation accompanied by significant (temperature driven) reductions in storage of snow. The results show clearly the manner in which water management in central Arizona is likely to be impacted by changes in regional climate.

The purpose of this research study was to conduct an ethnographic assessment for an Environmental Impact Statement (EIS) of a proposed expansion plan for the Santa Fe Ski Area located in the Sangre de Cristo Mountains north of Santa Fe, New Mexico. Along with expansion into forest areas outside the existing Special Use permit boundaries, the proposed plan includes new buildings, parking lots, lifts, ski runs, and snowmaking within the existing ski area boundary. The ethnographic assessment concentrates on those cultural resources known to be in the area, as identified by Pueblo participants in the research study. This project had three objectives: a) what impact would the project have on the traditional uses, cultural uses, values, and belief practices of Tesuque Pueblo and other Pueblos' uses of the area; b) how would the ski area expansion affect the traditional use area of the Tesuque Pueblo and other Pueblos; and c) what specific areas of traditional cultural use, including those of Hispanic origin, would be affected by the proposed alternatives.

The majority of offshore wind farms utilize monopile substructures. As these wind farms are typically located in water depths less than 30 meters, the effect of breaking waves on these structures is of great concern to design engineers. This research investigation examines many of the practical considerations and alternative ways of estimating breaking wave forces. A survey of existing European wind farms is used to establish a realistic range of basic design parameters. Based upon this information a parametric study was pursued and a series of realistic design scenarios were evaluated. Comparisons include the sensitivity to the wave force model as well as to analytical and numerical wave theories used to evaluate the wave kinematics. In addition, the effect of different kinematics stretching techniques for linear waves is addressed. Establishing whether the bathymetry will induce spilling or plunging wave breaking is critical. Spilling wave breaking can be addressed using existing wave and wave force theories; however for plunging wave breaking an additional impact force must be introduced. Dimensionless design curves are used to display pertinent trends across the full range of design cases considered. This research study provides insight into the evaluation of the maximum breaking wave forces and overturning moment for both spilling and plunging breaking waves as a function of bottom slope.

Flying insects face challenging conditions such as rainfall, fog, and dew. In this theoretical and experimental thesis, we investigate the survival mechanisms of the mosquito, Anopheles, through particles of various size. Large particles such as falling raindrops can weigh up to fifty times a mosquito. Mosquitoes survive such impacts by virtue of their low mass and strong exoskeleton. Smaller particle sizes, as present in fog and insecticide, pose the greatest danger. Mosquitoes cannot fly through seemingly innocuous household humidifier fog or other gases with twice the density of air. Upon landing, fog accumulates on the mosquito body and wings, which in small quantities can be shaken off in the manner of a wet dog. Large amounts of dew on the wings create a coalescence cascade ultimately folding the wings into taco shapes, which are difficult to dry. The insights gained in this study will inform the nascent field of flapping micro-aerial vehicles.

The extraction of raw materials has environmental impacts. Forestry and the extraction of coal, oil, natural gas, gold and other minerals can have serious impacts on the environment. Exploration and evaluation, development activities, production and mine closure result in high costs. The years of waiting between the start of exploration, commencement of production and mine closure create specific challenges in accounting for mining organisations. Most of the damages caused by mining activities cannot be hidden because of the processes involved, it is best to prevent it rather than avoidance. It is important to implement Environmental Management Accounting (EMA), which will assist in presenting a decision-making system for corporations. The system measures and promotes environmental performance by identifying effective cost assessment structures. This study assessed the awareness of environmental management accounting in the mining industry. An analytical methodology was used. A questionnaire was administered to a selected group of participants. It was based on the employee’s understanding of their organisation’s practices or point of view on environmental issues to build a case about the awareness of environmental management accounting. Selected participants were mine management or mine production personnel, financial practitioners and environmental practitioners from different mining organisations in the Gauteng, Mpumalanga and North-West provinces of the Republic of South Africa. All participants in the study are employees in the mining industry. Mine management is less aware of environmental management accounting compared to environmental and financial practitioners. Mine production personnel only perceive environmental issues as costs to the operations. This group rated compliance with regulation as the main driver for their organisation’s environmental management system. Gauteng province is more aware of environmental management accounting compared to Mpumalanga and North West provinces. Organisations with high annual turnover tend to disclose more financial environmental information than those with low annual turnover. Organisations explain and classify environment-related costs differently according to the intended use of the cost information. There are standards and measures to collect and record environmental and accounting information stipulated in ISO14001 including environmental management systems (EMS) in different organisations. Systems and measures put in place ensure good environmental performance in the mining operations. The tracking and reduction in the amount of energy, water and materials used by organisations may result in environmental benefits. Employees should have environmental cost information associated with their operations in order to minimise environmental impacts of an organisation. The findings of the study indicated low levels of awareness of environmental management accounting in the mining industry; however, there is a higher level of awareness of environmental impacts and costs, environmental management system and financial environmental information. The level of rating at which organisations generate and record physical and monetary information of environmental management accounting is higher. / MBAm, North-West University, Potchefstroom Campus, 2014

Reinforced Concrete (RC) bridge piers, RC columns along exterior of buildings or those located in parking garages are designed to support large compressive axial loads but are vulnerable to transverse out-of-plane loadings, such as those arising from impacts or explosions. To address a lack of understanding regarding blast and impact response of RC members and the need for retrofit techniques to address deficiencies in existing structures, a multi-disciplinary team including various institutes of the National Research Council and the University of Ottawa has initiated work towards developing a fibre reinforced polymer composite protection system for RC columns subjected to extreme shocks. This thesis will focus on the impact program of the aforementioned project. An extensive literature review was conducted to gain a better understanding of: impact loading and associated dynamic effects; experimental testing of RC members subjected to impact; experimental testing of axially loaded members; and retrofit methods for the protection of RC under impact loading. Five half-scale RC columns were constructed and tested using a drop-weight impact machine and two additional specimens were tested under static loading. Deflections, strain distributions within the columns, impact loads and reaction loads were measured during the testing of the built RC members. Comparisons of experimental datum were established between members with differing levels of axial load and between a retrofitted and a non-retrofitted member. Single-degree-of-freedom analysis was used to obtain the predicted response of certain columns under impact loading allowing for comparisons with experimental data.

It is generally accepted that the environment has three inter-dependent components: economic, socio-political and natural Consequently, integrated environmental management coupled with sustainable development is critical, and in order to achieve this goal, effective guidelines and implementable legislation are necessary. This evaluation aims to determine and compare the effectiveness of the South African and Malawian environmental impact assessment (EIA) legislation, using the comparative criteria set out by Wood (1995, 2003), and accordingly to determine whether any further amendments are necessary to improve the effectiveness of these countries' EIA systems. In the Southern African Development Community (SADC) region, it is particularly important that environmental legislation and policies are aligned across borders, to allow for better integration of these economies. The alignment of EIA systems in the SADC region could enhance regional sustainable development if managed using similar criteria. The primary objective of this study is to compare the EIA legislation of South Africa and Malawi using Wood's (1995, 1999, 2003) 14-point evaluation criteria. The effectiveness and not the implementation and practice of the legislation is being compared. The secondary objective of this study is to determine whether Wood and Roux's recommendations have been incorporated into the South African National Environmental Management Amendment Act 8 of 2004 and the January 2005 draft EIA regulations, and whether South African legislation meets Wood's 14 criteria for a sound EIA system. In the South African evaluation, 11 of Wood's 14 criteria are met, while an additional two criteria are partially met and one criterion is failed, resulting in an overall improvement in the South African EIA system. The Malawian EIA legislation meets 11 of Wood's 14 criteria, with three criteria being partially met, in principle making it more effective than the South African EIA legislation. However, although Malawi theoretically has a slightly more effective EIA legislation than South Africa, in practice this is not the case. Ideally, when South Africa's updated EIA legislation is published it will meet with all 14 of Wood's criteria for an effective EIA system based on international standards. / Thesis (M.

This thesis investigates British fictional representations of India in novels, plays and poetry from 1772 to 1823. Rather than simply correlating literary portrayals to shifting colonial context and binary power relationships, the project relates representations to the impact of India on British popular culture, and print capitalism’s role in defining and promulgating national identity and proto-global awareness. The study contends that the internal historical development of the literary modes – the stage play, the novel and verse – as well as consumer expectations, were hugely influential in shaping fictional portrayals of the subcontinent. In addition, it argues that the literary representations of India were contingent upon authors’ gender, class and their lived or lack of lived experience in the subcontinent. The project seeks to use literary texts as case studies to explore the growing commoditisation of culture, the developing literary marketplace and an emerging sense of national identity. The thesis proposes that the aforementioned discourses and anxieties are embodied within the very literary forms of British India narratives. In addition, it seeks to determine shifts in how Britain’s relationship with the subcontinent was imagined and how events in colonial India were perceived by the general public. Furthermore, the project utilises literary texts as sites to explore the discursive and epistemological strategies that Britons engaged in to either justify or confront their country’s role as a colonising nation.
