Drainage area is a measure of the number of acres feeding into a creek. Drainage area threshold is the amount of acreage required for the creek to be included on a map. Watersheds mapped according to higher drainage area thresholds will show creek systems that are shorter and concentrated at the bottom of the watershed. Watersheds mapped according to lower drainage area thresholds show creek systems that are longer and extend further up the watershed. Since all watersheds are subject to different land uses, soil types, geology, etc., they should be mapped according to different drainage area thresholds. Headwaters are where creeks begin. There is empirical evidence that properly functioning headwaters significantly reduce erosion, improve water quality, slow stormwater flows, and provide habitat. If municipalities use lower drainage area thresholds to define their creeks, they can include more headwaters in their creek setback requirements. This professional report identifies the Harris Branch watershed as being under relatively more pressure to develop and exhibiting more environmental risk than other watersheds in Austin, Texas’ Desired Development Zone. Creeks in the watershed are redrawn according to reduced drainage area thresholds using a simple ArcGIS analysis. The analysis reveals a critical mass where creek setbacks appear to be too extensive. If creeks with a drainage area of 5 acres are protected by development code, the setbacks created have excessive branching that could be too restrictive for development. A critical mass ratio should be considered when determining which drainage area threshold is most appropriate for a watershed. The critical mass ratio is equal to the number of branches allowed per a specified distance of creek centerline. The process of identifying this critical mass ratio can help growing cities find a balance between the need to encourage development in designated areas and the need to protect natural creek systems everywhere. I recommend that municipalities review the effects of reducing drainage area threshold for each watershed, and then identify the drainage area threshold that, when protected by setback requirements, allows for extended and connected greenways as well as an increase in density. / text

It has over the last 20 years occurred a series of extreme weather events around the worldthat caused damage to people and buildings. Many published reports have studied thedeveloping countries and less studies has been conducted on the construction industry andthe economically powerful countries.Sweden has been spared from the most extreme events but still suffered some events whichcan be considered extreme for the country. Therefore, the aim of this report is to study howthe construction industry in Sweden works with risk management, as a preventive measureagainst extreme weather events. The intention has been to find out how aware the industryis of climate change.Studies of this kind have not been carried out previously in Sweden and therefore this studyuses a qualitative approach to conduct the study. Thorough studies on risks, riskmanagement and all its processes have been performed. The focus has been on the generalrisks and the risks associated with extreme weather conditions. This is to analyze how theconstruction industry works with risks of this kind. Interviews have been conducted withproject managers and production managers at a major Swedish construction company to becompared with the written theory.The study and 10 interviews have been conducted at Skanska Hus in Stockholm to get apicture of how different projects in the same region are working with risk managementlinked to extreme weather events as they have the same weather conditions.The study concluded that the studied company was very good at working with riskmanagement but they were less prepared for extreme weather than had been expected. Thisgave the impression that the industry as a whole are in need to be informed about what kindof impacts climate change has on production and the working environment for the future.The investigation showed that it still needs improvements and more knowledge in this areasince climate change is a fact.

The solar wind has an important impact on the Earth and its magnetic field. Among the solar wind perturbations, there can be jumps in the solar wind dynamic pressure as well as strong magnetic excursions in the z-component of the Interplanetary Magnetic Field (IMF B_(Z )). When coronal mass ejections and other solar disturbances take place in the solar wind, there can be clear changes in the global geomagnetic field, as measured by a magnetic index called Sym-H. In this thesis some unusual events were found for which there were large fluctuations either in the solar wind dynamic pressure or in the IMF B_Z but not simultaneously in both. These events suggest that the response of the geomagnetic field to the dynamic pressure fluctuations of the solar wind is variable. In particular, it was found that the earthward component (x-component) of the IMF appeared to influence the magnitude of the Sym-H response. By contrast, there was no visible impact of the y-component of the IMF. In a second exceptional event it was found that the IMF was changing substantially while the solar wind dynamic pressure remained very constant. From this study a time delay between the IMF B_Z component and the resulting Sym-H was found to be of the order of 60 to 90 minutes.

After a period during which Storm Jameson’s restricted literary identity has been that of the politically engaged woman writer, critical interest in the intellectual and stylistic complexities of her work is now reviving. Yet Jameson’s background in early English modernism and the manner in which it enriches her writing continues to pass unnoticed. This thesis uncovers new evidence of Jameson’s immersion in the early English modernisms of Alfred Orage’s Leeds Arts Club and New Age journal and of Dora Marsden’s journals, the New Freewoman and the Egoist, as an avant-garde student before the Great War. Drawing analogies with the post-colonial notions of ‘Manichean delirium’ and of ‘writing back to the centre’, this thesis argues that, subsequently – as a provincial socialist woman writer struggling to make her way at the predominantly male and elitist cultural centre – Jameson developed a vexed outsider-insider relation to English modernism which she expressed during the 1920s in a series of intertextual novels critiquing the contemporary cultural scene. It examines each of these novels chronologically, beginning with Jameson’s critique of the early modernisms of Orage, Marsden and associated writers in her first two novels, before moving on to her engagement, in turn, with the work of D. H. Lawrence, Virginia Woolf and Wyndham Lewis. Employing a socially oriented model of intertextuality, this thesis reads each novel synchronically as a sceptical and often witty probing of some of the polarised, and frequently contradictory, positions taken within the modernist debate. It also interprets the 1920s fiction diachronically as a developmental journey towards what Jennifer Birkett terms the ‘stylised realism’ of the 1930s and 40s, in which William James’s Pragmatism plays a central role, allowing Jameson to assimilate those intellectual and stylistic elements within English modernism that she values before leaving the rest behind.

This thesis proposes an architecturally integrated stormwater system and research facility in the town of Wasagaming, Riding Mountain National Park (RMNP), Manitoba. The design proposal provides four-season, interior and exterior space for the integration of resource management operations and park visitor experiences. Visible integration of infrastructure, building and landscape cultivate destination-based travel to RMNP while reducing human impacts on the ecosystem. Aging infrastructure and diminishing federal funding make responsible ecological and cultural management of parks increasingly difficult. Integration of research and tourism as a component of visitor experience at parks is one way of addressing cost-effective co-location of programme, ensuring future funding can be generated for resource management.

Historic and future extreme precipitation and wind events over southern Baffin Island, more specifically Iqaluit, Kimmirut, Pangnirtung and Cape Dorset are examined. Two sets of modeled re-analysis data, the Canadian Regional Climate Model (CRCM) forced with European Centre for Medium-Range Weather Forecasts Regional Analysis 40 (ERA40) and the other the North American Regional Re-analysis (NARR) dataset were used to characterize the atmosphere during historic events. Two sets of CRCM data forced with Canadian Global Climate Model (CGCM) data, one from 1961-1990 and the other from 2041-2070, are compared to assess the changes in extreme events in the future. Extreme events were defined by daily precipitation and sustained wind thresholds. Based on the CRCM future projection, events were inferred to increase in intensity for all communities and increase in frequency for 3 of the 4 communities. A shift in the Arctic storm season was also inferred in the future projection.

This study aims to investigate the stable isotopic characteristics of meteoric and ground waters, and to obtain spring flow rates in the Coronet Peak Skifield, Queenstown. Spring flows were gathered during the winters of 2008 and 2009, whilst water samples were collected from precipitation, springs, reservoirs and groundwater during July, August and September 2009. The spring flows were examined and the water samples were analysed for δD and δ¹⁸O values using the CF-IRMS at the University of Canterbury. A database has been gathered from all natural water sources to give a local meteoric water line (LMWL) for the area that fits clearly with the global meteoric water line. The LMWL has an R2 value of 0.97 and the equation is δD = 8 δ¹⁸O +10. An understanding of evaporation as it occurs in the water storage reservoirs of the mountain has also been obtained, giving rise to a local evaporation line. The stable isotope ratios of hydrogen and oxygen within precipitation have been used extensively to characterise the hydrogeology with emphasis on altitude effects, storm duration and variations in storm track trajectories. Of these three phenomena, it is the trajectory of the storm track that is best shown to affect the composition of precipitation in this area. The air masses advancing on the study area from the north being more depleted in their isotopic signatures, with approximate δD and δ¹⁸O values of –130‰ and -16‰. The air masses approaching from a southerly direction are more positive in comparison, having approximate δD and δ¹⁸O values of –65‰ and -9‰. The altitude effect in precipitation on the Skifield has led to an altitude gradient being found: for every 100-metre increase in elevation, δ¹⁸O decreases by 0.71‰. However there were some inconsistencies. The influence on precipitation from storm duration is also inconsistent in this area. The R2 values range from 0.14 to 0.99, but this method does not take into account the position of the individual samples. Some samples did not plot in the expected order that is governed by a decrease in stable isotopic ratios with storm duration. The stable isotopic compositions within meteoric waters can be used as tracers of water sources. The isotope date of the springs also infers an altitude effect. The springs gave an altitude gradient of a decrease –0.43‰ with each 100-metre increase in elevation. This indicates that precipitation is the main influence on the stable isotopic composition of the springs in this area. However, data shows differences between the current precipitation and the groundwater compositions, indicating that present precipitation is not flowing from the springs, past precipitation is. The stable isotopic compositions of the springs have also been correlated with groundwater isotope data and suggest the sources of the springs are groundwater dominated. Although some springs compositions indicate an influence by current precipitation. This is shown by a negative stable isotopic trend in the precipitation sampled in August, corresponding with a relatively negative stable isotopic composition in some springs during this time period. Monitoring of spring flows on Coronet Peak have led to an average winter flow rate being established of 26.5 litres per second. Spring flow rates range from 0.25 – 6 litres per second. This monitoring has indicated the springs of the greatest yield that are not already being utilised on the Skifield. It is these springs that should be further investigated as to whether they would provide a sustainable source of water on the mountain. This locally derived water would then be utilised for the purposes of artificial snowmaking and other activities and amenities that are currently operated by NZ Ski on Coronet Peak.
