Master of Science / Department of Geology / Allen W. Archer / Abstract This study compares the tidally influenced facies found within the Tonganoxie Sandstone Member (Stranger Formation, Douglas Group) (Upper Pennsylvanian) of northeastern Kansas with similar facies directly observed in the upper intertidal mudflats of Turnagain Arm of Cook Inlet (Alaska, USA). The two settings contain strikingly similar facies that are characteristic of upper macrotidal estuaries with a strong influence of tidal activities. Identical aspects and features found within both settings include rhythmic vertical variation in stratum thicknesses (cyclic tidal rhythmites), high estimated sedimentation and aggradation rates, and biogenic and physical sedimentary structures (e.g., drag marks, raindrop impressions, arthropod traces and tetrapod trackways, zigzag burrows, runoff washouts, and upright trees, among others). Tidal rhythmites are the most important evidence that is indicative of the tidal influence on the depositional processes of these two study areas. Such cyclic tidal rhythmites have been reported and described from several Carboniferous settings in the eastern USA. Modern analogs to these Carboniferous rhythmites are usually found within upper macrotidal estuarine depositional environments, especially within fluvio-estuarine transitional zones. These environments are distributed over a wide range of modern latitudes. Using cyclic tidal rhythmites as modern analogs for interpreting similar ancient facies is a powerful tool for paleogeographic and paleoenvironmental reconstructions, although it is somewhat a new approach.

A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements of the degree of Master of Science in Geology Johannesburg, 1998 / This study determines the potential of prerncting pollution to ground water by sanitary landfills. The tracing capabilities of both stable and radioactive environmental isotopes are also evaluated. Four landfills were selected, the Linbro Park and Waterval sites in Johannesburg, and the Bloemfontein northern and southern landfill sites. The sites all differ in geological environment, size. age and physiographic setting. [Abbreviated Abstract. Open document to view full version] / MT2017

Caraguatatuba desde 2007 destina o seu lixo a um aterro privado, em Santa Isabel - SP, localizado a 140 km de distância. Nesse sentido, existem algumas propostas para a problemática do lixo na região. Dentre elas está a implantação de um aterro sanitário regional. Além desse impasse, a partir da década de 1950, Caraguatatuba vem sofrendo um processo crescente de ocupação do solo e uso turístico desordenado, sendo que atualmente a região se encontra em grande processo de transformações socioambientais, o que poderá ocasionar uma grande expansão urbana. Com o propósito de contribuir para os estudos que vêm sendo realizados no Litoral Norte Paulista, em especial o projeto Urban Growth, vulnerability and adaptation: social and ecological dimensions of climate change on the coast of São Paulo (processo n.2008/58159-7), esse trabalho tem como objetivo fazer uma análise energética e ambiental sobre o atual modelo utilizado em Caraguatatuba, em relação à coleta e disposição final dos RSU e a proposta da implantação de um aterro sanitário para a região. Essa análise teve como base o levantamento realizado no município de Caraguatatuba, durante o período de setembro de 2009 a novembro de 2010. Verificou-se que no ano de 2010, foram coletados em média 3.531 t/mês de RSU, com um gasto anual de R$ 8.430.834. Durante o transporte do lixo para o aterro sanitário em Santa Isabel - SP, são emitidas em média 24.360 t/CO2 na baixa temporada e 49.560 t/CO2 na alta temporada. Verificou-se também, diante dos cálculos realizados no trabalho, que se for considerada a utilização da tecnologia de aproveitamento do biogás, seria possível gerar energia equivalente a 60.480 MJ/dia, suficiente para abastecer 2.546 residências no município / Abstract: The issue of municipal solid waste (MSW) in Caraguatatuba, as well as other cities in the North Coast of São Paulo, has been widely discussed, since the region lacks a licensed landfill and designed all the garbage in private landfills located in the Vale do Paraiba. Caraguatatuba designed the city's garbage in a private landfill located in Santa Isabel - SP, situated 140 km away, beginning in the year 2007. There are some proposals being discussed for the solid waste problem in the region. Among them is a regional landfill for the North Coast of São Paulo. Beyond this impasse, Caraguatatuba is experiencing a process of increasing land use and disordered tourism starting on the decade of 1950, and nowadays, the region is in a great socioenvironmental change process, which may lead to a major urban expansion. Aiming to contribute with studies that have been done on the São Paulo's North Coast, in special the project: Urban Growth, vulnerability and adaptation: social and ecological dimensions of climate change on the coast of São Paulo (process n.2008/58159-7), this study aims to analyze environmental and energy on the current model used in Caraguatatuba, regarding the collection and disposal of municipal solid waste and the proposed deployment of a landfill for the region. This analysis was based on a survey conducted in the city of Caraguatatuba, during the period from September 2009 to November 2010. It was found that in 2010, was collected an average of 3,531 t/month of MSW, with an annual expenditure of R$ 8,430,834. When the garbage is transported to the landfill in Santa Isabel -SP, it emits an average of 24,360 t/CO2 in the low season and 49,560 t/CO2 in high season. It was verified through the calculations, that using the landfill gas technology, it would be possible to generate 60,480 MJ/day, enough energy equivalent to power 2,546 homes in the city / Mestrado / Planejamento de Sistemas Energeticos / Mestre em Planejamento de Sistemas Energéticos

Municipalities are increasingly facing solid waste disposal problems due to lack of sanitary landfill sites, high costs of landfill management and increasingly stringent environmental standards. Consequently, they are turning toward innovative disposal practices to alleviate these problems. However, very little comprehensive information is available to decision makers on the range of options available in resource recovery development and the factors that can influence choices. This thesis tests the hypothesis that there are a definable set of factors or circumstances that have led resource recovery developers to make specific decisions regarding ownership, operation, financing, system technology, and air pollution control technology. The thesis is divided into three stages: development of case studies on 9 resource recovery facilities in the state of Virginia; development and analysis of a nationwide survey to test the patterns illustrated in these case studies; and finally, the development of a guide for resource recovery developers that will serve as preliminary guidance in their choice of development options. / M.
