Bogart, Tianna A. "Sensitivity of a global climate model to the urban land unit." Thesis, University of Delaware, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=3598618.
With more than half of the world's population living in urban areas, it is important that the relationships between the urban environment and climate are better understood. The current research aims to continue the effort in assessing and understanding the urban environment through the use of a global climate model (GCM). Given the relative newness of the presence of an urban land type and model in a GCM, there are many more facets of the urban-climate relationship to be investigated. By comparing thirty-year ensembles of CAM4 coupled with CLM4 both with (U) and without (Un) the inclusion of the urban land type, the sensitivity of the atmospheric model to urban land cover is assessed. As expected, largest differences tend to be in the Northern Hemisphere due to the location of most of the globe's densest and expansive cities. Significant differences in the basic climate variables of temperature and precipitation are present at annual, seasonal, and monthly scales in some regions. Seasonality to the urban influence also exists with the transition months of Spring and Fall having the largest difference in temperatures. Of the eleven regions defined by Oleson (2012), three were most impacted by the presence of urban land cover in the model—Europe, Central Asia, and East Asia.
Since urban attributes can vary greatly within one world continent, the sensitivity of regional climates to the urban type parameters is also explored. By setting all urban land cover to only one urban density type, the importance of city composition on climate, even within the same city, is highlighted. While preserving the distinct urban regional characteristics and the geographical distribution of urbanized areas, the model is run with homogeneous urban types: high density and tall building district. As with the default urban and excluded urban runs, a strong seasonality to the differences between the solo-high-density simulation and default urban (UHD – U) and solo-tall-building-district-density simulation and default urban (UTBD – U) exists. Overall, the transition and winter months are most sensitive to changes in urban density type.

A preocupação com os chamados impactos ambientais urbanos fomentou um maior interesse nas pesquisas, principalmente aquelas voltadas para as análises climáticas, na escala urbana. A cidade por consequência de seu processo de organização e estruturação desenvolveu um clima totalmente particular, o clima urbano, isso é possível através da retirada da vegetação original e a inserção dos chamados equipamentos urbanos, como por exemplo, as vias impermeabilizadas, as construções, a verticalização, além da circulação de pessoas e veículos que irão contribuir para maior aquecimento da atmosfera local. Os materiais presentes no meio urbano vão apresentar diferentes valores de albedo, emissividade, absortividade e irradiação e consequentemente, estes condicionarão diferentes valores de temperatura de superfície e que influenciarão na temperatura do ar. O presente estudo tem por objetivo analisar o comportamento do clima urbano na cidade de Juiz de Fora- MG, onde foram trabalhadas 35 regiões urbanas, localizadas ao longo do curso do Rio Paraibuna. O estudo busca através da aplicação de um modelo geoespacial, interligar variáveis que possuem uma conexão direta com a temperatura de superfície e indireta com a temperatura do ar. Este conjunto de dados permitiu alcançar uma maior compreensão, viabilizou a espacialização e consequentemente uma visualização de como se distribuem as áreas e suas diferentes capacidades de criarem distintos campos térmicos na cidade.Além disso, para fins de validação do modelo, foi feita uma correlação estatística entre o modelo matemático proposto e a temperatura de superfície obtida na faixa do infravermelho termal. O modelo utilizado provou possuir consistência para ser adaptado a fim de ser replicado em diferentes cidades com especificidades térmicas além de ser viável a integração de outras informações e dados.
Concern about so-called urban environmental impacts has fostered greater interest in research, especially those focused on climate analysis, on the urban scale. The city as a result of its process of organization and structuring has developed a totally particular climate, the urban climate, this is possible through the removal of the original vegetation and the insertion of so-called urban equipment, such as waterproofed roads, constructions, verticalization, besides the circulation of people and vehicles that will contribute to greater warming of the local atmosphere. The materials present in the urban environment will present different values of albedo, emissivity, absorptivity and irradiation and consequently, these will condition different values of surface temperature and that will influence the air temperature. The present study aims to analyze the behavior of the urban climate in the city of Juiz de Fora- MG, where 35 urban areas were located along the course of the Paraibuna River. The study searches through the application of a geospatial model, interconnecting variables that have a direct coexistence with the surface temperature and indirect with the air temperature. This dataset allowed to reach a greater understanding, made possible the spatialization and consequently a visualization of how the areas are distributed and their different capacities to create different thermal fields in the city. In addition, for purposes of validation of the model, a statistical correlation was made between the proposed mathematical model and the surface temperature obtained in the thermal infrared range. The model used proved to have consistency to be adapted in order to be replicated in different cities with thermal specificities besides being feasible the integration of other information and data.

The Urban Heat Island (UHI) was investigated using satellite data, ground observations, and simulations with an Urban Canopy Parameterization in a numerical weather prediction model. Satellite-observed surface skin temperatures at Xi'an City and Oklahoma City (OKC) were analyzed to compare the UHI intensity for the two inland cities. A larger population density and larger building density in Xi'an City creates a stronger skin-level UHI effect. However, ground observed 2-m surface air temperature (Tair) data showed an urban cooling island (UCI) effect that occurred over an urban region in OKC during the daytime of July 19, 2003.
The sensitivity and accuracy of an Urban Canopy Model were evaluated by comparing simulation results between the urban and rural areas of OKC. The model reproduced skin temperature differences between the rural and urban area and reproduced a UCI effect in OKC. Furthermore, the Weather Research and Forecasting (WRF)/Noah/Single-Layer Urban Canopy Model (SLUCM) simulations were also compared with ground observations, including wind speeds, wind directions, and energy fluxes. Although the WRF/SLCUM model failed to simulate these variables accurately, it reproduced the diurnal variations of surface temperatures, wind speeds, wind directions and energy fluxes reasonably well.

Buildings represent 40 percent of the end-use energy. Thus, they constitute a key point of the energy saving policies. Recently, climate modeling systems that include a mesoscale atmospheric model, sophisticated urban parameterizations have been developed to account for the complexity of the urban climate and its interactions with the building energy loads. This study aims to assess the capability of such climate modeling systems to provide climate and energy guidelines to urban planners. For this, we used the research collaborative WRF/ARW-BEP+BEM climate modeling system and performed sensitivity tests considering the territory of the Eurodistrict in 2010, and then in 2030. The results reveal that the climate modeling system achieves estimating the building energy needs over the study area, but also indicate that the building energy needs are more sensitive to the building intrinsic properties and occupant behavior than to the urban forms and their induced urban heat island

Die Auswirkungen des Klimawandels auf die Gestaltung der städtischen Wasserinfrastruktur wie Regenwasser, Kanalisation und Trinkwassersysteme werden immer wichtiger. Eine wachsende Anzahl von Belegen zeigt, dass der Wassersektor nicht nur durch den Klimawandel beeinflusst werden wird, aber er wird zu reflektieren und liefern viele seiner Auswirkungen durch Überschwemmungen, Dürren oder extreme Niederschlagsereignisse. Die Wasserressourcen werden sich in Quantität und Qualität verändern, und die Infrastruktur von Regen-und Abwasseranlagen kann einer größeren Gefahr von Schäden durch Stürme, Überschwemmungen und Dürren ausgesetzt sein. Die Auswirkungen des Klimawandels werden zu mehr Schwierigkeiten im Betrieb gestörter Dienstleistungen und zu erhöhten Kosten für Wasser-und Abwasserdienstleistungen führen. Regierungen, Stadtplaner, und Wasser-Manager sollten daher die Entwicklungsprozesse für kommunale Wasser-und Abwasserdienstleistungen erneut überprüfen und Strategien anpassen, um den Klimawandel in Infrastruktur-Design, Investitionsprojekte, Planung von Leistungserbringung, sowie Betrieb und Wartung einzuarbeiten. Nach Angaben des Intergovernmental Panel on Climate Change hat die globale Mitteltemperatur in den letzten 100 Jahren um 0,7 °C zugenommen, und in der Folge hat sich der hydrologische Zyklus intensiviert mit, zum Beispiel, stärkeren Niederschlagsereignisse. Da die städtischen Entwässerungssysteme über einen langen Zeitraum entwickelt wurden und Design-Kriterien auf klimatischen Eigenschaften beruhen, werden diese Veränderungen die Systeme und die Stadt entsprechend beeinflussen. Das übergeordnete Ziel dieser Arbeit ist es, das Wissen über die Auswirkungen des Klimawandels auf das Regenwasser-System in der Stadt Hilla / Irak zu bereichern. Im Detail ist das Ziel, zu untersuchen, wie der Klimawandel die Siedlungsentwässerung und insbesondere die Regenwasser-Infrastruktur betreffen könnte. Desweiteren soll ein Anpassungsplan für diese Änderungen auf der Grundlage von beispielhaften Anpassungsplänen aus internationalen Fallstudienvorgeschlagen werden. Drei stochastische Wettergeneratoren wurden untersucht, um das Klima und den Klimawandel in Hilla zu verstehen. Stochastische Wettergeneratoren wurden in verschiedenen Untersuchungen und Studien zum Beispiel in der Hydrologie sowie im Hochwasser-Management, Siedlungswasser-Design- und Analyse, und Umweltschutz eingesetzt. Damit solche Studien effizient sind, ist es wichtig, lange Datensätze (in der Regel Tageswerte) haben, so dass der Wettergenerator synthetische tägliche Wetterdaten erzeugen kann, dieauf einem soliden statistischen Hintergrund basieren. Einige Wettergeneratoren können Klimaszenarien für verschiedene Arten von globalen Klimamodellen erzeugen. Sie können unter Verwendung von Interpolationsverfahren auch synthetische Daten für einen Standort generieren, für den nicht genügend Daten vorliegen. Um sicherzustellen, dass der Wettergenerator dem Klima der Region optimal entspricht, sollte gegen die beobachteten Daten geprüft werden, ob die synthetischen Daten ausreichend ähnlich sind. Gleichzeitig unterscheidet sich die Genauigkeit des Wettergenerator von Region zu Region und abhängig von den jeweiligen Klimaeigenschaften. Der Zweck des ersten Teils dieser Studie ist es daher, drei Wettergeneratoren, namentlich GEM6, ClimGen und LARS-WG, an acht Klimastationen in der Region des Gouvernements Babylon / Irak zu testen. LARS-WG verwendet eine semi-parametrische Verteilung (entwickelte Verteilung), wohingegen GEM6 und ClimGen eine parametrische Verteilung (weniger komplizierte Verteilung) verwenden. Verschiedene statistische Tests wurden ausgewählt, um die beobachteten und synthetischen Wetterdaten für identische Parameter zu vergleichen, zum Beispiel die Niederschlags- und Temperaturverteilung (Nass-und Trockenzeit). Das Ergebnis zeigt, dass LARS-WG die beobachteten Daten für die Region Babylon akkurater abzeichnet, als ClimGen, wobei GEM6 die beobachteten Daten zu verfehlen scheint. Die synthetischen Daten werden für eine erste Simulation des städtischen Run-offs in der Regenzeit sowie der Folgen des Klimawandels für das Design und Re-Design des städtischen Entwässerungssystems in Hilla verwendet. Der stochastische Wettergenerator LARS wird dann verwendet, um Gruppen zukünftiger Wetterdaten unter Verwendung von fünf globalen Klimamodellen (GCM), die das gesamte Spektrum der Unsicherheit am besten abdecken, zu generieren. Diese globalen Klimamodelle werden verwendet, um zukünftige Klimaszenarien der Temperatur und des Niederschlags für die Region Babylon zu konstruieren. Die Ergebnisse zeigen, eine Steigerung der monatlichen Temperaturen und eine Abnahme der Gesamtmenge der Regen, wobei es jedoch extremere Regenereignissen mit höherer Intensivität in kürzerer Zeit geben wird. Veränderungen der Höhe, des Zeitpunkt und der Intensität der Regenereignisse können die Menge des Abflusses von Regenwasser, die kontrolliert werden muss, beeinflussen. Die Klimawandel-Prognosen können bestehende regenwasserbedingte Überschwemmungen verschlimmern. Verschiedene Bezirke in Hilla können stärker von Regenfluten betroffen werden als bisher aufgrund der Prognosen. Alle Ergebnisse, die von den globalen Klimamodellen übernommen wurden, sind in täglicher Auflösung und um das Regenwasser-Management-Modell anzuwenden, ist es wichtig, dass alle Daten in einer Mindestauflösung von einer Stunde vorliegen. Zur Erfüllung dieser Bedingung wurde ein eine Aufschlüsselungs-Modell verwendet. Einige Stunden-Niederschlagsdaten waren erforderlich, um das zeitliche Aufschlüsselungs-Modell zu kalibrieren. Da weder die Klimastationen noch die Regen-Messgeräte im Interessenbereich über stundenauflösende Daten verfügt, wurden die Stundendaten von Flughäfen in Bagdad verwendet. Die Veränderungen in den Hochwasserrückkehrperioden sind in den projizierten Ergebnissen des Klimawandels ersichtlich, und eine Rückkehrperiode wird nur dann über Zeit gültig bleiben, wenn sich die Umweltbedingungen nicht ändern. Dies bedeutet, dass Wiederkehrperioden, die für Planungszwecke verwendet werden, öfter als bisher aktualisiert werden müssen, da die auf Grundlage von Daten der letzten 30 Jahre berechneten Werte innerhalb einer relativ kurzen Zeitspanneunrepräsentativ werden können. Während Wiederkehrperioden bieten nützliche Hinweise für die Planung die Effekte von Überschwemmungen und die damit verbundenen Auswirkungen, müssen aber mit Vorsicht verwendet werden, und Extreme, die öfter eintreten könnten als erwartet, sollten berücksichtigt werden. Im Studienbereich mit getrennten Regenwassersystemen zeigt die Simulation des Regenwasser-Management-Modells, dass sich die Anzahl der Oberflächenhochwasser sowie der Überschwemmungen im Zeitraum 2050e-2080 erhöhen wird. Zukünftige Niederschläge werdensowohl die Hochwasser-Frequenz als auch die Dauer von Überschwemmungen erhöhen. Daher ist die Notwendigkeit offensichtlich, zukünftige Situationen in städtischen Entwässerungssystemen zu berücksichtigen und eine gut geplante Strategie zu haben, um zukünftige Bedingungen zu bewältigen. Die gesamten Auswirkungen auf die Siedlungsentwässerungssyteme aufgrund der Zunahme von intensiven Niederschlagsereignissen müssen angepasst werden. Aus diesem Grund wurden Empfehlungen für die Anpassung an den Klimawandel in der Stadt Hilla vorgeschlagen. Diese wurden durch die Zusammenführung von Informationen aus der Prüfung von fünf Fallstudien, ausgewählt aufgrund der Menge und Qualität der verfügbaren Informationen, erarbeitet,. Die bewerteten Städte sind Seattle (USA), Odense (Dänemark), Teheran (Iran), und Khulna (Bangladesch)

Urban development, characterized by the presence of buildings and impervious surfaces, modify the local climate and in particular, enhance the urban heat island (UHI). This phenomenon raises temperatures in cities at night, which could cause discomfort and over-mortality during heat waves. In the context of climate change and important population dynamics, this thesis is carried out in the Rennes Metropolitan area (in Brittany). Firstly, this thesis focuses on the spatial analysis of UHI variability according to land use and urban forms. To observe UHI in the Rennes Metropolitan area, a network of multiple measurement types were implemented at various scale. 1) a network of 22 permanents weather stations located in urban/rural sites; 2) a network of 20 temperature sensors placed in intra-urban area; and 3) a network of temperature measurements in two neighborhoods of Rennes and a small town, Vezin-le-Coquet. Secondly, spatial models of UHI were designed in this thesis at both the urban agglomeration and intra-urban scale. This multi-scale approach produced UHI map for these nesting-scales. Thirdly, this thesis determined the temporal variability of UHI by looking at the interaction between weather types and UHI. This analysis produced a statistical model of daily UHI magnitude according to meteorological observations. This model combined with data from downscaled climate change scenarios provided future projections of UHI. Lastly, this study deals with tools for town planning to prevent intensive UHI. UHI maps and downscaled climate change scenarios defined the risk assessment in the Rennes Metropolitan area

Improving the energy efficiency of buildings and mitigating the urban heat island is a priority, particularly in historical city centres, which are composed of poorly insulated buildings. One of the levers of action envisaged is wall insulation. However, the retrofit of old walls faces numerous obstacles (technological, architectural, urban). In particular, these walls have a specific hygrothermal behavior, which needs to be taken into account to avoid the appearance of pathologies and to correctly estimate energy losses. It is therefore essential to integrate hygrothermal transfers through the walls to effectively simulate old buildings. However, most urban-scale models neglect moisture transfer through walls.This thesis proposes a new numerical method for solving hygrothermal transfers, which is adapted to the various constraints of urban-scale modeling (spatio-temporal resolutions, numerical method, etc.). Validation is carried out in two steps: a numerical part and an experimental part. Numerical validation is based on an inter-model comparison, using fifteen wall compositions and three climates. Experimental validation uses data recorded in several buildings retrofitted with bio-based materials and instrumented in the medieval city centre of Cahors.Then, coupled heat and mass transfer through walls are integrated into the TEB (Town Energy Balance) urban climate model, using the developed and validated method. The suitability of this new version of TEB to represent the medieval town center of Cahors is assessed by comparison with in-situ measurement. A significant improvement is observed when simulating indoor relative humidity. The impact of moisture transfer is discussed at several scales.Finally, the retrofit of the old walls of buildings in the city center of Cahors is studied using several types of thermal insulation positioned inside or outside. These retrofitting scenarios are simulated with the modified version of TEB, including moisture transfer through the walls. Their relevance is compared with regard to energy issues, indoor and outoor comfort, heritage conservation and wall durability. Recommendations are given according to the type of wall

Urban planning and modifications in open spaces are able to promote the improvement of outdoor thermal conditions and thus qualitatively influence the use of open spaces. In this context, this research aims to analyze the thermal sensation of the population of Curitiba and propose a model for predicting thermal sensation suited to local climatic conditions. The study was carried out at the pedestrian street Rua XV de November and adjacent streets. As a whole, fifteen monitoring campaigns were carried out (14 days in the period between January and August 2009 and one day in June 2010), encompassing fifteen different urban situations. The surveys took place between 10h00 and 15h00 on week days and weather data were monitored and personal data collected, using questionnaires. The method comprised four steps: analysis of the relationship between urban characteristics and thermal sensation; analysis of observed thermal sensation vote; analysis of calculated thermal sensation expressed by the indeces PMV, PET and UTCI and proposal of a thermal sensation predictive model for Curitiba. From the analysis of urban attributes and their relationship with climatic variables and thermal sensation, it was concluded that the canyon orientation and the vertical profile of the facades are important to understand the behavior of the climatic variables and to propose suggestions to improve the thermal comfort in urban environment. The analysis of PMV, PET and UTCI indeces showed the need for calibration to evaluate the thermal sensation of the population of Curitiba. The analysis between the observed thermal sensation and the climatic variables showed that the three categories of thermal sensation are mixed among themselves, with no clear distinction between the group of comfort and cold/heat discomfort, making difficult the definition of climatic zones of thermal comfort for Curitiba. Regarding both statistical methods used to develop the thermal sensation predictive model, the Linear Discriminant Function performed better than the Logistic Regression Model and the total success rate of 53% is adequate for the thermal sensation evaluation of the population analyzed.

Thermal simulation of buildings is a requisite tool in the design of low-energy buildings, yet, definition of weather boundary conditions during simulation of urban buildings suffers from a lack of data that accounts for the UHI effect. To overcome barriers preventing the use of more representative climate data in building thermal simulations, this thesis evaluates two recently developed methods for generating urban weather files from a rural station. The two methods examined are computationally inexpensive. The first method is the urban weather generator (UWG) a model developed by Bueno et al. and the second is a temperature alteration algorithm developed by Crawley 2008. Actual weather data is used to validate the modeled urban data. Actual and modeled weather data is then used in simulation of a typical single-family and small office building to quantify normalized energy use metrics of urban buildings. Applying the UWG to appropriate rural weather data reduces the error associated with energy prediction of an urban single-family building by nearly half (21% to 13%). If the Crawley algorithm is applied to rural data, the resulting weather data will produce simulation results that are lower (- 8%) and upper limits (+ 11%) to the actual urban energy simulation results. For applications that either require feedback with the urban design or have extensive data on the urban morphology we recommend the use of the UWG with a radius of 500 m. For applications that lack urban site data and are order of magnitude estimations, the Crawley algorithm generally is able to provide extremes of the predicted EUI.

The IPCC (Intergovernmental Panel on Climate Change) in its 4th report underlines that the European cities will be impacted by more frequent and more intense scorching episodes due to the climatic modifications taking place during the XXIth century. Peculiar climatic areas, significantly hotter than their surroundings, cities amplify the phenomenon of the urban heat island (UHI). In the example of Paris, the urban islands of heat can exceed by 8°C to 10°C the temperatures measured a few kilometers away. This effect is all the more fatal as heat wave periods become more and more regular (2003, 2006, 2010, 2015). The knowledge on the heat wave phenomenon requires to put in relation spatial and temporal data so as to define high-risk areas.To be able to simulate a heat wave, the SURFEX-TEB model, designed by Météo-France, and CNRS, was chosen. It allows to estimate the temperature in town from weather conditions of the highest atmospheres. These forecasts are particularly important in heat wave periods where temperature differences between cities and suburban areas can exceed 8°C. The heat wave risk, resulting from the UHI, is complex to both understand and represent.To characterize, understand and represent the heat wave by the means of the SURFEX-TEB model, we made a data fusion with measures realized during the 2015 heat wave in Paris. This assimilation highlights, for instance, the accumulation phenomena and the impact of the apartments configuration on the inside and outside temperatures. Our various configurations allowed to confirm the importance of taking into account the internal temperatures during heat waves periods.This research thus proposes a specific and technical perspective of the heat waves representation. Its objectives are a better representation of heat waves and a sharper estimation of their dangerousness according to the phenomenon duration, its intensity and the urban and human features. Maps describing the heat wave and its dangerousness are highlighted thanks to the elaboration of a public Web site.The results of this research rise an interrogation on the thresholds of heat wave. They underline the importance to introduce an internal threshold of heat wave and demonstrate the role of the urban configuration, particularly the types of house. This should contribute to better take into account the dangerousness of heat waves and to improve the mitigation of their effects

The question of urban design of the future is one of the important and critical issues of our society. The global warming, the biodiversity at risk, the economic/social/cultural transitions, the predictions of a significant increase in the urban population, the changes in transportation patterns, and changes in urban forms, to quote only a few... All these questions are at the heart of current issues and are part of the constraints we must face in the urban design of tomorrow. Faced with such a situation, it seems risky today to continue to think of the city with approaches or design processes that are based on yesterday’s realities. As Albert Einstein puts it, "we cannot solve our problems using the same way of thinking that we had when we created them". The environmental issues (global warming, biodiversity, etc ...) are factors of vulnerability in the current city in such a way that it is generally accepted (ScienceNet) that built environments must now , more than in the past, be designed in a way that is "respectful of the environment ". We are encouraged to develop a socially responsible and "environmentally friendly" mentality, an approach that looks beyond the immediate and individual interest to achieving stable, long-term common goals. This is only possible if we use and intelligently and fairly all the resources at our disposal, in this case our knowledge, the natural resources, the socio-economic, the geographical as well as the technological advancements. Because, if technology and digital have become of common daily used by the citizens, urban design and architectural disciplines seems however to have a hard time integrating it completely in an intelligent and systemic way as do today other disciplines such as medicine and aeronautics...This work tries to develop a methodology of urban design based on a combination of digital applications, the effort of a collective intelligence as well as ideas, concepts and techniques proposed by a handful of philosophers, historians, psychologists, architects, town planners above mentioned who marked the history of cities. It is therefore from this heterogeneous marriage of techniques and thoughts augmented by recent geospatial technologies that this research intends to base its point of view on the study of urban complexity in order to try to cope with urban problems in constant form. evolution

Zonas densamente urbanizadas, como as cidades, estão mais vulneráveis a eventos de temperaturas extremas do que as zonas rurais envolventes devido ao efeito de ilha de calor urbano pré-existente. O presente trabalho pretende avaliar a sensibilidade do modelo WRF aos dados do uso do solo e à parametrização da canópia urbana, durante um evento de ilha de calor, na região de Estocolmo. Para o teste de sensibilidade ao uso do solo foram utilizadas três base de dados diferentes. Os resultados mostraram que uma base de dados mais atualizada e com uma maior resolução aumentam a performance do modelo nos campos do vento e da temperatura. Para o teste de sensibilidade às parametrizações da canópia urbana, foram comparadas duas simulações produzidas com o acoplamento de dois modelos de parametrização da canópia urbana (UCM) diferentes, o Single Layer Urban Canopy Model (SLUCM) e o Building Effect Parametrization Model (BEP), utilizando uma base de dados de uso do solo de alta resolução, com três categorias urbanas diferentes. Os resultados mostraram que estes modelos dependem significativamente dos parâmetros utilizados para descrever a geometria e as propriedades da cidade, contudo, o uso do modelo BEP permitiu melhorar a simulação das componentes u e v, enquanto que para o campo da temperatura, os resultados não apresentaram diferenças significativas.

Die Auswirkungen des Klimawandels auf die Gestaltung der städtischen Wasserinfrastruktur wie Regenwasser, Kanalisation und Trinkwassersysteme werden immer wichtiger. Eine wachsende Anzahl von Belegen zeigt, dass der Wassersektor nicht nur durch den Klimawandel beeinflusst werden wird, aber er wird zu reflektieren und liefern viele seiner Auswirkungen durch Überschwemmungen, Dürren oder extreme Niederschlagsereignisse. Die Wasserressourcen werden sich in Quantität und Qualität verändern, und die Infrastruktur von Regen-und Abwasseranlagen kann einer größeren Gefahr von Schäden durch Stürme, Überschwemmungen und Dürren ausgesetzt sein. Die Auswirkungen des Klimawandels werden zu mehr Schwierigkeiten im Betrieb gestörter Dienstleistungen und zu erhöhten Kosten für Wasser-und Abwasserdienstleistungen führen. Regierungen, Stadtplaner, und Wasser-Manager sollten daher die Entwicklungsprozesse für kommunale Wasser-und Abwasserdienstleistungen erneut überprüfen und Strategien anpassen, um den Klimawandel in Infrastruktur-Design, Investitionsprojekte, Planung von Leistungserbringung, sowie Betrieb und Wartung einzuarbeiten. Nach Angaben des Intergovernmental Panel on Climate Change hat die globale Mitteltemperatur in den letzten 100 Jahren um 0,7 °C zugenommen, und in der Folge hat sich der hydrologische Zyklus intensiviert mit, zum Beispiel, stärkeren Niederschlagsereignisse. Da die städtischen Entwässerungssysteme über einen langen Zeitraum entwickelt wurden und Design-Kriterien auf klimatischen Eigenschaften beruhen, werden diese Veränderungen die Systeme und die Stadt entsprechend beeinflussen. Das übergeordnete Ziel dieser Arbeit ist es, das Wissen über die Auswirkungen des Klimawandels auf das Regenwasser-System in der Stadt Hilla / Irak zu bereichern. Im Detail ist das Ziel, zu untersuchen, wie der Klimawandel die Siedlungsentwässerung und insbesondere die Regenwasser-Infrastruktur betreffen könnte. Desweiteren soll ein Anpassungsplan für diese Änderungen auf der Grundlage von beispielhaften Anpassungsplänen aus internationalen Fallstudienvorgeschlagen werden. Drei stochastische Wettergeneratoren wurden untersucht, um das Klima und den Klimawandel in Hilla zu verstehen. Stochastische Wettergeneratoren wurden in verschiedenen Untersuchungen und Studien zum Beispiel in der Hydrologie sowie im Hochwasser-Management, Siedlungswasser-Design- und Analyse, und Umweltschutz eingesetzt. Damit solche Studien effizient sind, ist es wichtig, lange Datensätze (in der Regel Tageswerte) haben, so dass der Wettergenerator synthetische tägliche Wetterdaten erzeugen kann, dieauf einem soliden statistischen Hintergrund basieren. Einige Wettergeneratoren können Klimaszenarien für verschiedene Arten von globalen Klimamodellen erzeugen. Sie können unter Verwendung von Interpolationsverfahren auch synthetische Daten für einen Standort generieren, für den nicht genügend Daten vorliegen. Um sicherzustellen, dass der Wettergenerator dem Klima der Region optimal entspricht, sollte gegen die beobachteten Daten geprüft werden, ob die synthetischen Daten ausreichend ähnlich sind. Gleichzeitig unterscheidet sich die Genauigkeit des Wettergenerator von Region zu Region und abhängig von den jeweiligen Klimaeigenschaften. Der Zweck des ersten Teils dieser Studie ist es daher, drei Wettergeneratoren, namentlich GEM6, ClimGen und LARS-WG, an acht Klimastationen in der Region des Gouvernements Babylon / Irak zu testen. LARS-WG verwendet eine semi-parametrische Verteilung (entwickelte Verteilung), wohingegen GEM6 und ClimGen eine parametrische Verteilung (weniger komplizierte Verteilung) verwenden. Verschiedene statistische Tests wurden ausgewählt, um die beobachteten und synthetischen Wetterdaten für identische Parameter zu vergleichen, zum Beispiel die Niederschlags- und Temperaturverteilung (Nass-und Trockenzeit). Das Ergebnis zeigt, dass LARS-WG die beobachteten Daten für die Region Babylon akkurater abzeichnet, als ClimGen, wobei GEM6 die beobachteten Daten zu verfehlen scheint. Die synthetischen Daten werden für eine erste Simulation des städtischen Run-offs in der Regenzeit sowie der Folgen des Klimawandels für das Design und Re-Design des städtischen Entwässerungssystems in Hilla verwendet. Der stochastische Wettergenerator LARS wird dann verwendet, um Gruppen zukünftiger Wetterdaten unter Verwendung von fünf globalen Klimamodellen (GCM), die das gesamte Spektrum der Unsicherheit am besten abdecken, zu generieren. Diese globalen Klimamodelle werden verwendet, um zukünftige Klimaszenarien der Temperatur und des Niederschlags für die Region Babylon zu konstruieren. Die Ergebnisse zeigen, eine Steigerung der monatlichen Temperaturen und eine Abnahme der Gesamtmenge der Regen, wobei es jedoch extremere Regenereignissen mit höherer Intensivität in kürzerer Zeit geben wird. Veränderungen der Höhe, des Zeitpunkt und der Intensität der Regenereignisse können die Menge des Abflusses von Regenwasser, die kontrolliert werden muss, beeinflussen. Die Klimawandel-Prognosen können bestehende regenwasserbedingte Überschwemmungen verschlimmern. Verschiedene Bezirke in Hilla können stärker von Regenfluten betroffen werden als bisher aufgrund der Prognosen. Alle Ergebnisse, die von den globalen Klimamodellen übernommen wurden, sind in täglicher Auflösung und um das Regenwasser-Management-Modell anzuwenden, ist es wichtig, dass alle Daten in einer Mindestauflösung von einer Stunde vorliegen. Zur Erfüllung dieser Bedingung wurde ein eine Aufschlüsselungs-Modell verwendet. Einige Stunden-Niederschlagsdaten waren erforderlich, um das zeitliche Aufschlüsselungs-Modell zu kalibrieren. Da weder die Klimastationen noch die Regen-Messgeräte im Interessenbereich über stundenauflösende Daten verfügt, wurden die Stundendaten von Flughäfen in Bagdad verwendet. Die Veränderungen in den Hochwasserrückkehrperioden sind in den projizierten Ergebnissen des Klimawandels ersichtlich, und eine Rückkehrperiode wird nur dann über Zeit gültig bleiben, wenn sich die Umweltbedingungen nicht ändern. Dies bedeutet, dass Wiederkehrperioden, die für Planungszwecke verwendet werden, öfter als bisher aktualisiert werden müssen, da die auf Grundlage von Daten der letzten 30 Jahre berechneten Werte innerhalb einer relativ kurzen Zeitspanneunrepräsentativ werden können. Während Wiederkehrperioden bieten nützliche Hinweise für die Planung die Effekte von Überschwemmungen und die damit verbundenen Auswirkungen, müssen aber mit Vorsicht verwendet werden, und Extreme, die öfter eintreten könnten als erwartet, sollten berücksichtigt werden. Im Studienbereich mit getrennten Regenwassersystemen zeigt die Simulation des Regenwasser-Management-Modells, dass sich die Anzahl der Oberflächenhochwasser sowie der Überschwemmungen im Zeitraum 2050e-2080 erhöhen wird. Zukünftige Niederschläge werdensowohl die Hochwasser-Frequenz als auch die Dauer von Überschwemmungen erhöhen. Daher ist die Notwendigkeit offensichtlich, zukünftige Situationen in städtischen Entwässerungssystemen zu berücksichtigen und eine gut geplante Strategie zu haben, um zukünftige Bedingungen zu bewältigen. Die gesamten Auswirkungen auf die Siedlungsentwässerungssyteme aufgrund der Zunahme von intensiven Niederschlagsereignissen müssen angepasst werden. Aus diesem Grund wurden Empfehlungen für die Anpassung an den Klimawandel in der Stadt Hilla vorgeschlagen. Diese wurden durch die Zusammenführung von Informationen aus der Prüfung von fünf Fallstudien, ausgewählt aufgrund der Menge und Qualität der verfügbaren Informationen, erarbeitet,. Die bewerteten Städte sind Seattle (USA), Odense (Dänemark), Teheran (Iran), und Khulna (Bangladesch).:Preface Acknowledgment Abstract Kurzfassung Contents List of Figures List of Tables List of Listing List of Abbreviation Introduction 1.1.

Over the past two decades, northern parts of the United States have experienced extreme heat conditions. Some of the notable heat wave impacts have occurred in Chicago in 1995 with over 600 reported deaths and in Philadelphia in 1993 with over 180 reported deaths. The distribution of extreme heat events in Indianapolis has varied since the year 2000. The Urban Heat Island effect has caused the temperatures to rise unusually high during the summer months. Although the number of reported deaths in Indianapolis is smaller when compared to Chicago and Philadelphia, the heat wave in the year 2010 affected primarily the vulnerable population comprised of the elderly and the lower socio-economic groups. Studying the spatial distribution of high temperatures in the vulnerable areas helps determine not only the extent of the heat affected areas, but also to devise strategies and methods to plan, mitigate, and tackle extreme heat. In addition, examining spatial patterns of vulnerability can aid in development of a heat warning system to alert the populations at risk during extreme heat events. This study focuses on the qualitative and quantitative methods used to measure extreme heat events. Land surface temperatures obtained from the Landsat TM images provide useful means by which the spatial distribution of temperatures can be studied in relation to the temporal changes and socioeconomic vulnerability. The percentile method used, helps to determine the vulnerable areas and their extents. The maximum temperatures measured using LST conversion of the original digital number values of the Landsat TM images is reliable in terms of identifying the heat-affected regions.
