Stormwater Adaptive Resilience and the Assessment of Rotterdam’s Urban Water System / Adaptiv resiliens i dagvatten och bedömning av Rotterdams stadsvattensystemXiong, Yi January 2021 (has links)
As the global climate gets warmer, local extreme weather becomes more frequent, and it becomes more and more difficult to accurately predict the occurrence of extreme rainfall. At the same time, the threat and destructiveness of stormwater weather to urban water systems and cities are also increasing due to the continuous advancement of urbanization, the continuous gathering of urban population and the increasingly obvious urban heat island effect.Since it was first proposed, resilience thinking has become a very important idea in urban planning and research. With the continuous development of resilience thinking, its concept and connotation are also constantly improved and developed. It has developed from a single state of resilience at the beginning to cover all aspects of social, economic and ecological issues.This research aims to find the resilience level of the urban water system of Rotterdam, and find some typical cases of Rotterdam’s experience for other cities to learn. Based on the resilience thinking, this study takes Rotterdam as an example to comprehensively evaluate the resilience of the urban water system under stormwater disaster and urban flood and waterlogging. The first part of this thesis first introduces the urban water system, resilience thinking and other concept which this thesis use. In the second part, this thesis mainly introduced the specific analytical method and analytical framework, namely ASPIRE model. The third part will combine the analysis model with the example of Rotterdam, and comprehensively analyze the stormwater adaptive resilience of the urban water system. In the fourth part of this thesis, three engineering examples of Rotterdam which worthy of promotion and learning are introduced and summarized in detail. The last part of this thesis is the discussion and conclusion. Through this study, it is found that the urban water system of Rotterdam has high stormwater adaptive resilience and Rotterdam has many successful experiences which can be learned by other cities.

An Approach To Urban River Rehabilitation For Coexistence Of River And Its Respective City: Porsuk River Case And City Of EskisehirSimsek, Gul 01 July 2011 (has links) (PDF)
All living things mostly the humans, as builders of civilizations, have always been in intrinsic bonds with water. This interaction between water (oceans, seas, lakes, rivers etc.) and settlements has existed since ancient civilizations. Among water resources, &lsquo / flowing waters&rsquo / such as rivers, streams, creeks, etc. have a prominent role as they are the lifeblood of most cities in terms of providing transportation, security, energy, irrigation, commerce, and recreation. By the late 19th century, developments of terrestrial transportation modes diminished the magnetism of rivers and riverfronts, and growing industries led to the deterioration of rivers. Owing to these reasons, along with many others, they turned into sewage channels, were covered up, and became water scopes detached from the urban life. Particularly since the 1970s, with more attention given to sustainability of resources, a greater awareness has grown of the vital role of urban rivers as a resource for humans and a lifeline for cities. After being neglected for decades, urban rivers have started to be rehabilitated to solve the related problems. The new approach to urban river rehabilitation beyond classical practices that aim at recovering the physical conditions of rivers has come to the fore to address the problems comprehensively. Instead of independent and one-dimensional practices, the urban rivers have become to be seen as a vital part of urban water system and of the city itself.
While rehabilitating urban rivers, recovering river health can be ensured provided that the entire urban water ecosystem is taken into consideration. The ecocity approach is one of the major new approaches that geared toward achieving a healthy city, and sustainability of water system is the significant goal within this approach. In this regard, the thesis first asserts that the ecocity criteria are likely to give way to a more sustainable future for urban rivers. Besides being a part of the ecosystem, urban rivers have transformed together with the surrounding built environment throughout the history of cities. Significant focal elements of the urban pattern, urban rivers should be dealt with other urban focal points, with the introduced concept of river-city integration, which is proposed as the second assertion of the thesis. In this respect, the study attempts to investigate urban rivers and their rehabilitation in relation with both the ecocity approach, and the river-city integration concept. The research methodology in the present study involves comparative anaysis of best practices and case study analysis. Porsuk River and the city of Eskisehir, which the river passes through, were selected as a case for empirical study. Criteria sets that determined within the frames of ecocity and river-city integration, and the testing of the criteria in the case area offers an opportunity to contribute to literature of river and city coexistence.

Previous issue date: 2002-03-31 / Financiadora de Estudos e Projetos / The sustainable development concept has been used as a basic framework of urban
planning processes. Due to its subjective components there were cases where the
sustainability principles were used as marketing instruments, instead of an objective
planning tool. As an attempt to reverse this situation the group for Sustainable and
Strategic Urban Planning, from the São Carlos Federal University, studies way to apply
sustainable development principles in the assessment and analysis of urban projects.
In this thesis it was created a Method, which can be used in the evaluation of
components of urban water system projects (water supply, wastewater collection and
treatment, urban drainage, etc.). The Method is based on defined parameters and
uses descriptive lists, flowcharts and interaction matrices to indicate sustainability
tendencies (positive, negative or neutral). This model was applied in five different
projects, which indicated some adjustments. The model was considered simple and
effective. Another advantage of the Method is its modular character: new information
and tools can be added, in order to obtain more complex analysis. Besides that, it can
be used to evaluate the planning or performance of other sustainable systems. / O conceito de sustentabilidade tem sido proposto e utilizado como referência para o
planejamento das atividades humanas e a democratização de decisões na sociedade.
Entretanto, nem sempre é abordado de forma objetiva, e sua característica subjetiva
permite que, muitas vezes, seja usado apenas como instrumento de propaganda.
Visando contribuir para alterar esse quadro, vêm sendo desenvolvidos, pelo Grupo de
Planejamento Estratégico e Sustentável do Meio Urbano (PESMU) da UFSCar, estudos
para a obtenção de métodos que incorporem a questão da sustentabilidade na análise
e avaliação de projetos no contexto urbano.
No presente trabalho, é feita a avaliação de um Método desenvolvido para análise da
sustentabilidade ambiental em projetos de sistemas urbanos de água (abastecimento,
esgotamento, drenagem). Baseando-se em variáveis de controle previamente
definidas, o Método faz uso de fichas de caracterização, fluxogramas e matriz de
interação utilizadas em conjunto, apontando tendências favoráveis, desfavoráveis ou
neutras de sustentabilidade ambiental. Foram feitas as aplicações práticas do Método
em diferentes tipos de projetos e, a partir de uma análise dos resultados, foram
propostos ajustes no mesmo. A utilização do Método mostrou-se viável, mesmo com
algumas limitações detectadas. Entretanto, podem vir a ser incorporadas novas
informações e ferramentas mais complexas, ampliando suas possibilidades de
aplicação, principalmente para o planejamento de sistemas e o acompanhamento de
seu desempenho, além de poder ser aplicado nas demais dimensões da
sustentabilidade.

Assessing the environmental impacts of a complex urban water system based on the life cycle assessment framework : development of a versatile model and advanced water deprivation indicators / Évaluation des impacts environnementaux d'un système d'eau urbain complexe dans le cadre de l'analyse du cycle de vie (ACV) - Développement d'un modèle polyvalent et d'indicateurs de privation d'eau avancés : développement d'un modèle polyvalent et d'indicateurs de privation d'eau avancésLoubet, Philippe 27 November 2014 (has links)
La gestion intégrée de l'eau à l'échelle des grandes villes est un réel défi. Cependant, la quantification des flux et des impacts environnementaux liés à l'utilisation de l'eau n'est pas encore suffisamment développée. Dans ce contexte, la question de recherche de la thèse est: "comment modéliser le système d'eau urbain complexe d'une mégapole pour l'évaluation de ses impacts sur l'environnement et des services fournis aux usagers de l'eau, dans le cadre de l'analyse du cycle de vie (ACV)?" Le cœur de la thèse est le développement d'un cadre général définissant les flux d'eau et les impacts environnementaux associés aux trois composants principaux du système d'eau urbain, à savoir, les technologies de l'eau, les usagers de l'eau et les ressources en eau. Le modèle proposé de système d'eau urbain (nommé WaLA) se construit à travers une approche modulaire permettant l'interopérabilité des trois composants. Le modèle fournit des indicateurs d'impacts et de services rendus qui peuvent être utiles aux décideurs et aux parties prenantes. Il simplifie l'évaluation des scénarios et diminue la complexité du système tout en assurant sa bonne représentation du point de vue de l'ACV. En plus de cet objectif principal, la thèse vise à raffiner les indicateurs d'impact sur la privation d'eau afin qu'ils soient pertinents pour les systèmes d'eau urbains. Une méthode qui permet d'évaluer la privation d'eau à l'échelle du sous bassin versant en intégrant les effets en aval a ainsi été développée. Cette méthode permet de différencier les impacts selon les points de prélèvements et de rejets dans un même bassin versant. Enfin, le modèle WaLA et les indicateurs associés sont mis en œuvre pour évaluer les impacts environnementaux du système d'eau urbain de la banlieue parisienne (périmètre du Syndicat des Eaux d'Ile-de-France). L'intérêt et l'applicabilité du modèle pour évaluer et comparer des scénarios actuels et prévisionnels sont ainsi démontrés. / To improve water management at the scale of large cities is a real challenge. However, the quantification of flows and environmental impacts linked to water use are not yet sufficiently developed. This is the objective of the thesis: “how to model complex urban water system of a megacity for assessing its environmental impacts in relation to the provided services to water users, within the life cycle assessment (LCA) framework?” The core of the thesis is the development of a generic framework defining water flows and environmental impacts associated with 3 categories of items – i.e., water technologies, water users and water resources – from a LCA point of view. The UWS model (termed WaLA) is built through a modular approach allowing the interoperation of these three components in an integrated way. The model provides indicators of impacts on services which may be useful to decision makers and stakeholders. It simplifies the evaluation of forecasting scenarios and decreases the complexity of the urban water system while ensuring its good representation from a LCA perspective. In addition to this main objective, the thesis also aims at refining water use impact indicators at a relevant scale for UWS. A methodology that assesses water deprivation at the sub-river basin scale in life cycle impact assessment (LCIA) integrating downstream cascade effects has been developed. It allows differentiating the withdrawal and release locations within a same river basin. The WaLA model and its associated indicators are applied to assess the environmental impacts of the water system of a Paris suburban area (perimeter of Syndicat des Eaux d'Île-de-France). It shows the interest and the applicability of the model for assessing and comparing baseline and forecasting scenarios.

Modernisation et soutenabilité des systèmes hydriques urbains en Europe : une approche néoinstitutionnaliste des régimes de ressources / Modernisation and sustainability of urban water systems : a neoinstititionalist approach of resources regimesBolognesi, Thomas 31 October 2013 (has links)
Cette thèse a pour objet la modernisation des Systèmes Hydriques Urbains de l'Europe des XV (SHUE). Débutant à la fin des années 1990, ce processus de rerégulation des SHUE opère une transformation du cadre réglementaire européen de la gestion de l'eau. Il vise une amélioration du fonctionnement de la gouvernance afin, notamment, d'imprimer une trajectoire soutenable aux SHUE. Or, les bilans intermédiaires s'avèrent mitigés et mettent en avant un besoin de caractérisation et d'explication analytiques de la modernisation des SHUE, afin d'en cerner les effets non anticipés. Par conséquent, la thèse aborde les effets de la modernisation des SHUE dans ses dimensions organisationnelle et soutenable. L'objectif de la thèse consiste à fournir une interprétation des impacts de la modernisation sur la structure de la gouvernance des SHUE et sur son efficacité dans une perspective de soutenabilité. Ancrée dans une approche d'économie institutionnelle, la démarche adoptée compare les modèles allemand, français et anglais et s'organise en deux temps. Le premier temps relève de l'observation empirique. Les phénomènes caractérisant la modernisation sont identifiés et formulés sous la forme de faits stylisés. Le second temps explique théoriquement ces phénomènes. Au regard des apports et limites des différents institutionnalismes, il est choisi de mobiliser le courant néoinstitutionnaliste pour rendre compte des aspects organisationnels et l'approche par les Régimes institutionnels de ressources pour traiter de la dimension soutenable de la modernisation des SHUE. Cette thèse soutient que la modernisation entraîne une mutation des modalités de coordination des SHUE, tout en intensifiant et polarisant les problèmes de soutenabilité autour du pilier économique. Au niveau organisationnel, nous mettons en évidence que, d'une part, la modernisation tend à dépolitiser les SHUE et que, d'autre part, le degré d'intégration de ses principes dans un SHUE est positivement corrélé à une dynamique socio-institutionnelle résiliente. Ces deux phénomènes résultent principalement d'une hybridation des arrangements institutionnels en direction du pôle marché. Le changement des formes contractuelles et l'atténuation des droits de propriété au sein des SHUE réduisent le contrôle direct de l'Etat et augmentent la capacité d'adaptation rapide des acteurs. A propos du potentiel de soutenabilité, un manque de cohérence dans le développement de la rerégulation des SHUE explique les perspectives relativement pessimistes. Nous montrons que ce paradoxe manifeste une incapacité intrinsèque de la modernisation à maximiser le potentiel de soutenabilité des SHUE. Si le développement de la réglementation est censé améliorer la qualité de la gouvernance, dans notre cas, elle s'accompagne d'un accroissement mécanique de coûts de coordination entravant l'atteinte d'une trajectoire soutenable. / This PhD dissertation focuses on the modernization of the urban water systems in Europe (UWSE). Since the end of the 1990's, this reregulation of the UWSE has transformed the European regulatory framework of water management. It is driven by two mains objectives: improving of the governance process and implementing a sustainable path for the UWSE. Present day, intermediate assessments highlight a need for analytical characterization and explanation of the UWSE's modernization, in order to home in on the unanticipated effects. Thus, the PhD thesis analyses the effects of the UWSE's modernization in its organizational and sustainable dimensions. The goal of the PhD is to provide an interpretation of the modernization impacts on the UWSE governance structure and on the efficiency of the reforms from a sustainability point a of view. Rooted in an institutional economics approach, our methodology consists in a comparative analysis of the German, French and English models of the UWSE. Two phases structure this methodology. The first focuses on empirical observation. The phenomena that characterize the modernization are identified and enunciated as stylized facts. The second phase theoretically explains these phenomena. Regarding the contributions and limits of the different institutionalisms, we choose to mobilize the New institutional economics here to deal with the organizational aspects and Institutional resources regimes to address the sustainable dimension of the UWSE's modernization. We argue that the modernization of the UWSE involves a transformation of their coordination modalities, at the same time; it is intensifying and it leads the sustainability problems to focus on the economic pillar. At the organizational level, we support that, on the one hand, modernization tends to depoliticize UWSE and that, on the other hand, the degree of integration of its principles in the UWSE is positively correlated with a resilient socio-institutional dynamics. These two phenomena ensue essentially from a hybridation of the institutional arrangements in the direction of the market pole. In the UWSE, the change of the contractual forms and the attenuation of the property rights lead to a reduction of the State's direct control and to an augmentation of the actors' ability to adapt quickly. Regarding the potential of sustainability, a lack of coherence in reregulation of UWSE accounts for the pessimistic prospects. We show a paradox which manifests itself in the intrinsic inability of the modernization to maximize the UWSE's potential of sustainability. If the development of the regulation is supposed to improve the governance quality, in this case, it comes with a mechanical increase of the costs of coordination which hampers the achievement of a sustainable path.
