Book Synopsis Systèmes alternatifs de gestion des eaux pluviales by : Robin Garnier
Download or read book Systèmes alternatifs de gestion des eaux pluviales written by Robin Garnier and published by . This book was released on 2020 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: La gestion des RUTP est un enjeu majeur des collectivités, tant d'un point de vue des quantités d'eau ruisselées toujours plus importantes, que suivant un objectif de qualité pour les eaux superficielles en accord avec les exigences de la Directive Cadre européenne sur l'Eau. Pour ce faire, les municipalités se munissent d'ouvrages de gestion des eaux pluviales alternatifs (aux réseaux) afin de réguler les flux d'eau ou de redonner de la perméabilité aux sols urbains en infiltrant les eaux pluviales soit à grande échelle (bassins de retenue ou d'infiltration) ou à plus petite échelle directement à la source du ruissellement (systèmes de gestion à la source). Une documentation fournie existe sur la qualité des RUTP concernant les polluants globaux (MES, DCO, nutriments...), les métaux et les HAPs. Ces deux dernières familles de substances sont de la pollution des eaux pluviales et nombre d'études ont caractérisé leur traitement par des techniques alternatives. Peu ou pas d'études ne s'intéressent en revanche à une gamme plus vaste de micropolluants prioritaires tels que les pesticides, les alkylphénols ou encore les retardateurs de flamme bromés. La présente recherche a pour objectif de contribuer à pallier ce manque de connaissances en apportant des résultats sur la caractérisation qualitative in situ des eaux liées à deux types de dispositifs (centralisés et décentralisés) pour 59 micropolluants. Quatre sites expérimentaux ont ainsi été choisis pour les campagnes de mesure à l'exutoire de i) un bassin de rétention centralisé, et trois sites de gestion à la source drainant des parkings résidentiels : ii) une chaussée à structure réservoir, iii) une tranchée d'infiltration en graves, et iv) une noue végétalisée. 59 micropolluants de cinq familles différentes (métaux, HAPs, pesticides, alkylphénols, PBDEs) ont ainsi été analysés pour une douzaine d'évènements pluvieux. Les flux d'eau de plus de 100 évènements ont été étudiés grâce à des dispositifs de métrologie et de prélèvement spécialement développés afin de pouvoir mesurer l'ensemble de la gamme de débits observables à l'exutoire des ouvrages décentralisés. Il a été constaté que si les métaux et les HAPs sont les polluants les plus particulaires et les plus présents dans les eaux, ce sont aussi les mieux traités par les ouvrages, notamment les systèmes à la source dont la filtration se révèle plus efficace que la décantation du bassin centralisé. Les autres familles de micropolluants ont montré une spéciation plus aléatoire et une plus grande propension à être capté par la noue et la tranchée que par les autres ouvrages. Les sites à la source montrent un meilleur potentiel de traitement des eaux pluviales du fait de leur pouvoir de filtration intrinsèque par rapport au bassin centralisé, mais la noue et la tranchée se démarquent également par une rétention d'eau très importante qui accentue leur action épuratoire en termes de quantité totale en micropolluants rejetés dans les milieux.

Book excerpt: In almost every country of the developing world, the most active builders are squatters, creating complex local economies with high rises, shopping strips, banks, and self-government. As they invent new social structures, Neuwirth argues, squatters are at the forefront of the worldwide movement to develop new visions of what constitutes property and community.

Book Synopsis Cambridge Handbook of Engineering Education Research by : Aditya Johri
Download or read book Cambridge Handbook of Engineering Education Research written by Aditya Johri and published by Cambridge University Press. This book was released on 2014-02-10 with total page 1124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.
Download or read book Engineering written by Unesco and published by UNESCO. This book was released on 2010-01-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews engineering's importance to human, economic, social and cultural development and in addressing the UN Millennium Development Goals. Engineering tends to be viewed as a national issue, but engineering knowledge, companies, conferences and journals, all demonstrate that it is as international as science. The report reviews the role of engineering in development, and covers issues including poverty reduction, sustainable development, climate change mitigation and adaptation. It presents the various fields of engineering around the world and is intended to identify issues and challenges facing engineering, promote better understanding of engineering and its role, and highlight ways of making engineering more attractive to young people, especially women.--Publisher's description.

Book Synopsis Protected Area Management by : Barbara Sladonja
Download or read book Protected Area Management written by Barbara Sladonja and published by BoD – Books on Demand. This book was released on 2012-08-08 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protected areas are at the base of the most national and international conservation strategies. Due to the many unpredictable elements in ecology matters, each protected area requires a case-specific set of guidelines but a common issue is how to cope with human interaction. The management of protected areas is replete with challenges and the only way to gain understanding and achieve greater management possibilities is to exchange experiences and knowledge. Environmental managers are aware of that and together with scientists are looking for more modern and better solutions, both with respect to natural resources and human interactions in many issues regarding nature protection. This publication presents reviews and research results on protected areas management, as well as 12 case studies derived from around the world with the aim of improving management effectiveness of the protected areas.

Book Synopsis Routledge International Handbook of Ignorance Studies by : Matthias Gross
Download or read book Routledge International Handbook of Ignorance Studies written by Matthias Gross and published by Routledge. This book was released on 2015-05-15 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.
