This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les réseaux d'assainissement en France représentent un considérable patrimoine dont les futurs investissements en terme de maintenance et de réhabilitation seraient de l'ordre de 0.8 à 1.3 milliard d'euros par an pour maintenir une performance de fonctionnement acceptable par les gestionnaires. Ces investissements financiers sont justifiées par un vieillissement indéniable des conduites mais aussi par les exigences formulées par des directives de type Loi sur l'Eau ou NE 752-2. Parce que l'architecture complexe d'un réseau est composée par de nombreux éléments (plusieurs dizaines de milliers de tronçons), des études statistiques et de prise de décision peuvent être envisagées à l'échelle d'un réseau ou d'un bassin versant. Pour cela, les bases de données urbaines doivent être exhaustives (ce qui n'est pas le cas actuellement) et comporter l'information nécessaire pour faire de la gestion du patrimoine. Pour lever les verrous identifiés par la faible quantité d'information contenue dans les bases de données, un support statistiquement représentatif à une base de données réelles "assainissement" est établi en terme de vieillissement des conduites et d'interventions IMR (Inspection, Maintenance et Réhabilitation). Des familles d'indicateurs sont modélisées sur 4 états fournissant le niveau d'alerte en terme d'urgence pour une intervention. Ce travail montre comment à partir d'un tableau de bord structuré, l'utilisation des indicateurs de performance permet de construire des outils (a) de mesure de la performance à différentes échelles, (b) statistiques (Risque Relatifs, Processus de Markov, Fonctions de Survie) capables d'estimer et de prédire l'évolution des performances et (c) financiers représentant la qualité des investissements en terme de performance pour une échéance donnée. Pour programmer les futures interventions en fonction des objectifs de performance du réseau établis par les gestionnaires, on propose d'intégrer une analyse multicritère afin de cibler les ouvrages prioritaires en fonction de la sensibilité des décideurs et du milieu à l'impact d'une défaillance.

Download or read book Aide au diagnostic des r seaux d assainissement written by Christophe Gérard and published by . This book was released on 1999 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les dépôts présents dans les systèmes d’assainissement urbain posent des problèmes multiples d’hydraulique d’exploitation, de confort et de sécurité, d'environnement, de gestion du patrimoine, etc. Leur maîtrise constitue donc un enjeu important pour les gestionnaires de ces systèmes. Les méthodes classiques reposant sur un curage systématique de l'ensemble du linéaire sont coûteuses et les gestionnaires tentent de passer d'une maintenance essentiellement curative à une maintenance préventive, voire corrective. Dans le but d'améliorer ce passage, le travail présenté dans cette recherche consiste à étudier les relations existant entre la structure et le fonctionnement des réseaux d'assainissement, et la localisation des dépôts de matières solides qui y sont transportées. En effet, ces dépôts solides se forment en certains points privilégiés du réseau d'assainissement et sont souvent liés à des causes structurelles, géométriques, fonctionnelles, environnementales, induisant des phénomènes complexes de nature hydraulique, physique, granulométrique, etc. Cette recherche a abouti à la réalisation d'un modèle conceptuel à base de règles expertes paramétrées. Ce modèle permet de prévoir le risque d'envasement de chaque tronçon visitable d'un réseau d'assainissement unitaire en combinant d'une part sa vulnérabilité, c'est à dire sa capacité structurelle à piéger les sédiments s'il en reçoit, et d'autre part la gravité de son exposition à un aléa particulier, c'est à dire la mesure de la plus ou moins grande quantité de sédiments qu'il est susceptible de recevoir. Ce modèle a été construit en s'appuyant sur une démarche itérative combinant une analyse des résultats des études antérieures, des données structurelles disponibles, des mesures de hauteurs d'envasement réalisées sur le réseau du Grand Lyon, et une analyse experte des causes d'envasement identifiées par le personnel d'exploitation de ce même réseau.

Download or read book Water Heritage written by Willem Willems and published by . This book was released on 2017-01-15 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects

This book was released on 2017-11-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union is the second volume in an ongoing exploration of themes and issues relating to astronomical heritage in particular and to science and technology heritage in general. It examines a number of key questions relating to astronomical heritage sites and their potential recognition as World Heritage, attempting to identify what might constitute "outstanding universal value" in relation to astronomy. "Heritage Sites of Astronomy and Archaeoastronomy--Volume 2" represents the culmination of several years' work to address some of the most challenging issues raised in the first ICOMOS-IAU Thematic Study, published in 2010. These include the recognition and preservation of the value of dark skies at both cultural and natural sites and landscapes; balancing archaeoastronomical considerations in the context of broader archaeological and cultural values; the potential for serial nominations; and management issues such as preserving the integrity of astronomical sightlines through the landscape.Its case studies are developed in greater depth than those in volume 1, and generally structured as segments of draft nomination dossiers. They include seven-stone antas (prehistoric dolmens) in Portugal and Spain, the thirteen towers of Chankillo in Peru, the astronomical timing of irrigation in Oman, Pic du Midi de Bigorre Observatory in France, Baikonur Cosmodrome in Kazakhstan, and Aoraki-Mackenzie International Dark Sky Reserve in New Zealand. A case study on Stonehenge, already a World Heritage Site, focuses on preserving the integrity of the solstitial sightlines.As for the first ICOMOS-IAU Thematic Study, a international team of authors including historians, astronomers and heritage professionals is led by Professor Clive Ruggles for the IAU and Professor Michel Cotte for ICOMOS.

Download or read book Bayt Al Aqqad written by Peder Mortensen and published by . This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today Bayt al-'Aqqad is one of 23 buildings in old Damascus which come under the UNESCO World Heritage programme, but when the Danish Institute in Damascus took over the house in 1997 it had been derelict for 50 years and was in a very sorry state indeed. In the following years Danish architects and restorers worked together with Syrian colleagues on an admirable restoration of the house. Step by step new aspects turned up, showing that the building was not only a beautiful house with a long history - the house is founded on the Roman theatre of Herod - but also that it contained fine examples of the most important periods in the architectural history of Damascus. In this lavishly illustrated book the story of the house and its resurrection is told by architects, restorers, archaeologists and historians and it is a must for anybody who has experienced the joy and fascination of Islamic art and architecture.
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.
Download or read book Mapping drought patterns and impacts a global perspective written by Nishadi Eriyagama and published by IWMI. This book was released on 2009 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.

Book excerpt: In recent decades the explosive growth of globalization and regional integration has fuelled parallel growth in multilingual conferences. Although conference interpreting has come of age as a profession, interpreter training programs have had varied success, pointing to the need for an instructional manual which covers the subject comprehensively. This book seeks to fill that need by providing a structured syllabus and an overview of interpretation accompanied by exercises in various aspects of the art. It is meant to serve as a practical guide for interpreters and as a complement to interpreter training programs in the classroom and online, particularly those for students preparing for conference interpreting in international governmental and business settings. This expanded second edition includes additional exercises and provides direct links to a variety of web-based resources and practice speeches, also including additional language combinations.

Download or read book Climate Change Impacts on Freshwater Ecosystems written by Martin Kernan and published by Wiley-Blackwell. This book was released on 2010-09-27 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.

Download or read book Architecture of Counterrevolution written by Samia Henni and published by GTA Verlag. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: After over 120 years of French colonial rule in Algeria, the growing aspirations for independence culminated in the Algerian Revolution of 1954, which lasted until 1962. In order to combat the uprisings, the French civilian and military authorities reorganised the entire territory of the country, swiftly erected new infrastructures and pursued building policies that were ultimately intended to stabilize French dominance in Algeria.The study describes the architectural responses undertaken in the midst of this protracted and bloody armed conflict. It analyses their origins, evolutions and objectives, identifies the actors involved and reveals the underlying design methods.
