Abstract

Au fil de l’eau, les usagers sont nombreux et entrent en concurrence pour l’appropriation et l’usage de la ressource ; les comportements des riverains à l’égard des gestionnaires de barrages en sont un exemple. Car le partage de l’eau ne va pas de soi, en dépit des nombreuses règles qui le régissent, et il donne souvent lieu à des rivalités d’usages, c’est-à-dire à des affrontements pour son appropriation. Dans cet ouvrage, l’auteur montre comment les usagers parviennent à résoudre ces rivalités et à conclure des arrangements locaux au moyen d’une activation des politiques publiques et des droits de propriété existants. Il s’appuie sur l’idée selon laquelle la forme prise par l’arrangement local dépend étroitement des règles à disposition de chaque usager. Celle-ci est déclinée sous la forme d’hypothèses et est soumise à une comparaison de cas situés dans les bassins versants de la Vesdre en Belgique et du Val de Bagnes en Suisse. La démarche consiste à apprécier le poids relatif des droits de propriété sur l’eau, notamment la propriété foncière, par rapport aux différentes injonctions et interventions publiques visant à influencer le comportement des usagers et à redistribuer l’accès à la ressource. Il apparaît alors que les politiques publiques sont très souvent sollicitées dans les rivalités, y compris par les propriétaires, et qu’elles produisent des effets contrastés sur la répartition des usages de l’eau.

Abstract

New challenges in water systems toward safety, efficiency, reliability, and system flexibility will be fundamental in the near future. In this book, readers can find different approaches that include safety analysis, system efficiency improvements, and new innovative designs. The risk function is a measure of its vulnerability level and security loss. Analyses of transient flows associated with the most dangerous operating conditions, are compulsory to grant system liability in terms of water quantity, quality, and system management. Specific equipment, such as air valves, is used in pressurized water pipes to manage the air inside, associated with the emptying and filling process. Advanced tools are developed toward near-future smart water grids. The water system efficiency and water–energy nexus, through the implementation of suitable pressure control and energy recovery devices, as well as pumped-storage hydropower, provide guidelines toward the most technical and environmental cost-effective solutions. Integrated analysis of water and energy allows more reliable, flexible, and sustainable eco-design projects, reaching better resilience systems. Hydraulic simulators and computational fluid dynamics (CFD), conjugating with field or experimental tests, supported by advanced smart equipment, allow a better design, control, and complex event anticipation occurrence to attain high levels of water system security and efficiency.
