Notă biografică

The Commission Internationale des Grands Barrages (CIGB) / International Commission on Large Dams (ICOLD) is a non-governmental International Organization which provides a forum for the exchange of knowledge and experience in dam engineering.
The Organization leads the profession in ensuring that dams are built safely, efficiently, economically, and without detrimental effects on the environment. Its original aim was to encourage advances in the planning, design, construction, operation, and maintenance of large dams and their associated civil works, by collecting and disseminating relevant information and by studying related technical questions.
Since the late sixties, focus was put on subjects of current concern such as dam safety, monitoring of performance, reanalysis of older dams and spillways, effects of ageing and environmental impact. More recently, new subjects include cost studies at the planning and construction stages, harnessing international rivers, information for the public at large, and financing.

Descriere

ICOLD Bulletin 147 discusses the upstream and downstream fluvial morphological impacts of reservoir sedimentation and possible mitigation measures. The current state of and possible future sediment deposition in reservoirs have been investigated globally with the aid of the ICOLD Register on Dams.

The global mean reservoir sedimentation rate was found to be 0.8 % of the original storage capacity per year. The book also investigates the impacts of dams on the ecology related to fluvial morphological changes, and guidelines are proposed to mitigate the impacts on the downstream river morphology. Finally an economical model is presented which considers a life cycle approach for reservoir conservation.

Ce CIGB Bulletin 147 traite des impacts morphologiques fluviaux en amont et en aval de la sédimentation des réservoirs et des mesures d'atténuation possibles. L'état actuel et l'avenir possible du dépôt de sédiments dans les réservoirs ont été étudiés à l'échelle mondiale à l'aide du registre des barrages de la CIGB.

Le taux moyen mondial de sédimentation des réservoirs s'est avéré être de 0,8 % de la capacité de stockage initiale par an. Le livre étudie également les impacts des barrages sur l'écologie liés aux changements morphologiques fluviaux, et des directives sont proposées pour atténuer les impacts sur la morphologie des rivières en aval. Enfin, un modèle économique est présenté qui prend en compte une approche de cycle de vie pour la conservation des réservoirs.
