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 sdimentation des rservoirs et des mesures d'attnuation possibles. L'tat actuel et l'avenir possible du dpt de sdiments dans les rservoirs ont t tudis l'chelle mondiale l'aide du registre des barrages de la CIGB. Le taux moyen mondial de sdimentation des rservoirs s'est avr tre de 0,8 % de la capacit de stockage initiale par an. Le livre tudie galement les impacts des barrages sur l'cologie lis aux changements morphologiques fluviaux, et des directives sont proposes pour attnuer les impacts sur la morphologie des rivires en aval. Enfin, un modle conomique est prsent qui prend en compte une approche de cycle de vie pour la conservation des rservoirs.
