About this book

The production of this Bulletin is a joint effort by the Committees on Hydraulics for Dams and on Dams and Floods to pool resources in producing an overview of the state of the art, latest research and industry developments relating to the subject of blockage of spillways, intakes and bottom outlets by floating debris. The topic is of common interest to both committees as the risks involved can be significant, potentially leading to partial or complete loss of hydraulic functionality or even to dam failure with far reaching public safety and economic consequences. A number of previous bulletins have addressed some of these issues in a range of different ways as outlined in the following paragraphs but none of them was specifically dedicated to this rather complex subject. This Bulletin therefore aims to fill this gap by further improving the awareness of the impact of blockage by floating debris on the economy and safety of reservoir projects and by providing practical guidance on the evaluation and management of the risk of blockage. In particular, it updates the topic by dealing in further detail with the relevant processes within the catchment, in the river basin and through the reservoir, while discussing the various methods and best practice techniques for floating debris characterisation and measures for blockage mitigation. In addition, the Bulletin discusses the uncertainties and residual risks associated with the current practices of dealing with floating debris and highlights areas where further research and development would be required.

La production de ce Bulletin est un effort conjoint des ComitĂ©s sur l'Hydraulique des Barrages et sur les Barrages et les Inondations pour mettre en commun les ressources afin de produire une vue d'ensemble de l'Ă©tat de l'art, des derniĂšres recherches et des dĂ©veloppements industriels relatifs au sujet du blocage des Ă©vacuateurs de crue, des prises d'eau et des vidanges de fond par des dĂ©bris flottants. Le sujet est d'intĂ©rĂȘt commun pour les deux comitĂ©s car les risques encourus peuvent ĂȘtre significatifs, menant potentiellement Ă  une perte partielle ou complĂšte de la fonctionnalitĂ© hydraulique ou mĂȘme Ă  la rupture du barrage avec des consĂ©quences Ă©conomiques et de sĂ»retĂ© publique majeures. Un certain nombre de bulletins prĂ©cĂ©dents ont abordĂ© quelques-unes de ces questions de diffĂ©rentes maniĂšres, comme indiquĂ© dans les paragraphes suivants, mais aucun d'entre eux n'Ă©tait spĂ©cifiquement consacrĂ© Ă  ce sujet plutĂŽt complexe. Le prĂ©sent bulletin vise donc Ă  combler cette lacune en amĂ©liorant la conscience de l'impact du blocage par des dĂ©bris flottants sur l'Ă©conomie et la sĂ»retĂ© des projets de rĂ©servoirs et en fournissant des conseils pratiques sur l'Ă©valuation et la gestion du risque de blocage. En particulier, il met Ă  jour le sujet en traitant plus en dĂ©tail les processus pertinents dans le bassin versant, dans le lit des cours d'eau et Ă  travers le rĂ©servoir, tout en discutant les diffĂ©rentes mĂ©thodes et techniques pour mieux caractĂ©riser les dĂ©bris flottants et les mesures d'attĂ©nuation de leurs effets nĂ©gatifs. En outre, le Bulletin aborde les incertitudes et les risques rĂ©siduels associĂ©s aux pratiques actuelles de traitement des dĂ©bris flottants et met en Ă©vidence les domaines dans lesquels des recherches et des dĂ©veloppements supplĂ©mentaires seraient nĂ©cessaires.
