This book contains the proceedings of the 14th conference of the British Dam Society held at the University of Durham 6-9 September 2006, and covers critical issues relating to Improvements in Reservoir Construction, Operation and Maintenance. It addresses the recent changes to reservoir legislation in England and Wales relating to the enforcement of the Reservoirs Act 1975 and the requirement to prepare flood plans along with the introduction of the Controlled Activities Regulations in Scotland. Following the upgrading of many spillways in the last 30 years, internal erosion is identified as the greatest threat to UK reservoirs so in response to this problem, a number of methods for the early detection of internal erosion are explained. Hydrological and hydraulic issues covered include: a study into the effect of changes in weir crest coefficient with head; computer modelling of the operational systems of reservoirs; and, developments in dam break modelling. Various international projects and case studies are included along with descriptions of grouting works and the desiccation assessment of the puddle clay cores at several reservoirs.
The Interim Guide to Quantitative Risk Assessment of UK Reservoirs was introduced at the Society's 2004 Conference, and this book includes reports that give feedback on its use.show more
