An Engineering Guide To Seismic Risk To Dams In The United Kingdom

This guide assesses the seriousness of seismic risk and proposes criteria for earthquake safety evaluation of existing UK dams. It relates specifically to the safety of UK dams and reservoirs under seismic loading although it should also be useful in the design of new dams. The guide is relevant to all forms of dam construction.

Part 1. Conceptual and planning practice for reservoirs - Introduction and philosophy of approach - Objectives - Selection of potential dam sites and conceptual schemes - Investigation of selected sites and geological studies - Hydraulic studies - Hydrological studies - Spillways - River diversion during construction - Seismic loading Part 2. Development practice for reservoirs - Water conduits for reservoirs - Tunnelling problems and excavation of shafts - Electro-mechanical equipment and controls - Environmental considerations - Costs and benefits - Efficient management for irrigation - Small hydropower - Safety and inspection of reservoirs - Operation and maintenance, monitoring and inspection

"This interim guide to quantitative risk assessment for UK reservoirs provides a tool for the management of reservoir safety by experienced dam professionals. It comprises a screening level assessment of the risk of failure of a dam, i.e. the uncontrolled sudden large release of water from the reservoir it retains." "The guide is in the form of a Microsoft Excel workbook with proforma calculations, and accompanying text. It is intended to form part of either a periodic safety review or a portfolio risk assessment, where application of this guide identifies potential concerns a more detailed assessment is likely to be appropriate."--Résumé de l'éditeur.

Presents proceedings the 13th Conference of the British Dam Society held at the University of Kent, June 2004. These papers include discussion on the benefits that reservoirs can provide in terms of water supply and recreation, the environmental impact they can have, and the use of geomembranes to provide water tightness.

A guide for engineers and others responsible for the safety of embankment dams. It includes a brief history of UK dams, legal requirements, design, construction methods and materials, procedures and/or checklists for surveillance and investigation, instrumentation and monitoring, remedial works and alterations, and rapid draw-down.

This volume is the Proceedings from the 12th International Conference organised by the British Dam Society in September 2002.Reservoir safety is the key theme with many papers on the performance and rehabilitation of dams. The evolution of reservoirs in Ireland and the development of safety legislation in the UK are described. Risk assessment features in a number of papers as a method of assessing the safety of reservoirs. Several papers address the seismic assessment of dams and structures.

This book offers the guidelines on long-term confinement of fine particulate waste products in a safe and environmentally acceptable location. It seeks to present the state of the art, drawing on combined experience from within the European Union (EU), on good international practice where relevant and on lessons learnt from recent untoward incidents. These guidelines have been developed in parallel with the development of the European Standard on Earthworks (prEN 16907) and the contents have been influenced by the well-publicised need for guidance to all stakeholders on both technical and regulatory aspects of the permitting, design and construction of extractive waste facilities in Europe. The Extractive Waste Directive (EWD) imposes a duty on all operators and regulators to ensure the competent design, operation and closure of such facilities. However, though some guidance has been published on a limited number of related technical elements, the relevance of these contributions has been diminished by the lack of an integrated approach. It is now evident to both regulatory bodies and operators alike that a unified and comprehensive document providing guidance to all stakeholders is required if the future of mining within the EU is to be assured and further untoward incidents avoided. These guidelines seek to address all technical stages of the development of a hydraulic fill project in the context of the EWD, with an emphasis on waste and facility characterisation and on the risk-based assessments which underwrite them. They are intended for use by all stakeholders involved in those European industries which involve the generation, transport and storage of fine particulate waste products requiring long-term confinement in a safe, stable and environmentally acceptable location.
