Risk Levels In Coastal And River Engineering

The cost of ever more freguent floods, landslides and erosion on coastal and fluvial structures is considerable. Through more detailed consideration of the risks and their acceptability, the engineering community could make a 5% saving in the whole-life costs of coastal and fluvial engineering projects, amounting to 250 million annually in the UK alone.This book sets out to provide clear guidance on the process of setting acceptable risk levels. It illustrates the importance of involving all stakeholders in the setting of acceptable risk levels and throughout the deisgn process.

"Contractors involved in construction in, or adjacent to, rivers and estuaries are open to a range of construction risks from working in this environment. - Not only the primary risk of flooding, but significant risk also stems from scour, poor ground conditions, site drainage, plant operation, site access and tidal impact. - The construction works themselves may also have an impact on the river including impact on flood water levels, changes to the local river regime, scour or siltation and effects on navigation and environmental impacts such as pollution. - "This Manual assists in identifying and managing risks in works design and construction. - Guidance is offered on risk assessment and management techniques, along with the identification of typical risk issues likely to be encountered in the river and estuary environment. - It is essential reading for clients, project funders, contractors, consulting engineers (both in design and supervision role), insurers and those interested with the risks associated with river and estuary engineering."--BOOK JACKET.

There is currently an ongoing programme of UK harbour and marina development, encouraged by government investment. This book offers a detailed analysis of the risks involved in coastal engineering.

"Over 200 billion worth of assets are at risk around British rivers and coasts and those risks are likely to increase over the next 100 years due to changes in climate and in society." Sir David King, Government Chief Scientific Adviser This book presents a comprehensive insight into the flooding system, spanning multiple disciplines across different sectors of the flood and flood management professions. It forecasts the manner in which flooding and coastal erosion risks may increase during the 21st century due to climate change.

"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.

Although many theoretical developments have been achieved in recent years, the progress both in understanding and application of risk and reliability analysis in water resources and environmental engineering remains slow. One of the reasons seems to be the lack of training of engineers with phenomena of statistical nature, including optimum cost and benefit decisions under uncertainty. This book presents, in a unified and comprehensive framework, the various aspects of risk and reliability in bothwater quantity and quality problems. The topics covered include uncertainty analysis of water quantity and quality data, stochastic simulation of hydrosystems, decision theory under uncertaintyand case studies. Methods for risk analysis of extremes in hydrology, groundwater clean-up, river and coastal pollution as well as total risk management are presented.

River restoration projects are designed to recreate functional characteristics within a context of physical stability. They tend to focus on the development and application of geomorphic principles for river restoration design. Due to different models obtaining different results on the same problem, incomplete or absent data, and climatic/social/cultural changes, the designers and managers of such projects frequently face high levels of uncertainty. This book will provide a systematic overview of the issues involved in minimizing and coping with uncertainty in river restoration projects. A series of thematic sections will be used to define the various sources of uncertainty in restoration projects and how these show at different points in the life cycle (design, construction and post-construction phases) of restoration projects. The structure of the book will offer a rational theoretical analysis of the problem while providing practical guidance in managing the different sources of uncertainty. A wide range of case studies will be included from Europe, North America and Australasia

Risk and Reliability: Coastal and Hydraulic Engineering sets out the methods which are increasingly being required by Government Agencies for river and sea defence design and flood defence system management. And it shows how to describe uncertainty in the performance of flood and erosion defences.It introduces the key statistical concepts required
