Are vulnerable to scour around their foundations. Scour can compromise the stability of the structure leading to a significant risk of damage or even failure. Experts from HR Wallingford have helped to update guidance relating to scour, providing engineers with a comprehensive manual delivering the latest approaches in this field. HR Wallingford led the development of the first Manual on scour at bridges and other hydraulic structures. The manual has been an indispensable reference for river engineers and asset managers since its publication in 2002. Now, more than a decade on, HR Wallingford’s fluvial scour experts have played an important role in the manual’s update.
Launched in April 2015, the second edition of Manual on scour at bridges and other hydraulic structures incorporates the latest advances made in the understanding and application of the science, engineering and hydraulics of scour at bridge sites, weirs, culverts, pipeline crossings and other structures. Manuela Escarameia and Marta Roca led HR Wallingford’s input in to the manual. Manuela Escarameia said: “The aim of the update was to ensure that the guidance in the manual reflects the state of the art in fluvial scour engineering and provides guidance on scour risk assessment for bridge asset managers in the UK and Ireland. “We’ve applied HR Wallingford’s expertise in this field, which is continually enhanced through our UK and international consultancy projects, site experience and a comprehensive programme of self-funded research into scour issues in the fluvial, estuarine and marine environments. Our at our headquarters in Wallingford, UK, are a unique asset for the development of new design guidance and for the validation and optimisation of existing and new schemes.

May Publisher: Construction Industry Research & Information Association (CIRIA) Category: Civil Engineering Language: English Page: 226 ISBN: ISBN13: 513 Description: Structures built in or near rivers and other channels can be vulnerable to scour around their foundations. If the depth of the scour becomes significant, the stability of the foundations may be endangered, with a consequent risk of damage or failure of the structure. In the past 15 years, there have been several bridge failures, resulting in transport disruption, economic loss and, on occasion, loss of life.
Some of these failures are included in the manual's summary case studies. The factors influencing scour are complex and vary according to the type of structure.
Protection works for preventing scour need to be designed to withstand the flow forces imposed on them and have to be practicable to build and install, while minimising adverse environmental effects. The manual therefore considers scour processes, estimating and assessing scour, protective measures, monitoring, environmental factors, risk assessments, and cost and benefit analyses. This manual is intended for engineers engaged in the design, construction, operation and maintenance of structures in the water environment that may be subject to scour of erodible beds or banks.
It is equally relevant to UK and worldwide scour problems, and to new as well as existing structures. Download this book.
