Structures built in or near rivers and other channels can be vulnerable to scour around their foundations. If the depth of scour becomes significant, the stability of the foundations may be endangered, with a consequent risk to the structure of damage or failure. The factors influencing the development of scour are complex and vary according to the type of structure. Scour is not a new phenomenon but the increasing frequency and intensity of extreme weather events over the past 10 years has acted as a salient reminder as to the vulnerability of aged infrastructure assets and that the design basis for more newly constructed works may not be as robust as intended.

This second edition of 'manual on scour at bridges and other hydraulic structures C742', reflects significant advances in the understanding of scour through recent research and improved experience and practices. Emphasis has also been placed on providing specific guidance within the contexts, regulations and legislation of the UK (England, Wales, Scotland and Northern Ireland) and Ireland. It is relevant to scour problems in the UK and worldwide, affecting both new and existing structures.

The manual is available from the ciria website: manual on scour at bridges and other hydraulic structures
