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. 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.
