Abstract

Infrastructure assets require suitable management and assessment protocols due to age-related deterioration, extreme weather events and climate change impacts. Above ground river crossings are weak links in pipe networks since bank erosion and scour can undermine the integrity of built structures. A simple protocol was developed to assess river bank stability in the vicinity of river pipeline crossings. The Erosion Risk Index (ERI) follows established bank erosion estimation techniques, adapted for users who are not trained geomorphologists. The calculation of ERI is based on the analysis of photographs, acquired during an optimised inspection protocol using a custom app on a ruggedized tablet computer. ERI was tested across Scotland and proved to be adequate for a first order geomorphological assessment, and to provide a classification of crossings according to susceptibility to river bank erosion. ERI is transferable, with appropriate testing, to other infrastructure river crossing networks in the United Kingdom and beyond. The methodology used to develop and test ERI is applicable to the development of other protocols to manage and assess infrastructure assets.
