Abstract

Since many communities around the world are facing increasing risks of flooding to bridges due to climate change and increasing urbanization, damage and failure of bridges can lead to casualties and severe economic losses. Thus, it is crucial that transportation networks are resilient to disasters. Despite the large body of literature for seismic and hurricane loss models, a few models and relative taxonomies are available for bridges at risk of flooding. This paper reviews globally available bridge classifications to derive regional flood damage models. The review founds that existing studies mainly classify bridges according to the superstructure material, whereas subclasses consider superstructure construction system and geometry, substructure geometry, joint types, as well as abutment geometry and foundation type. Given that the considered bridge classifications adopt different nomenclatures for the attributes, this study proposes a harmonised taxonomy of 18 attributes for riverine roadway bridges susceptible to floods, and verifies its applicability for three bridge datasets, typical of a UK regional agency. Results show that the considered datasets have data for 13 of the developed 18-attribute taxonomy. Future work should focus either on developing a method to collect missing data or deriving simplified flood damage models which need available data only.
