ABSTRACT
Bridge datasets in the UK lack geometric data needed to estimate the flood vulnerability of bridges. Therefore, flood quantitative risk assessment (QRA) of these portfolios is impaired. This paper developed design curves to derive arch rise and arch thickness for masonry arch bridges given their maximum span length. The span length was found in all surveyed bridge datasets. The masonry arch bridge type presents the higher flood risk in the UK. This work involved: (i) a search process to identify studies that addressed the lack of bridge data; (ii) the collection of publicly available bridge data for masonry arch bridges over UK rivers; (iii) the fitting of design curves to the collected data; and (iv) the model validation of design curves. Seen statistics metrics, the design curve of arch thickness may supply bridge data. Regarding design curves of arch rise, collected data is too sparse, thus better pre-processing is needed.
