In extreme circumstances, it can lead to the bridge's structural collapse. Despite efforts to reduce the scour's unfavorable effects in the vicinity of bridge foundations, this issue remains a significant challenge. Many uncertainties affect the design process of bridge foundations, namely the associated hydrological and hydraulic parameters. Past and recent flood records strengthen bridges' vulnerability by reducing scouring estimation uncertainties. Therefore, the present study applies a semi-quantitative methodology of scour risk assessmentto a Portuguese bridge case study, accounting for those uncertainties. The risk-based methodology comprises three main steps towards the assignment of the bridge's scour risk rating. The methodology constitutes a potential key tool for risk management activities, assisting bridge's owners and managers in decision-making.&lt;\/p&gt;<\/jats:p>","DOI":"10.2749\/prague.2022.1366","type":"proceedings-article","created":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T15:28:13Z","timestamp":1654097293000},"page":"1366-1373","source":"Crossref","is-referenced-by-count":3,"title":["Assessment of Scour Risk in Hydraulic Infrastructures.
