The available scour equations for bridge pier are mostly deterministic in nature, which do not consider uncertainties of various scouring parameters adequately. A reliability-based assessment of bridge pier scour depth is an important step in examining the relationship between safety factor and reliability, which are considered to be key parameters for decision-making in bridge foundation design. In the present study, a reliability model of bridge piers against local scour has been developed using First Order Reliability Method (FORM). The present approach of reliability analysis has been employed for reliability assessment of Black Mount bridge of New Zealand, as a case study. Salient features of the study are described in the present paper.
