A bridge is a critical infrastructure which plays a vital role as a transportation link to enhance the connectivity and facilitates the movement for the people, goods, and services. The complex flow pattern created by water flow such as a downflow and horseshoe vortices at the base of the pier leads to the erosion of river bed material. This river bed erosion at the base of the pier forms a scour hole. Therefore, a precise estimation of scour depth at bridge piers is crucial for the safe design of the foundation. This study focuses on predicting the local scour of a hypothetical bridge pier using HEC-RAS 5.0.7 hydraulic tools. In HEC-RAS 5.0.7, 1D simulation is carried out for determining the depth of scour under bridge pier. The study provides a comprehensive approach by integrating hydraulic modeling with empirical scour depth prediction equations within HEC-RAS 5.0.7. The model validation is carried out by comparing the HEC RAS 5.0.7 results with scour depth calculated using different empirical equations in the previous studies of same site. The findings of the study highlight the utility of HEC-RAS as an accessible tool in practice for engineers to assess bridge vulnerability due to scour and provide mitigation design measures for bridges.
