Abstract

This study examined the impact of abutment scour around the concrete Al-Nuhairat Bridge, constructed over the Tigris River in Basrah Governorate. Local scour at bridge abutments is considered a contributing factor to bridge collapse. The study included an analysis of hydraulic variables and their interaction with the soil geological formation, which forms a supporting component in strengthening the abutments. The study also demonstrated the impact of these variables on the scour depth using the Hydraulic Toolbox software. The results were then discussed, clarifying the extent of erosion's impact on the undermining of abutment foundations and its repercussions on the safety and stability of bridges. The study also provided recommendations to mitigate its impact, preserve the sustainability of bridge operations, and take the necessary precautions when preparation future bridge designs, particularly in Basrah Governorate.
