Evaluation of The Local Scour Around Group Piers (Babil Bridge as Case Study)

Saleh I. Khassaf, Saja Sadeq Shakir

The hydraulic bridges are one of the important structures that must be protected from the failure by continuous monitoring. Hence, this study is about the most common causes of bridges failure which is the local scour. In this research Hydrologic Engineering Center River Analysis System (HEC-RAS) program will be used to evaluate local scour around group piers of Babil Bridge in the middle of Iraq. It was found that the HEC-RAS model is a good tool for predicting local scour depth for bridge piers. Where found that the computed scour depth from HEC-RAS program compares well with the observed value. The local scour depth at group piers of Babil Bridge were calculated and found that the piers of the bridge are safe against scouring in the present time because the depth of the maximum local scour is less than the depth of foundation of the bridge.
