dc.description.abstractAccording to (Wang, Yu, & Liang, 2017) , scour of sediments around bridge foundations by the stream is the most significant contributing factor for bridge failures. The scour failures tend to occur without prior warning and have led to fatalities and economic loss every year. Flowing water can affect bridges by eroding streambed or bank material. This scour can expose bridge elements, compromising bridge stability and safety and leading to bridge failure. Bridges with foundations that are unstable for calculated and/ or observed scour conditions are termed scour-critical bridges. This study evaluated the scour condition of Bunoga bridge on river Mpanga using the Froehlich’s Abutment scour equation (method) and HIRE Abutment scour equation, used to determine whether the bridge and its elements are scour critical or not and results of different methods were assessed to ascertain which was more suitable for Abutment scour evaluation on the case study and its specific characteritics. After a review of findings and analysis, it was concluded that the Froehlich’s Abutment scour equation was more accurate in Abutment scour analysis than the HIRE Abutment scour equation on the case study. Chapter 1 introduces the bridge scour situation, problem statement, objectives of the study, justification and scope of the study. Chapter 2 gives a moderately detailed description of the different forms of bridge scour and methods of determining and evaluating bridge scour depths and computations necessary for arriving at conclusive results. Chapter 3 gives the methodology that was used to evaluate bridge scour. Chapter 4 gives the findings and analysis of the study. Chapter 5 gives the conclusions and recommendations of the study.en_US
