Abstract
The flood events that occurred in 2011 and 2013 in Queensland are notable for their devastating outcomes and damages to critical road structures. Bridges are necessary for the local community to travel and provide disaster relief during times of need. Therefore, it is important to identify methods that prevent bridge scour.
To identify these countermeasures, a literature review of critical infrastructure scour prevention method was conducted. Methods that are appropriate were then analysed using the hydraulics software HEC-RAS. The Tenthill Creek Bridge was chosen as the framework of the analysis. Bridge scour depths were modelled and each method was compared. Combined with the HEC-RAS analysis, the feasibility analysis shows that a combination of collaring, riprap and wing walls is the most cost effective in decreasing the scour depths at piers and abutments.
