Utilizing the river floodplain for the purpose of urban landscaping and eco-tourism benefit could greatly reduce the river width that would eventually increase flood intensity. This could possibly weaken the bridge foundation that increase the probability of bridge failures due to scour. The main objective of this study is to evaluate scour predictive formulae at a protruding abutment bridge in the compound channel, using Multiple Testing Problem (MTP) in a geometrical model of an Integral Abutment Bridge (IAB). The results of the MTP and graphical comparison yield satisfactory predictive formula. Findings of the current study can help determining maximum scour depth as an essential component of footing design to optimize both construction and maintenance costs. © 2017, Korean Society of Civil Engineers and Springer-Verlag Berlin Heidelberg.
