Social and economical damages are the most important damages of the bridge failure. Stability problems of such structures against failure and the depth of the abutments are directly related to the amount of the adjusted scour. Economy, reliability and stability have been the main concerns on enhancing the designing of abutment bridges to prevent or reduce embankement scour. In this study a detailed comparison of the researches on scour at abutment bridge are presented including all possible aspects and scour depth estimation formulae. The experimental data for prediction the abutment local scour depth were investigated. Statistical and graphical analysis allow to recommend the most accurate formula in prediction scour depth at the abutment bridges. Availability of additional data and further analysis would allow promoting the bridge abutment design and decreasing the bridges' construction and maintenance cost by increasing the accuracy of the footing depth design. © Maxwell Scientific Organization, 2014.
