Most of the hydraulic failures of bridges occur due to the formation of the scour hole at the corner of the abutment and in front of the pier. When the scour hole is more, the grip length of the foundation of the abutment and pier reduces causing destabilization of the bridge as a whole. Scour studies around the abutments and pier in clay bed attracts more studies due to the swell–shrink characteristics of the soil. In this study, an attempt is made to conduct a series of scour studies for clayey soil with three densities, i.e. 1.15, 1.23 and 1.37 g/cc and four abutment sizes, i.e. 2, 3, 4 and 5 cm. Based on the test results, the effect of the width of abutment on the maximum scour depth at the end of 600 min of flow run was analysed. It is found that the maximum scour depth increases as the width of abutment increases and reduces as density increases. The rate of scour reduces with time and when the time parameter exceeds 4, it approaches to zero asymptotically.
