Time evolution of the maximum scour depth around piers up to peak value of the design flow is required for safe foundation design of bridges crossing alluvial rivers. This study deals with an experimental work conducted to investigate the surface characteristics of scour-holes around dual piers aligned with the flow direction under clear water conditions with uniform bed material. Experiments are conducted using different sizes of identical cylindrical dual piers for different spacing and flow intensities. Eventually a scour-prediction equation is developed to determine the temporal variation of maximum clear water scour depth. In the test ranges of the experiments, the results of the proposed equation are found to be in relatively good agreement with the experimental results.
