Abstract: A general analysis, taking advantages of the theory of dimensions has been conducted to delineate the characteristic parameters describing the scouring process due to an obstruction placed in an alluvial channel. The maximum depth of scour was found to be a function of the densimetric sediment Froude number, the relative depth of the flow to the sediment size and the opening ratio of the channel. The functional relationship has been verified using experimental laboratory data of both clear water and live bed scour around a single spur placed perpendicular to the flow direction and empirical formula for the estimation of maximum scour depth has been proposed.
