Similitude criteria for flow with sediment transport are derived by normalizing equations of continuity and motion for flow in an alluvial channel. The well‐known Reynolds and Froude numbers are obtained as well as a transport similitude number that prescribes the sediment effects on the inertial, gravitational, and viscous forces acting in the flow system. The Froude number along with a similitude number for the median diameter of the sediment particles is found to specify transport similitude for various flume investigations. A unified correlation of sediment discharge data from numerous laboratory flume studies is developed through the similitude analysis.
