The routing of a bed material load through a branching irrigation canal system in such a way as to insure sediment discharge equilibrium is considered. All the sediment entering the system is disposed of with the water. It is shown that the system equilibrium can be more easily achieved if smaller sediment concentrations are allocated to irrigation diversions from smaller channels. Also, an approximate numerical model for predicting the bed material load from farm turnouts is presented.
