The AggDistributionCanal only dispatches on the first timestep. The dispatch method calls the function to route delivery requests upstream from the canal elements for all timesteps. See User Methods for details.

If the No Routing method is selected in the Request Routing category, this object does not dispatch. See No Routing for details.

This dispatch method is only executed when Time Lag request routing is selected in the Request Routing category. See Time Lag for details.
