My understanding is it is just a difference in terms. As many times you will find the outflow is same as discharge. But outflow can take into account other sources of water other than what is discharged. I am sure someone will articulate it better than me. But discharge usually means what is being controlled and outflow is the flow of the river that might have other water input besides what is being discharged. I am sure others will weigh in on this.
