confluence
The term used to describe one river emptying into another is "tributary." A tributary is a smaller stream or river that flows into a larger one, contributing its water to the main river system. The point where the tributary joins the larger river is called the confluence.
The base level of a river is the lowest place where it can flow, generally it's mouth. Therefore if a river or stream flows into another river, then the first river's base level is the point where it joins the other river.
