does ebb and flow occur when two rivers meet?

when two rivers with different speeds converge, the faster river blocks the water of the slower one. the slower river swells up and at some point pushes back the water of the faster river, and so forth. thus the height of the water alternates regularly, just as it does in ebb and flow. each time the relationship between the rivers, in their forward and backward motion, approaches an equilibrium, the water-level of the confluent canal downstream of the two rivers sinks as well.
