A natural levee on the main river prevents joining. When a river floods, sediment is deposited along the banks and builds up over time, creating natural levees. These levees can prevent smaller tributary streams from joining with the main river. This is the case with many Yazoo tributaries in Mississippi, where the Mississippi River has built up natural levees that block the joining of smaller streams.
