When two rivers merge, such as the Missouri and the Mississippi, they continue downstream as the Mississippi. The same is true for almost all confluences - the Wisconsin River ends when it flows into the Mississippi River, The Wabash joins the Ohio and they flow on as the Ohio. However, in Pittsburg, Pennsylvania, the Allegheny River and the Monongahela River come together to form the Ohio River, with neither name carrying on downstream - hence the name "Three Rivers Stadium" at that point. Is there rule or a pattern for this? Is it the similarity of their sizes or the layout of the land or is there some other reason that I am unable to guess why they take on a new name at this point?
