Since this post has such an idiotic answer, I'll explain it. During flooding the force of the current cuts across narrow bends, making the river shift to the new channel. Sometimes obstructions in a river will cause the current to divert and cut a new channel in a different direction around the obstruction. Rivers have also been know to change course because of earthquakes, as did the Mississippi River in 1811 (New Madrid earthquake).
