How do braided rivers split into many channels?
Quick Answer
Braided rivers form when a river carries a large sediment load and keeps dropping bars of gravel or sand. The flow divides around these bars into multiple shifting channels.
The Full Story
Braided rivers usually occur where there is lots of loose sediment and variable flow, such as glacial outwash plains or steep mountain valleys. As the river deposits sediment, it creates temporary bars and islands that split the flow into several shallow channels. These channels constantly change after floods because the sediment is easily rearranged. Braided rivers are common in places like New Zealand, Alaska, and the Himalayas.
