1. What is the scientific name?Fluvial geomorphology
2. What is the key morphological features?Multiple, shifting channels, mid-channel bars, and islands
3. Why do braided rivers split into many channels?The river splits when it carries more sand and gravel than it can carry in one channel. The extra material builds up into bars, forcing the water to flow around them and create new channels.
4. Where can braided rivers be found?Braided rivers are common where there is lots of sediment and changing water flow, such as glacial meltwater plains, mountain streams that spread onto flat land, and river deltas. Examples are the Brahmaputra in Asia, the Platte in the U.S., and rivers in Iceland and New Zealand.

Avulsion: The rapid abandonment of an old river channel and the formation of a new one.
Mid-channel Bar: An accumulation of sediment found within the main channel of a river, often leading to flow division.
Riparian Vegetation: The plant life that grows along the banks of rivers and streams.
