varying water- and sediment-discharge conditions

Key Points
- With no vegetation, deltas shift from few to many channels and global
to local avulsions with increasing water discharge.
- With high water or sediment discharge, vegetation tends to confine
flow into existing channels, restricting creation of new channels.
- With vegetation, increased sediment or water discharge results in a
more stable channel network through frequent channel reoccupation.
