Bridging point of a river
Braided river—A braided river is readily identified by its multitude of channels.
being meandering (see: Meander). Braided channels are known for
their shifting islands. Because the material is coarse, it does not stick together like clay and so cannot form a high bank to a channel.
As a result, braided channels cannot have steep sides, and to compensate for this, a braided river channel has to be much wider than a meandering river carrying the same amount of water. However, braided rivers can be easier to ford than meandering rivers, a feature appreciated in the past by pioneers such as those on America’s 19th- century Oregon Trail. The Platte River is a typically braided river and was described by one pioneer as “A mile wide and an inch deep.”
Branch
