Tanana River Channels


Braided river systems such as the Tanana River have multiple interconnected channels, resembling the strands of a braid, with a very low stream gradient. With an annual suspended sediment load of about 37 million tons, the complex channel pattern of this river is the result of erosional processes that have been going on for centuries. This aerial perspective shows the wild nature of the river channels and their relationship with the vegetated and non-vegetated islands alike.
