Summary

The hypothesis of maximum friction factor states that the channel geometry evolves to a stable nonplanar shape when the friction factor reaches a local maximum. It is supported by published data on bed forms, channels with artificial roughness elements, meandering channels, and bed armoring. This hypothesis can be regarded as an extremal hypothesis. However, this hypothesis may not be invariably true.
