"Colluvial channels are small headwater streams at the tips of a channel network that flow over a colluvial valley fill and exhibit weak or ephemeral fluvial transport."

Channel Morphology of Colluvial Hollows
(Information compiled by A. Bryden)
Shallow concentrations of surface water flow are largely insufficient to transport the available sediment load in colluvial hollows. Hillslope processes such as debris flows and rock slides dominate sediment transport and distribution. Although fluvial scour and deposition may occur on a local scale, transport capacity is the limiting factor.
