A hierarchy of channel-form bounding surfaces generally partitions fluvial strata, each
reflecting river scouring processes at a different scale. Low-order (eg channel scours,
channel-belt boundaries, etc.) and high-order (ie valley-form sequence boundaries)
surfaces are discussed extensively in the literature. The intermediate-scale boundaries,
however, are largely overlooked. An understanding of the range of processes generating
these channel-form surfaces is pivotal for interpreting fluvial architecture and understanding …
