The role of talus size distribution & the frequency of transport in wide and narrow valleys on bedrock valley widening: Buffalo National River, Arkansas
Bedrock river valleys are a valuable resource from which we learn about historic climactic changes, shifts in discharge and sediment inputs, movement of the river channel, and bedrock valley widening processes. Bedrock river valleys are often found in two end-member states: narrow, canyon-like …

Valley Widening and the Composite Nature of Valley Margin Sequence Boundaries: Evidence from the Neilson Wash Compound Valley Fill, Cretaceous Ferron Sandstone, Utah
Incised valleys are at the center of a debate about whether sequence boundaries are chronostratigraphically significant. Current research has suggested that the sequence boundary that makes up the floor and walls of an incised valley is constantly being modified throughout the entire relative …
