Abstract

Relationships between riverbed morphology, concavity, rock type and rock uplift rate are examined to independently unravel the contribution of along-strike variations in lithology and rates of vertical deformation to the topographic relief of the Oregon coastal mountains. Lithologic control on river profile form is reflected by convexities and knickpoints in a number of longitudinal profiles and by general trends of concavity as a function of lithology. A key result from this analysis is that the rock resistance signal seen in hillslopes is a key control, and more important than rates of rock uplift in some cases, on the river profile and topographic relief
