Rock Strength Along A Fluvial Transect Of The Colorado Plateau - Quantifying A Fundamental Control On Geomorphology, Natalie Bursztyn, Joel Pederson

Bedrock strength is a key parameter that influences slope stability, landscape erosion, and fluvial incision. Yet, it is often ignored or indirectly constrained in studies of landscape evolution, as with the K erodibility parameter in stream-power models. Empirical datasets of rock strength suited to address geomorphic questions are rare, in part because of the difficulty in measuring those rocks at Earth's surface that are heterolithic, weak, or poorly exposed. Here we present a large dataset of measured bedrock strength organized by rock units exposed along the length of the trunk Green–Colorado River through the iconic Colorado Plateau of the western …

There has been renewed debate over the mechanisms and timing of both uplift and erosion in the Interior West. Yet, in order to understand the region’s long-term landscape evolution and patterns of topography a third factor of bedrock properties must be considered. We are completing a large dataset of bedrock strength and exploring it in the context of reach-scale topographic metrics for the upper Colorado River system. Included are rock-strength measures such as laboratory tensile strength, Schmidt-hammer compressive strength, approximate shale proportion, and Selby rock mass strength classification. To estimate the strength of units too incompetent to test directly, such …
