Using hilltop curvature to derive the spatial distribution of erosion rates.
Erosion rates dictate the morphology of landscapes, and therefore quantifying them is a critical part of many geomorphic studies. Methods to directly measure erosion rates are expensive and time consuming, whereas topographic analysis facilitates prediction of erosion rates rapidly and over large spatial extents. If hillslope sediment flux is nonlinearly...Hurst, Martin D. ; Mudd, Simon M. ; Walcott, Rachel ; Attal, Mikael ; Yoo, Kyungsoo

Influence of lithology on hillslope morphology and response to tectonic forcing in the Sierra Nevada of California
[1] Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology may influence the efficacy of soil production and sediment transport on hillslopes. We performed quantitative analysis of LiDAR digital...Hurst, Hurst, Martin D ; Mudd, Simon M. ; Yoo, Kyungsoo ; Attal, Mikael ; Walcott, Rachel
