TL;DR: The authors used detrital cosmogenic 10 Be from 50 basins, ranging in size from 1 to 150 km 2, to measure millennial erosion rates across the San Gabriel Mountains in southern California, where a strong E-W gradient in relief compared to weak variation in precipitation and lithology allow them to isolate the relationship between topographic form and erosion rate.

TL;DR: In this paper, the relationship between steepness and erosion rate in the San Gabriel Mountains can be explained using a simple stochastic-threshold incision model where the distribution of large floods follows an inverse power law.

TL;DR: The depth of the Earth's soil cover is controlled by the competing processes of soil production and erosion, and estimates of the rates of these processes over rugged topography suggest that soil-production rates will increase over surfaces that are subject to rapid erosion as discussed by the authors.

TL;DR: In this paper, the authors show that the width of bedrock channels is similar to alluvial rivers with the same discharge and follows the same scaling with drainage area, suggesting similar controls on channel width despite the difference in substrate strength.

TL;DR: In this article, a non-dimensional divide migration number, NDm, is defined as the ratio of the timescale of channel profile response to a change in drainage area (TdA) to the timescales of divide migration (TDm).
