An important challenge in geomorphology is the reconciliation of the high fluvial incision rates observed in tectonically active mountain ranges with the long-term preservation of significant mountain-range relief in ancient, tectonically inactive orogenic belts. River bedrock erosion and sediment transport are widely recognized to be the principal controls on the lifespan of mountain ranges. But the factors controlling the rate of erosion and the reasons why they seem to vary significantly as… Expand
Mechanics of Sediment Transport and Bedrock Erosion in Steep Landscapes
Erosion is concentrated in steep landscapes such that, despite accounting for only a small fraction of Earth’s total surface area, these areas regulate the flux of sediment to downstream basins, andExpand
A mass-wasting dominated Quaternary mountain range, the Coastal Range in eastern Taiwan
Abstract Fluvial bedrock incision, which creates topographic relief and controls hillslope development, has been considered the key medium linking denudation and tectonic uplift of unglaciatedExpand
Controls on Fluvial Geomorphology in the Canadian Rocky Mountains
The Canadian Rocky Mountains record a dynamic history of erosion. Presently, bedrock rivers interact with the lithology and structural architecture of a large fold-and-thrust belt. Because the alpineExpand
Landslides, threshold slopes, and the survival of relict terrain in the wake of the Mendocino Triple Junction
Establishing landscape response to uplift is critical for interpreting sediment fluxes, hazard potential, and topographic evolution. We assess how landslides shape terrain in response to a wave ofExpand
Topographic stress control on bedrock landslide size
Landslides are a major natural hazard and act as a primary driver of erosion, chemical weathering and organic carbon transfer in mountain ranges. Evaluating the impact of landslides on Earth systemsExpand
Beyond the angle of repose: A review and synthesis of landslide processes in response to rapid uplift, Eel River, Northern California
Abstract In mountainous settings, increases in rock uplift are often followed by a commensurate uptick in denudation as rivers incise and steepen hillslopes, making them increasingly prone toExpand
Boulders as a lithologic control on river and landscape response to tectonic forcing at the Mendocino triple junction
Constraining Earth’s sediment mass balance over geologic time requires a quantitative understanding of how landscapes respond to transient tectonic perturbations. However, the mechanisms by whichExpand
Lithological controls on hillslope sediment supply: insights from landslide activity and grain size distributions
The volumes, rates and grain size distributions of sediment supplied from hillslopes represent the initial input of sediment delivered from upland areas and propagated through sediment routingExpand
Numerical investigations of subglacial hydrology as a direct and indirect driver of glacial erosion
Glaciers shape high altitude and latitude landscapes in numerous ways. Erosion associated with glacial processes can limit the average height of mountain ranges, while creating the greatest relief onExpand
Long-term patterns of hillslope erosion by earthquake-induced landslides shape mountain landscapes
TLDR
These results are the first demonstration that repeated large earthquakes can consistently focus erosion at high elevations, while interseismic periods appear less effective at modifying the highest parts of the topography. Expand

Abstract We review the role of landslides in current concepts of the topographic development of mountain ranges. We find that many studies in this field address basin- or orogen-scale competitionExpand

A strong coupling between hillslope and valley systems is often inferred for mountain landscapes dominated by bedrock landsliding. We reveal the nature of this link using data sets on landsliding andExpand

Deep landscape dissection by the Dadu and Yalong rivers on the eastern margin of the Tibetan plateau has produced high-relief, narrow river gorges and threshold hillslopes that frequently experienceExpand
Links between erosion, runoff variability and seismicity in the Taiwan orogen
TLDR
Erosion rates in the Taiwan mountains are estimated from modern river sediment loads, Holocene river incision and thermochronometry on a million-year scale and the pattern of erosion has changed over time in response to the migration of localized tectonic deformation. Expand

TLDR
Observations from a meteorological network across the Greater Himalaya, Nepal, along with estimates of erosion rates at geologic timescales from low-temperature thermochronometry are combined to predict spatial variations in precipitation and slopes and correlate with gradients in both erosion rates and crustal strain.
