  author={Rong Yang and Sean D. Willett and Liran Goren},
Landscapes on Earth retain a record of the tectonic, environmental and climatic history under which they formed. Landscapes tend towards an equilibrium in which rivers attain a stable grade that balances the tectonic production of elevation and with hillslopes that attain a gradient steep enough to transport material to river channels. Equilibrium low-relief surfaces are typically found at low elevations, graded to sea level. However, there are many examples of high-elevation, low-relief… 

In situ development of high‐elevation, low‐relief landscapes via duplex deformation in the Eastern Himalayan hinterland, Bhutan

Prior studies have proposed tectonic and climatic mechanisms to explain surface uplift throughout the Bhutan Himalaya. While the resulting enigmatic, low‐relief landscapes, elevated above deeply

Geomorphology and topography of relict surfaces: the influence of inherited crustal structure in the northern Scandinavian Mountains

Low-relief surfaces in northern Norway are mapped and analysed to explore (1) whether surfaces were once continuous and possibly correlative, recording an ancient, relict landscape, (2) whether the

Topographic disequilibrium, landscape dynamics and active tectonics: an example from the Bhutan Himalaya

Abstract. The quantification of active tectonics from geomorphological and morphometric approaches commonly implies that erosion and tectonics have reached a certain balance. Such equilibrium

Distributed landscape response to localized uplift and the fragility of steady states

How Continuous Are the “Relict” Landscapes of Southeastern Tibet?

Pervasive low-relief, high-elevation surfaces separated by incised canyons are common across the Southeastern margin of the Tibetan Plateau and have been used to define the nature of crustal

Landscape response to progressive tectonic and climatic forcing in NW Borneo: Implications for geological and geomorphic controls on flood hazard

This study suggests that divide migration leads to lowered erosion rates, channel narrowing, and sediment accretion in intermontane basins on the leeward-side ultimately resulting in enhanced flooding.

Preservation or piracy: Diagnosing low-relief, high-elevation surface formation mechanisms

Absent clear lithologic control, the presence of elevated, low-relief topography in upland landscapes has traditionally been interpreted as a signature of relative surface uplift and incision of a

Formation Mechanism for Upland Low-Relief Surface Landscapes in the Three Gorges Region, China

It was concluded that the low-relief surfaces in the Three Gorges area did not share a common uplift history, and neither were they peneplain relicts, but rather that the effect of “area-loss feedback” caused by river capture has promoted the formation of upland low- Relief surface landscapes.

Topographic Relief Response to Fluvial Incision in the Central Tibetan Plateau: Evidence From Cosmogenic 10Be

Fluvial incision, regarded as one of the fundamental geomorphic processes, drives the evolution of mountainous landscapes. The transitional landscape from low‐relief to high‐relief in the central

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 of



Use of a regional, relict landscape to measure vertical deformation of the eastern Tibetan Plateau

[1] Field work and topography analysis show that remnant, local areas of a low-relief landscape or erosion surfaces are geographically continuous across the southeastern Tibetan Plateau margin. We

Dynamics of the stream‐power river incision model: Implications for height limits of mountain ranges, landscape response timescales, and research needs

The longitudinal profiles of bedrock channels are a major component of the relief structure of mountainous drainage basins and therefore limit the elevation of peaks and ridges. Further, bedrock

Dynamic Reorganization of River Basins

This work analyzed maps of a proxy for river elevation and horizontal movement of river drainage divides across three large river systems in China, Taiwan, and the United States, finding the Loess Plateau is close to geometric equilibrium, with χ exhibiting nearly equal values across water divides.

Beyond threshold hillslopes: Channel adjustment to base-level fall in tectonically active mountain ranges

Numerous empirical and model-based studies argue that, in general, hillslopes and river channels increase their gradients to accommodate high rates of base-level fall. To date, however, few data sets

Inland propagation of erosional escarpments and River profile evolution across the Southeast Australian passive continental margin

Denudation at passive continental margins occurs over time as erosional escarpments propagate inland, cutting through regions of elevated topography flanking ocean basins. Understanding the actual

Orographic barriers, high‐resolution TRMM rainfall, and relief variations along the eastern Andes

Quantifying the degree to which tectonic and erosive processes shape landscapes is key to understanding the evolution of tectonically active mountain belts. Here we explore the interplay of these two

Geomorphic constraints on surface uplift, exhumation, and plateau growth in the Red River region, Yunnan Province, China

Field observations, digital elevation model (DEM) data, and longitudinal profi le analysis reveal a perched low-relief upland landscape in the Red River region, Yunnan Province, China, which

Quantifying landscape differences across the Tibetan plateau: Implications for topographic relief evolution

[1] We quantify the bulk topographic characteristics of the Tibet-Qinghai plateau with specific focus on three representative regions: northern, central, and southeastern Tibet. Quantitative

Surface uplift, tectonics, and erosion of eastern Tibet from large‐scale drainage patterns

A new regional compilation of the drainage history in southeastern Tibet suggests that the modern rivers draining the plateau margin were once tributaries to a single, southward flowing system which
