The dynamic system of tectonics and erosion contains important feedback mechanisms such that orogenic systems tend toward a steady state. This concept is often invoked, but the nature of the steady state is commonly not specified. We identify four types of steady state that characterize the orogenic system and illustrate these cases by using numerical-model results and natural examples. These types are (1) flux steady state, (2) topographic steady state, (3) thermal steady state, and (4…

Steady state, continuity, and the erosion of layered rocks

Considerations of landscape steady state have substantially informed our understanding of the relationships between landscapes, tectonics, climate, and lithology. Topographic steady state, where

Characteristics of steady state fluvial topography above fault‐bend folds

[1] In steady state convergent orogens, erosion balances lateral as well as vertical bedrock motions. For simple geometrical reasons, the difference between the total steady state erosion flux and

Stream-power incision model in non-steady-state mountain ranges: An empirical approach

Stream-power incision model has always been applied to detecting the steady-state situation of ranges. Oblique arc-continent collision occurring during the period of Penglai Orogeny caused the Taiwan

Scale-dependent erosional patterns in steady-state and transient-state landscapes

TLDR
Scale-dependent erosional patterns, as observed in this study, suggest benchmarks in evaluating numerical models and interpreting the variability of sampled erOSional rates in field landscapes.

Fluvial response to horizontal shortening and glaciations : A study in the Southern Alps of New Zealand

[1] It has been postulated that a steady state between erosional and tectonic processes may develop in continental collision. However, it is not clear whether steady state conditions can be reached

Steady state, erosional continuity, and the topography of landscapes developed in layered rocks

Abstract. The concept of topographic steady state has substantially informed our understanding of the relationships between landscapes, tectonics, climate, and lithology. In topographic steady state,

Uplift, Shortening, and Steady State Topography in Active Mountain Belts

We present a tectonic, surface process model used to investigate the role of horizontal shortening in convergent orogens and the effects on steady-state topography. The tectonic model consists of a

FLUVIAL LANDSCAPE RESPONSE TIME: HOW PLAUSIBLE IS STEADY-STATE DENUDATION?

Whether or not steady-state topography and denudation are probable states depends on the timescale of system response to tectonic and climatic perturba- tions relative to the frequency of those

Orogeny and orography: The effects of erosion on the structure of mountain belts

A numerical model of the coupled processes of tectonic deformation and surface erosion in convergent orogens is developed to investigate the nature of the interaction between these processes. Crustal

Landsliding and the evolution of normal‐fault‐bounded mountains

Much of the tectonic and climatic history in high-relief regions, such as the mountains of the western U.S. Basin and Range province, is contained in the morphology of hillslopes, drainage networks,

Equilibrium and time scales in geomorphology: Application to sand-bed alluvial streams

Equilibrium is defined as a single-valued, temporally invariant functional relationship between the values of an output variable and the values of the input variable(s) in a geomorphic system.

Large‐scale geomorphology: Classical concepts reconciled and integrated with contemporary ideas via a surface processes model

Linear systems analysis is used to investigate the response of a surface processes model (SPM) to tectonic forcing. The SPM calculates subcontinental scale denudational landscape evolution on

SUMMARY We present here the results of numerical models of the Southern Alps in which the thermal and dynamical developments of the orogen are fully coupled to one another. This interlinkage allows
