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 deformation is calculated by a two-dimensional finite element model of deformation in response to subduction and accretion of continental crust. Erosion operates on the uplifted surface of this model through fluvial incision which is taken to be proportional to stream power. The relative importance… 

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

Numerical modelling of erosion processes in the Himalayas of Nepal: effects of spatial variations of rock strength and precipitation

Abstract The interplay between tectonics and erosion has a predominant control on the evolution of the morphology of mountain belts. Here we investigate the modalities of deformation in Central Nepal

Response of a steady-state critical wedge orogen to changes in climate and tectonic forcing

The theories of critical orogenic wedges and fluvial erosion are combined to explore the interactions between tectonics, erosion, and climate. A model framework is developed which allows the

Erosion and exhumation in accretionary orogens: Experimental and geological approaches

This study examines the role of erosion on exhumation and deformation history of accretionary orogens through experimental and geological methods. Fault propagation, kinematics, and exhumation rates

Numerical modeling of mountain building: Interplay between erosion law and crustal rheology

Coupling between erosion and tectonics is thought to play a determinant role in orogenic evolution. Here, we investigate the interplay in this coupling between the assumed erosion law and the crustal

Erosional control on the dynamics of low-convergence rate continental plateau margins

S U M M A R Y Over the last decade, thermomechanical models have revealed the control of both tectonics and erosion on the morphology of continental plateaus margins. However, unravelling the



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,

The evolution of deformation and topography of high elevated plateaus: 1. Model, numerical analysis, and general results

A temperature dependent viscoplastic flow model of continental lithosphere is used to investigate the evolution of deformation and topography of high elevated plateaus. Such plateaus are products of

Mechanical model for the tectonics of doubly vergent compressional orogens

A mechanical model of crustal shortening and deformation driven by the relative convergence of rigid, underlying mantle plates explains many features of convergent orogens. Results based on numerical

Mechanical model for subduction-collision tectonics of Alpine-type compressional orogens

Alpine-type orogens are characterized by three distinct convergent tectonic phases: subduction with deformation that has primarily single vergence, a transition from subduction to collision, and

Erosional dynamics, flexural isostasy, and long-lived escarpments: A numerical modeling study

Erosional escarpments are common features of high-elevation rifted continents. Fission track data suggest that these escarpments form by base level lowering and/or marginal uplift during rifting,

A geodynamic framework for interpreting crustal-scale seismic-reflectivity patterns in compressional orogens

SUMMARY 2-D, plane-strain finite-element models are used to calculate crustal deformation patterns within model compressional orogens and the results are compared with natural examples. The

Factors controlling the Alpine evolution of the central Pyrenees inferred from a comparison of observations and geodynamical models

Geodynamical numerical modeling has been combined with crustal structural restoration of the central Pyrenees in order to gain insight into fundamental processes that control the evolution of

Oblique convergence of the crust driven by basal forcing: implications for length-scales of deformation and strain partitioning in orogens

SUMMARY We investigate the effects of oblique convergence on crustal thickening by modelling the crust as a thin viscous sheet. Crustal deformation is driven by basal velocity boundary conditions

The continental collision zone, South Island, New Zealand: Comparison of geodynamical models and observations

The South Island zone of oblique continent-continent convergence occurs along a 400 km-long section of the modern Australia-Pacific plate boundary zone, across which about 50 km of shortening has
