The interactions among climate, erosion, and tectonics have long been of interest to geologists, but have not yet been united into a single theoretical framework. In this study, representations of orographic precipitation and fluvial erosion are combined with the concept of a critical wedge orogen. The idealized framework captures the basic system dynamics. It also allows for a formal analysis of the precipitation and tectonic interactions in terms of feedback factors and gains, and so permits… Expand
Climate and tectonic controls on glaciated critical-taper orogens
Abstract In this work we present the results of a new analytical model that examines the coupling between glacial erosion and orogen development. Surface processes are assumed to be glaciallyExpand
Critical form and feedbacks in mountain‐belt dynamics: Role of rheology as a tectonic governor
[1] The rheology that governs deformation within a convergent orogen also controls its topographic form, or in other words, the covaration of its height (or thickness) and its width. Under conditionsExpand
Rapid exhumation in the Western Alps driven by slab detachment and glacial erosion
Identifying topographic and erosion rate response to tectonic and climatic forcing remains challenging. This is in part because of the difficulty in isolating the respective roles of climate andExpand
The effects of lithology and base level on topography in the northern alpine foreland
Abstract The evolution of topography is driven by climate and tectonics, and strongly influenced by substrate properties and different base levels. The contributions of these factors may vary inExpand
Climate‐tectonic coupling: Variations in the mean, variations about the mean, and variations in mode
Interactions among tectonics, volcanism, and surface weathering are critical to the long-term climatic state of a terrestrial planet. Volcanism cycles greenhouse gasses into the atmosphere. TectonicsExpand
Tectonics, climate, and mountain topography

Dynamics of long term fluvial response in postglacial catchments of the Ladakh Batholith, Northwest Indian Himalaya
Upland rivers control the large-scale topographic form of mountain belts, allow coupling of climate and tectonics at the earth’s surface and are responsible for large scale redistribution of sedimentExpand
Three‐dimensional numerical simulations of crustal systems undergoing orogeny and subjected to surface processes
As several modeling studies indicate, the structural expression and dynamic behavior of orogenic mountain belts are dictated not only by their rheological properties or by far-field tectonic motion,Expand

Prior studies evaluated the interplay between climate and orography by investigating the sensitivity of relief to precipitation using the stream power erosion law (SPEL) for specified erosion rates.Expand
Fluvial and tectonic geomorphology of orogenic plateaux
Geomorphology is an expression of processes acting upon an area. The links between driving processes and the resulting geomorphology are far from being fully understood. This thesis investigatesExpand

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 theExpand
