In recent years more attention has been paid on the mechanical and thermo-mecanical aspects of mountain building offering a better understanding of the behaviour of the continental lithosphere in subduction settings. Today, the major role of surface processes is highlighted in numerous studies dealing with the evolution of orogens at different time scales. For example, the role of erosion on exhumation and deformation history of accretionary orogens is widely studied through experimental and geological methods. The Session will be focused on the impact of surface processes on the dynamics of coulomb type thrust wedges. Predictions derived from the critical taper theory, which links topography and tectonics in a convergent wedge, show that syntectonic erosion affects the critical state of the orogenic wedge and that the dynamics between tectonics, erosion and sedimentation contain important feedback mechanisms such that orogenic systems tend toward a steady state. In order to provide a timely comprehensive overview of processes governing the evolution of orogenic belts we invite contributions dealing with the interaction between tectonics and surface processes in convergent settings. Modern innovative and/or multidisciplinary approaches (analogue and numerical modelling, imagery, quantitative geomorphology, geodesy) are welcome as much as classical regional field studies that deal with spectacular case examples taken in fossil or active orogens (e.g. Taiwan, Southern Alps of New Zealand, Cascadia orogen, Himalayas, Alps...) and all studies exploring the role of individual parameters.
