River networks exert a primary control on the evolution of orogens through the advection of material away from their surfaces. However fundamental questions are emerging about how river networks evolve over time, in particular the degree to which river networks are subject themselves to 'deformation'. For example, is the evolution of river networks static or ever changing? Can river networks be simply advected statically across orogens along with rocks and topography or are they subject to strain imposed by the deforming orogen? Answers to these questions will increase our capability of using present topography to understand the past, e.g. by inverting landscape topography or by using river networks as markers of deformation. We therefore welcome contributions on any aspect of the kinematics and dynamics of river networks in deforming orogens ranging from field-based studies and data-based approaches to conceptual and numerical investigations.
