Aeolian processes operate at a myriad of spatial and temporal scales both on Earth and other planetary bodies. Process and form are linked by feedback mechanisms that drive the evolution of forms and at the larger scale the landscape itself. This session brings together research traversing the spectrum of scale, from long term landscape dating and evolution modelling to small-scale process studies. It will be of interest to researchers that study wind-blown sediment (both sand and dust sized particles) and associated bedforms in a range of environments, from coastal and semi-arid regions, to hyper arid deserts and other planets. Contributions that use novel instrumentation in field or laboratory studies, remote sensing at the landscape scale, innovative numerical modelling or theoretical approaches, are encouraged, particularly those which attempt to elucidate feedback between surface properties and sediment transport.
