Aeolian processes are active at a myriad of spatial and temporal scales. What links these together and how important is process-form feedback in shaping these environments. This session brings together research traversing the spectrum, 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 and associated bedforms in a range of environments, from coastal and semi-arid regions, to hyper arid deserts. Contributions that use novel instrumentation in field studies, remote sensing at the landscape scale or innovative numerical modelling methods, are encouraged, particularly those which attempt to elucidate feedback between surface properties and sediment transport.
