The Cosmolian program for simulating aeolian dynamics and its application to central Australia

Abstract The wide spatial coverage of sand dunes in continental interiors makes the understanding their activity and accumulation history valuable for palaeoenvironmental reconstructions interpretation landscape evolution. Nevertheless, study aeolian development at million‐year timescale is hampered by complex interaction factors determining dune migration inherently self‐destructive nature chronostratigraphy, thus limiting applicability traditional dating methods. This presents a standalone program that simulates transport based on luminescence‐derived chronologies coupled with numerical modelling cosmogenic nuclides. integrative approach to landforms reveals phases emergence into landscape, provides data‐based scheme facilitates morphodynamical processes over multiple timescales up several millions years. application reanalysing previously reported data from Australian Simpson Desert pulses dispersion central Australia 3.8–3.4, 2.9–2.5 1.5–1 Ma, corresponding pronounced changes climatic conditions deformation events. synchronicity results established environmental framework would promote production distribution exemplifies process‐based constructing timeframe key evolution events arid environments studying deposits. dependence parameters used determine settings transportation patterns additionally powerful tool further investigate triggers mechanisms processes.
