Summary
The orientation or trend of dunes with respect to wind direction has long been a focus of dune research, especially for dunes that form in multidirectional wind regimes. The concepts of the gross bedform-normal transport (GBN) and the bed instability and fingering modes provide analytical solutions for understanding how dunes are oriented to sand-transporting winds and indicate the importance of sand supply for dune morphology in multidirectional wind regimes. They help to explain complex dune patterns and the existence of superimposed bedforms on megadunes.
