Abstract

Bagnold's model for the formation of seif dunes from barchans, supported by Lancaster (1980) is reviewed. A new model was developed, based on field work done in the northern Sinai desert, that does not differentiate between the effects of strong and gentle winds. The horn that is elongated according to the new model is the one opposite the direction of the side winds. Only this horn is located so that the two main wind directions encounter it from both sides and develop movement of sand along the horn resulting in elongation.-Author
