SIMULATING STUDY ON BARCHAN DUNE
《Chinese Geographical Science》1998年第2期73-80,共8页凌裕泉 吴正 刘绍中 李长治 
Barchan dune is one of the basic forms of eolian landform, it is usually moulded by highconcentration nonsaturated windsand flow. The formation process of barchan dune begins from “wavegrain duality” of windsand mov...
