摘要
The migration of submarine, coastal and desert dunes is influenced by their morphological parameters. Analysis of the wave height and length of some representative large-scaled dunes indicates that these parameters are highly different among the submarine, coastal and desert dunes, with the height being the smallest for the submarine dunes and the largest for the desert dunes for the same range of lengths. There tends to be deviations of the height-length data points from statistical H-L curves, numerical experiments demonstrate that such deviations may be associated with the bedload transport rate.
