It is important to control the aeorian sand transport for preventing the damage of road and agricultrual land in the inland desert of the United Arab Emirates.
This paper aims at clarifing the features of drifting sand and the transformation of sand dune in order to find out the procedure of control.
The results obtained are as follows.
1) Although the sand grains on the dune crest and in the surface layer of sandy bare land have median size of 0. 20 mm, size distribution characteristics differed from each other. Because the latter is more uniform, it should be consisted by the sand drift from the dune.
2) One half and more of annual sand drift could be related to the sand-storms before rainfalls, whose opportunities are not so many, indeed. This should be a feature to be considered before making good efforts for sand control.
3) Regression analysis of sand drift collected and wind speed yielded the annual rate of 11. 11 and 0. 23 ton per unit width in meter for the dune crest and the sandy bare land, respectively.
4) The linear dunes in this resion would be transformed by dominant wind which is bidirectional and incident the crest line at acute angle.
