Title

Estimation of the Frequency of Speed and Direction of the Erosive Winds and Dust storms in the Yazd Province, by Using Windrose, Stormrose and Sandrose

Pages

  96-106

Abstract

Wind erosion and generation of Dust is one of the most important problems in the Yazd province. To control this phenomenon and overcome the damages a lot of investment has been done for the implementation of many successful and unsuccessful projects across this province. Analysis of Erosive winds and estimation of the Resultant Drift Direction (RDD) of sand flow is the fundamental study by which can lead to a more successful implementation of projects, to control Wind erosion. In this study, by taking advantages of Wind-rose, Storm-rose and Sand-rose has been analyzed wind speed, wind direction and calculation of wind drift potential (DP) to represent a landscape of Wind erosion in the Yazd province and with the results of these analysis, the Resultant Drift Direction (RDD) of sand flow and Dust be estimated. The results showed that most of the Erosive winds in the Yazd province occur in the spring and summer and the lowest erosion occurs in autumn. The results as well revealed that the average percentage of Erosive winds which are capable of producing Dust are between 6. 4%, in Yazd city, and 23. 6%, in Herat city, and on average, in 44 days there is the possibility of Dust in the Yazd province. Therefore, although the prevalence of Erosive winds with speed more than 6 meter per second generally does not exceed 14% but, it has the most important role in the occurrence of the Wind erosion and Dust generation in the Yazd province and the mobility of a large amount of Dust is generally from the southwest and west to the north east and east.
