Analysis of sedimentary texture and effects of vegetation in the Nebkha dunes of Shahdad, eastern Kerman: Application in the formation mechanism

Sara Ebrahimi Meymand; Hamed Zand-Moghadam; Mohammad Khanehbad; Asadollah Mahboubi Mahboubi; Gholamreza Hosseinyar

Volume 29, Issue 115 , June 2020, , Pages 27-38


  Nebkhas are one of the aeolian dunes that play an important role in wind erosion by stabilizing sediments around plants. Due to the depression of northern Shahdad plain (eastern Kerman), the sever wind impact, high rate of sediment supply and the presence of desert plants, nebkhas have expanded. In this ...  Read More
