Reg movement monitoring and Barchans in West of Lot region (Pashoeyeh)
Abstract:   (1083 Views)
The most important characteristic of sand dunes, dynamics and their lateral movement, which some of them are crisis centers and Privacy-threatening centers of Residential, urban, rural, economic, military and arteries of communication. The case study which, village is located at the Pashoeyeh of Shahdad district and in the East of the city of Kerman in the desert on the west side Nayband fault, there is a rather dynamic rig and some single barchans. As a result of different period's floods, has been created crusts so that pebble and barchans are moving between them. In this study, using the crust and compare it with aerial photos of different years, the movement of reg and barchans measured and compared. Using aerial photographs (scale 1: 55,000, in 1334- a scale of 1: 20,000 in 1348, and the scale of 1: 40,000, 1374) and Google Earth satellite images, in 2005, the movement of rig and barchans, with crust factor, and also by checking the wind roses at different time periods studied and compared. The study concluded that the rig is shifting to the South and South East, and based on field studies movement in the second barchan 96, and first barchan 135 meters measured. The results of the study about time of crust and the barchans movement in compare with tig, have confirmed these findings. In addition, the results show that the crust caused by the floods in the area, except calculating of sand movement amount, you can also specify the time of flooding in the region. According to the annual movement of barchans in the area, the rainfall and flooding of area, is related to 1994.
Keywords: barchan, crust, Pashoeyeh, Reg, Loot desert, the wind indicator.
