Title

IDENTIFICATION OF STORM SRONE AREAS OF DESERT PLAINS BY COMBINATION OF WIND ROZE, STORM ROZE AND SAND ROZE GRAGH RESULTS (CASE STUDY: BAFGH CITY)

Pages

  39-44

Abstract

 Wind erosion is one of the most important natural processes in semi arid, arid and hyper arid regions. This process occurs in conditions that wind has considerable speed and abundance in addition to existence of sensitive soil. Bafgh city is one of the arid regions of Central Iran has low rainfall and poor plant cover. Strong winds blowing on the surface of these non-coverage land causing soil erosion and other problems. Identify Storm prone areas could reduce its risks and losses. So identification and controlling of storm prone areas, the wind erosion threshold velocity should be determined in different FACIES foremost. In this study, the threshold velocity of each FACIES was measured by using of wind erosion meter (W.E. meter), and the iso-threshold velocity map of wind erosion was provided. For analyzing critical wind speed and aspect, the anemometers data of Bafgh synoptic station during 14 years statistical period was used. Grueling winds condition of this region was studied by Wind Rose (WRPLOT view 5.2.1) and Sand Rose (Sand Rosegragh 3.0) software. Results showed grueling winds blow from Northeast in 39 percent of the study area are fine grain plain FACIES with parabolic surfaces and Nebka, sand dunes FACIES gardens and residential areas, and medium grain plain with medium reg and oued. The threshold velocity in these areas was 7 to 16 meters per second.
