Title

The Role of Biological Windbreak in the Creation of Microclimate in Arid Areas of Dehloran, Ilam

Pages

  73-90

Abstract

 In this study, the ENVI-met Headquarter model was used to design a Biological Windbreak to control wind erosion, and wind tunnel was used to determine the Wind Erosion Threshold. In order to determine the Wind Erosion Threshold, soil samples were transferred to laboratory and exposed to dry air and transferred to wind tunnel. Then, the Wind Erosion Threshold velocity was measured by adjusting the wind flow velocity and using an anemometer. The data required for simulation with ENVI-met model include geographical location of the region, soil texture, average minimum and maximum temperature, average minimum and maximum relative humidity, average maximum wind speed and wind direction. Based on the simulation results, both designed windbreak for the Prosopis juliflora and Haloxylon aphyllum species can create microclimate in region. The wind speed decreased to the Wind Erosion Threshold in the Haloxylon aphyllum species windbreak and less than that in the Prosopis juliflora species windbreak. In general, in the Prosopis juliflora species windbreak temperature in the first and last row of the windbreak was 36. 12 and 34. 78˚ C, respectively. Besides, the lowest relative humidity in the first row was 28. 52% and reached to 33. 11% in the distance of 8h to 10h behind the first row. On the contrary, inside the Haloxylon aphyllum species windbreak, the temperature in the first row was 34. 67˚ C and in the last row was up to about 35. 21˚ C. Moreover, the highest relative humidity in the first and last row was 33. 28% and 31%, respectively. Therefore, the designed windbreak for the Prosopis juliflora species can protect the more distance behind the initial windbreak, reduce the wind speed to a longer extent from the initial windbreak, more effectively affect the microclimate of the area, and modify it. Thus, it is recommended as a suitable windbreak for the study area.
