Title

Investigation of evolution in Gavkhouni wetland muddy zones by using fractal model

Pages

  113-127

Abstract

 In recent years, Phenomena such as population growth, the expansion of large cities, the human activities and climate change, caused of a reduction in wetland’ s water, which causes temporary or permanent drying in some of them including Gavkhouni wetland. For investigation of the effects of drying on the Gavkhouni, Playa micro-forms situation was evaluated. By using fractal model perimeter-area, micro-landforms were evaluated in 2 consecutive years. The DAP values obtained, in 2013 showed a quantity of 1/27 to 1/40 and in 2014, values 1/27 to 1/44. For evaluating of the area’ s climate, monthly total precipitation and minimum and maximum monthly air temperature climate charts were drawn, related to the years 2013 and 2014-Using data from the Varzaneh meteorological station. The climate charts indicated a decrease in rainfall from 120. 6 in 2013 to 87. 8 mm in 2014, an increase in the monthly minimum temperature from 3. 23 in 2013 to 3. 52 ° C in 2014, and an increase in the maximum monthly temperature from 29. 93 in 2013 to 30. 47 ° C in 2014. The obtained values from the fractal model showed that micro-landforms tend to increasing of chaos with the over of time. This chaos might have occurred because of the drying it. The results show that with the continuation of the Gavkhouni current trend, the desertification may be intensified and the increase of sedimentation of salt minerals on sedimentary deposits, also the expansion of the salt zone causes the conversion of the wetland to the desert.
