Investigation of land Subsidence in Orzuiyeh Plain of Kerman Using Radar Differential Interference Method (DINSAR)

The Phenomenon of subsidence of the earth occures causing wide–raging problems and dangers. The occurrence of this phenomenon causes problems for farmers, the destruction of communication lines and infrastructures and some other issues. In this research from differential interference (DINSAR) and using ASAR sensor data from ۲۰۰۹ to ۲۰۱۰ and sensors sentinel ۱ in ۲۰۱۴ – ۲۰۱۵ in relation to the Kerman's Orzuiyeh plain, it is tried to depict the phenomenon of desertification in the picture of the Kerman valley. temporal and spatial Changes have been made in this plain. seascape software is used to process image The results of the series analysis the time has come to show that the region is continuously subsiding; the amount of subsidence per year ۲۰۰۸ to ۲۰۰۹ is ۱۵ centimeters, the most abandoned in the northwest and central plain and ۲۰۰۹ year by ۹, ۱۰۰ cm by ۲۰۱۰, which is still the high et amount of subsidence in the northwest and central plain and for the year ۲۰۱۴ to ۲۰۱۵ is ۸.۲ cm and the largest amount of this phenomenon is in the southeast part of the Orzuiyeh plain. looking at the pictures of the subsidence of these years can be concluded that Orzuiyeh's desertification is dynamic and has a trend from the north the west was southeast of the plain.
