Subsidence Detection in Mahyar Plain of Isfahan Using InSAR

In recent years, because of population growth and water shortages due to global warming, groundwater use in agriculture, industry and households has been growing. This is one of the main causes of subsidence occurred in Iran. To study this phenomenon, some approaches such as GPS and geodetic leveling can be used. But the study of this phenomenon becomes easier by using InSAR technique. Using this technique, the displacement in the region field without the need for large working, with high precision, and with less expenditure can be observed. In this report, in temporal and spatial changes subsidence in Mahyar of Isfahan is studied. About 30 years ago in the plains and rift-related subsidence has been observed that the deformation of serious damage to agricultural land, roads and constructional. .. is followed. For that, 15 images of InSAR of ENVISAT within the period 2006-2003 with short base (SBAS) method were used. This method is provided subsidence map. Base on result, there is an 8.6 cm of subsidence in Mahyar.
