Estimation of land subsidence hazard using interferometry of satellite radar images Available to Purchase

Increased exploitation of underground resources is one of the main reasons of subsidence occurrence. Subsidence causes infrastructure damage and ultimately leads to increased risk to society and the economy. In some areas of Iran recently, buildings, runways, bridges, tunnels, streets, railways and roads have been severely damaged. In this study, the amount of land subsidence was analysed in the western region of Kerman City using interferometry of radar images of Sentinel-1 satellite data from 2014 to 2020 in the Sentinel Application Platform software. The results show that the subsidence rate in the area changed between 3.3 and 13.2 cm, confirming a significant increase. Field studies indicate that increased exploitation of groundwater resources, compaction due to ground drainage and imposition of heavy loads can all cause subsidence, which leads huge damage to the infrastructure.
