Abstract:
Groundwater withdrawal is one of the most important causes of land subsidence all over the world that has caused extremely expensive damages to buildings, walls, roads, railroads, pipelines and casings of the water wells. Rafsanjan Plain has had the most subsidence in Iran. One of the necessary steps to perform a proper analysis for land subsidence is to obtain accurate measurements of actual land subsidence at certain intervals. In this paper, first the latest situation of land subsidence in Rafsanjan plain is described. Secondly the geological, hydrogeological conditions as well as groundwater utilization are explained. Finally the results of two successive measurements carried out recently as the first attempt in Iran to monitor land subsidence by using Global Positioning System (GPS) and modem remote sensing technique are presented
