Measuring Spatiotemporal Features of Land Subsidence, Groundwater Drawdown, and Compressible Layer Thickness in Beijing Plain, China
Beijing is located on multiple alluvial-pluvial fans with thick Quaternary unconsolidated sediments. It has suffered serious groundwater drawdown and land subsidence due to groundwater exploitation. This study aimed to introduce geographical distribution measure methods into land subsidence research characterizing, geographically, land subsidence, groundwater drawdown, and compressible layer th...
متن کاملImaging Land Subsidence Induced by Groundwater Extraction in Beijing (China) Using Satellite Radar Interferometry
Beijing is one of the most water-stressed cities in the world. Due to over-exploitation of groundwater, the Beijing region has been suffering from land subsidence since 1935. In this study, the Small Baseline InSAR technique has been employed to process Envisat ASAR images acquired between 2003 and 2010 and TerraSAR-X stripmap images collected from 2010 to 2011 to investigate land subsidence in...
متن کاملLand subsidence induced by groundwater extraction: the case of Bologna
A comprehensive investigation of the subsidence induced in the area of Bologna (Italy) by groundwater extraction is presented. Initially, the geological pattern of the region is reviewed in order to identify the large scale subsoil features governing the water flow regime and the ground displacements. Several types of data, covering the different aspects of the problem are then combined into a ...
متن کاملCharacterization of regional land subsidence induced by groundwater withdrawals in Tehran, Iran
Generally, alluvial basins of arid and semiarid zones are the places with excessive groundwater withdrawal, and also they have a high potential for land subsidence. Excessive groundwater withdrawals have caused severe land subsidence in Tehran, Iran. At present, the maximum land subsidence rate is 36 cm/year, covering an area of nearly 530 km2. In the 2000s, as a result of economic and populati...
متن کاملPs-insar Measurement of Land Subsidence in Bangkok Metropolitan Area
It is well known that the metropolitan area of Bangkok, Thailand, has been subsiding during the past decades. This ground deformation has been monitored using leveling networks on annual basis since 1978. However, the employed technique is costly, time-consuming, and able to monitor only on a limited number of benchmarks. InSAR (Interferometric Synthetic Aperture Radar), which can provide sub-c...
