In areas where groundwater overexploitation occurs, land subsidence triggered by aquifer compaction is observed, resulting in high socio-economic impacts for the affected communities. In this paper, we focus on the Konya region, one of the leading economic centers in the agricultural and industrial sectors in Turkey. We present a multi-source data approach aimed at investigating the complex and...
Land subsidence in the Bandung basin, West Java, Indonesia, is characterized based on differential interferometric synthetic aperture radar (DInSAR) and interferometric point target analysis (IPTA). We generated interferograms from 21 ascending SAR images over the period 1 January 2007 to 3 March 2011. The estimated subsidence history shows that subsidence continuously increased reaching a cumu...
Many provinces in China including Shanghai, Tianjin, Jiansu, Hubei, Hangzhou, Suzhou, Changzhou, Cangzhou, and Jianxing (Deng and Ju, 1994; Ding et al., 2005; Hu et al., 2004; Xue et al., 2005; Yang et al., 2005) are subsiding owing to rapid development and urbanization. The cause identified with these subsidence phenomena has been mainly due to excessive withdrawal of groundwater (Chai et al.,...
Contemporary applications of radar altimetry include sea-level rise, ocean circulation, marine gravity, and icesheet elevation change. Unlike InSAR and GNSS, which are widely used to map surface deformation, altimetry is neither reliant on highly temporally-correlated ground features nor as limited by the available spatial coverage, and can provide long-term temporal subsidence monitoring capab...
Chiayi County is located in the largest alluvial plain of Taiwan with extensive aquaculture and rice farming sustained by water extracted from groundwater wells. Chiayi is a typical aquaculture area affected by land subsidence, yet such lands worldwide combine to provide nearly 90% of global aquaculture products, greatly reducing oceanic overfishing problems. This study uses precision leveling,...
The centre of the Turku city by the river of Aurajoki in Finland has been built on clay and silt soil. The level of the ground water has been constantly lowering during the last few centuries due to the postglacial land uplift and extensive water usage leaving the old wooden pilework exposed to decaying. The decaying has led to the subsidence of some historical buildings in the old centre of Tu...
We present in this contribution the results of the first experiment to monitor land subsidence along JingJin High Speed Railway (JingJin HSR), which connects Beijing city and Tianjin city and is the first high speed railway in China, by using the Permanent Scatterer InSAR (PSI). Since the length of the railway is usually beyond the standard scenes coverage of the ongoing radar satellite, i.e. E...
In this research, a technique to estimate the volume change by using Differential Interferometric Synthetic Aperture Radar (DInSAR) is proposed to retrieve the volume change of long-term continuously land deformation (subsidence or uplift). This technique is employed to investigate subsidence of Bandung city, Indonesia to demonstrate the capability of this technique by assessing two Japanese L ...
The current global projections of future sea level rise are the basis for developing inundation hazard maps. However, contributions from spatially variable coastal subsidence have generally not been considered in these projections. We use synthetic aperture radar interferometric measurements and global navigation satellite system data to show subsidence rates of less than 2 mm/year along most o...
The development of agriculture and industry and the increase of population in countries with arid to semi-arid climates have led to more harvesting of groundwater resources and as a result land subsidence in different parts of the worlds. Decades of groundwater overexploitation in the Kashmar-Bardaskan plain in the north-east of Iran has resulted substantial land subsidence in this plain. The p...
