The underground water extraction induced subsidence has the characteristics of slow rate, less predictable location and coverage. Over a long time period, the cumulated subsidence can be up to a few metres. This paper demonstrates the feasibility and capability of using conventional two-pass differential interferometric synthetic aperture radar (DInSAR) for monitoring the underground water extr...

Shanghai maglev is a very fast traffic tool, so it is very strict with the stability of the roadbed. However, the ground subsidence is a problem in Shanhai because of the poor geological condition and some human-induced factors. So it is necessary to monitor ground subsidence in the area along the Shanghai maglev precisely and frequently. Traditionally, precise levelling method is used to surve...

In this work, ground deformation of the Shanghai coastal area is inferred by using the multiple-satellite Differential Synthetic Aperture Radar interferometry (DInSAR) approach, also known as the minimum acceleration (MinA) combination algorithm. The MinA technique allows discrimination and time-evolution monitoring of the inherent two-dimensional components (i.e., with respect to east-west and...

Subsidence rate in a reclaimed coastal land of Noksan industrial complex, Korea, was measured by C-band SAR differential interferometry (DInSAR). Surface conditions of the reclaimed land are very rough without vegetation with respect to C-band, which makes strong radar returns. However, artificially loaded top soil is subject to change within a short period so that it is difficult to obtain coh...

Satellite Synthetic Aperture Radar Interferometry (InSAR) techniques and, specifically, Advanced Differential InSAR techniques (A-DInSAR) are becoming, in last years, a powerful tool for the investigation of ground and structure deformations, also thanks to new space missions with last generation sensors able to provide high spatial resolution (about 3x3 m), high displacement accuracy and high ...

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...

Recent improvement to Advanced Differential Interferometric SAR (A-DInSAR) time series quality enhances the knowledge of various geohazards. Ground motion studies need an appropriate methodology to exploit the great potential contained in the A-DInSAR time series. Here, we propose a methodology to analyze multi-sensors and multi-temporal A-DInSAR data for the geological interpretation of areas ...

Coal mining activities all over the world often introduce serious environmental impact to the local regions, such as the occurrence of land subsidence. Conventional subsidence monitoring is done by precision leveling and GPS surveying. However, recent studies show that differential interferometric synthetic aperture radar (DInSAR) is capable of monitoring land subsidence at sub-cm accuracy. In ...
