In the Beijing plain, the long-term groundwater overexploitation, exploitation, and the utilization of superficial urban space have led to land subsidence. In this study, the spatial–temporal analysis of land subsidence in Beijing was assessed by using the small baseline subset (SBAS) interferometric synthetic aperture radar (InSAR) technique based on 47 TerraSAR-X SAR images from 2010 to 2015....

In this paper, two centrifugal model tests (case 1: raft foundation, case 2: 2x2 piled raft foundation) were conducted in order to evaluate the effect of ground subsidence on load sharing among piles and raft and settlement of raft and piled raft foundations. For each case, two conditions consisting of undrained (without groundwater pumping) and drained (with groundwater pumping) conditions wer...

It is known that several areas in Shanghai town are affected by strong subsidence and many studies are being carried on for monitoring its ground motion. Moreover, the city is growing more and more both in extension and height, and this fact can be connected to the subsidence phenomena. In this work, carried out within the ESA Dragon project, all the available data acquired by ESA satellites ER...

This paper presents a new time-series InSAR analysis approach, Coherent Point Target Analysis (CPTA), to accurately map surface subsidence. The approach focus on the selection and analysis of sparse coherent point targets which exhibit phase stability over a long period of time. By jointly exploiting temporal and spatial characteristics of the interferometric phases collected from coherent targ...

This paper presents the development and application of a conjunctive water management model for lowland catchments. The model incorporates a simulation model and a management model to simulate groundwater movement, ground consolidation and to search for the potential pumping amount of groundwater without violating physical and environmental constraints. The results reveal that groundwater level...

This study presents the spatial and temporal grounddeformation pattern of the Nisyros-Yali volcanic field after the period of the seismic crisis (1996-1998) based on the local GPS network remeasurement and the analysis of Interferometric data (2003-2010) applying the SqueeSAR technique. The GPS results indicated intense subsidence in the northern and central parts of Nisyros that caused the wes...

In recent years, Persistent Scatters (PS) Synthetic Aperture Radar Interferometry (InSAR) technology has been proved to be a powerful tool that can provide high resolution information on topology and ground displacement monitoring of up to millimetric accuracy. In this project, we studied the ground deformation of the area of interest (AOI) in Hong Kong urban area by means of PSInSAR technology...

Subsidence can be caused by a diverse set of human activities and natural processes, including mining of coal, withdrawal of ground water, petroleum, and melting of permafrost. More than 80 percent of the identified subsidence in the Nation results from underground water pumping. The increasing development of urban area and need of water resources threaten to exacerbate existing land subsidence...
