a r t i c l e i n f o Keywords: Subsidence Interferometric synthetic aperture radar SBAS time-series Indonesia We use interferometric synthetic aperture radar (InSAR) time-series analysis of ALOS L-band SAR data to resolve land subsidence in western Indonesia with high spatial and temporal resolution. The data reveal significant subsidence in nine areas, including six major cities, at rates up ...

Due to the rapid growth of economy in China, the amount of water usage has increased dramatically in many major cities. The over exploitation of underground water in the north region of China causes severe urban subsidence over last 3 decades. The conventional surveying methods have been used to monitor the subsidence. It is, however, very challenging to identify the coverage of the subsidence ...

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...

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...

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...

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...

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...
