Lithology-controlled subsidence and seasonal aquifer response in the Bandung basin, Indonesia, observed by synthetic aperture radar interferometry
نویسندگان
چکیده
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 cumulative 45 cm during this period, and the linear subsidence rate reached ∼12 cm/yr. This significant subsidence occurred in the industrial and densely populated residential regions of the Bandung basin where large amounts of groundwater are consumed. However, in several areas the subsidence patterns do not corre-

Study of subsidence of Abarkooh plain of Yazd using the Synthetic Aperture Radar Interferometry method
Abstract The population growth, the development of cities, industry, agriculture, and improper use of resources especially non-renewable resources have led human beings to face the danger of running out of resources. In some cases, in addition to the above, irreversible environmental and geological hazards have occurred due to the overdrawn of resources. Over extraction of groundwater resourc...
متن کاملSeasonal subsidence and rebound in Las Vegas Valley, Nevada, observed by synthetic aperture radar interferometry
Analyses of areal variations in the subsidence and rebound occurring over stressed aquifer systems, in conjunction with measurements of the hydraulic head fluctuations causing these displacements, can yield valuable information about the compressibility and storage properties of the aquifer system. Historically, stress-strain relationships have been derived from paired extensometer/piezometer i...
متن کاملApplication of Displacement Map Produced by Interferometric Synthetic Aperture Radar Technique in Height Datum Determination in the Subsidence Area
Damages due to subsidence such as destruction of watering system and agricultural fertile soil, wells increasing, damage to the roads, bridges and high ways and disordering in the water and gas supplying usually are irreparable and costly. As a huge amount bench marks of height network of Iran are placed in the subsidence area, changing their heights is a challenge for NCC. In this study, a new...
متن کاملDetection of aquifer system compaction and land subsidence using interferometric synthetic aperture radar, Antelope Valley, Mojave Desert, California
Interferometric synthetic aperture radar (InSAR) has great potential to detect and quantify land subsidence caused by aquifer system compaction. InSAR maps with high spatial detail and resolution of range displacement (610 mm in change of land surface elevation) were developed for a groundwater basin (;10 km) in Antelope Valley, California, using radar data collected from the ERS-1 satellite. T...
متن کاملPredicting land subsidence rate due to groundwater exploitation in the district 19 of Tehran using MODFLOW and InSAR
During recent years, groundwater exploitation and thereby decreasing hydraulic head in the compressible sedimentary aquifer which is placed in the district 19 of Tehran have been caused noticeable land subsidence. The land subsidence has been damaging the infrastructures which have been being built in the south of Tehran Basin, especially in the district 19 of Tehran. A finite-difference ground...
