Abstract Several million hectares of Indonesian peatlands have been converted to plantations, with oil palm being the most important plantation crop. This has contributed economic development Indonesia. At same time, it poses environmental challenges. An as yet insufficiently understood concern is that drainage required for cultivation causes soil subsidence. Subsidence progressively increases ...

Spaceborne SAR Differential interferometry (DInSAR) has been used to monitor some geological disasters such as ground subsidence. This paper applies two Permanent Scatterer InSAR(PS-InSAR) techniques to measure long-term and short-term subsidence in urban area of Shanghai urban. A great number of archieved ERS data are utilized to measure long-term subsidence during 1993-2000 year. A small set ...

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 ...

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...

The seepage and slope stability are very important and necessary in the dam dirt are, therefore, in this context, numerous applications to predict and calculate the rate of leakage has been prepared that than the experimental time and cost savings for the analysis of liquids before construction of earth dams need. In this study, safety factors for slope stability software Kaboodwal  plaxis two-...

In this paper, the decision-making information of subsidence area for twenty years is extracted, using Landsat multi-band and multitemporal remote sensing data, SPOT 5 texture features, DEM elevation, the methods of data fusion and principal component analysis and GIS technology, thereby the spatial and temporal distribution of change of subsidence area in mining is acquired from years 1987 to ...

abstract rice can be cultivated in various soils but soil with heavy texture and low permeability is more appropriate for its growth than other types of soil texture. it’s assumed that existence of zeolite in soil can be effective for moisture retention and avoiding of occurrence of crack in soil. in order to investigation of the effect of zeolite on moisture status and hydraulic properties of ...

We present a model of ground subsidence due to soil consolidation within coastal reclaimed land constructed in early 2001, Busan, South Korea. estimate 42 cm maximum during the period interferometric synthetic aperture radar observations, and 1 m or more subsidence, since end construction phase reclamation project. A hyperbolic was used relate three independent time series nonlinear behavior su...

Beijing is located on multiple alluvial-pluvial fans with thick Quaternary unconsolidated sediments. It has suffered serious groundwater drawdown and land subsidence due to groundwater exploitation. This study aimed to introduce geographical distribution measure methods into land subsidence research characterizing, geographically, land subsidence, groundwater drawdown, and compressible layer th...
