“…This clearly demonstrates the process and cause of subsidence in the study area. Zhang et al [51] and Galloway et al [52] showed a similar relationship and joint effect of natural and anthropogenic conditions with subsidence. Moreover, the identification of high subsidence particularly in the peripheries of tubewell locations showed a good ability of Sentinel 1A data and the IPTA approach for land subsidence mapping in this part of the region.…”

Land subsidence, as one of the engineering geological problems in the world, is generally caused by compression of unconsolidated strata due to natural or anthropogenic activities. We employed interferometric point target analysis (IPTA) as a multi-temporal interferometric synthetic aperture radar (MT-InSAR) technique on ascending and descending Sentinel-1A the terrain observation with progressive scans SAR (TOPSAR) images acquired between January 2015 and December 2018 to analyze the spatio-temporal distribution and cause of subsidence in Abbottabad City of Pakistan. The line of sight (LOS) average deformation velocities along ascending and descending orbits were decomposed into vertical velocity fields and compared with geological data, ground water pumping schemes, and precipitation data. The decomposed and averaged vertical velocity results showed significant subsidence in most of the urban areas in the city. The most severe subsidence was observed close to old Karakorum highway, where the subsidence rate varied up to −6.5 cm/year. The subsidence bowl profiles along W–E and S–N transects showed a relationship with the locations of some water pumping stations. The monitored LOS time series histories along an ascending orbit showed a close correlation with the rainfall during the investigation period. Comparative analysis of this uneven prominent subsidence with geological and precipitation data reflected that the subsidence in the Abbottabad city was mainly related to anthropogenic activities, overexploitation of water, and consolidation of soil layer. The study represents the first ever evidence of land subsidence and its causes in the region that will support the local government as well as decision and policy makers for better planning to overcome problems of overflowing drains, sewage system, littered roads/streets, and sinking land in the city.

“…This combination is being used to overcome the limits associated with each technique and to provide improved mapping, monitoring, and insights into the controlling geologic, hydrologic, and anthropogenic factors (Teatini et al 2005). An integrated ground-based monitoring approach in Houston, Texas that includes 13 borehole extensometers and regional groundwater level monitoring is being used by the Harris-Galveston Coastal Subsidence District to manage and mitigate land subsidence (Coplin and Galloway 1999;Galloway et al 2003;Zilkoski et al 2003). InSAR has been an important, recent addition to the integrated monitoring approach in Houston (Stork and Sneed 2002;Buckley et al 2003) and the future application of PSI in Houston and other subsidenceaffected coastal areas-e.g.…”

“…The consequences may include degraded water quality, reduced surface-water flows and storage, damages to wetland, riparian and aquatic ecosystems, increased production costs, and land subsidence, often with accompanying ground-surface fissuring and faulting. In some coastal regions subject to flooding such as Houston, Texas and Santa Clara Valley, California land subsidence is one of the principal constraints on the use of groundwater resources and, consequently, a major concern for groundwater management (Wilson and Gorelick 1996;Coplin and Galloway 1999;Galloway et al 2003;Ingebritsen and Jones 1999). Satellite-borne SAR interferometry, particularly InSAR, enhances our capabilities to map, monitor, analyze, simulate, and manage aquifersystem compaction and land subsidence at regional and local scales.…”

The application of satellite differential synthetic aperture radar (SAR) interferometry, principally coherent (InSAR) and to a lesser extent, persistent-scatterer (PSI) techniques to hydrogeologic studies has improved capabilities to map, monitor, analyze, and simulate groundwater flow, aquifer-system compaction and land subsidence. A number of investigations over the previous decade show how the spatially detailed images of ground displacements measured with InSAR have advanced hydrogeologic understanding, especially when a time series of images is used in conjunction with histories of changes in water levels and management practices. Important advances include: (1) identifying structural or lithostratigraphic boundaries (e.g. faults or transitional facies) of groundwater flow and deformation; (2) defining the material and hydraulic heterogeneity of deforming aquifer-systems; (3) estimating system properties (e.g. storage coefficients and hydraulic conductivities); and (4) constraining numerical models of groundwater flow, aquifer-system compaction, and land subsidence. As a component of an integrated approach to hydrogeologic monitoring and characterization of unconsolidated alluvial groundwater basins differential SAR interferometry contributes unique information that can facilitate improved management of groundwater resources.

“…Groundwater was developed by the 1940s in Houston to meet a growing public and industrial water demand, especially near Galveston Bay and the Houston Ship Channel. By 1979, subsidence had locally exceeded 3 m, and more than 8000 km 2 of land had subsided at least 0.3 m. Figure 3 shows the subsidence patterns from 1906 to 1995, which indicate that the recent subsidence has shifted spatially from near the bay to inland areas north and west of Houston (Coplin and Galloway, 1999;Stork and Sneed, 2002;Galloway et al, 2003).…”

This paper reviews the mechanism of land subsidence, its occurrence and history, impacts, and efforts by society to control this phenomenon in the United States. It also speculates about potential long-term consequences and the legacy of subsidence for future generations.
