“…In comparison to the rate of groundwater-induced deformation in other well-known basins such as Las Vegas, USA (Bell et al, 2002), Mexico City, Mexico (Poland and Davis, 1969) and New Orleans, USA (Dixon et al, 2006), Iran currently hosts some of the fastest sinking valleys and plain aquifers in the world. Hence, unregulated groundwater extraction and the associated subsidence in the future may also threaten non-agricultural regions, resulting in costly damage to infrastructure due to changing ground levels.…”

“…Classical repeat-pass SAR interferometry is a suitable tool for detecting surface displacement and monitoring coherent areas [18][19][20][21]. Interferometric coherence is a pixel-based measure of the signal similarity between two SAR images and ranges from 0 (total decorrelation) to 1 (total correlation).…”

Remarkable Urban Uplift in Staufen im Breisgau, Germany: Observations from TerraSAR-X InSAR and Leveling from 2008 to 2011

et al. 2013

As geothermal energy is of increasing importance as a renewable energy source, there is a high demand for comprehensive studies to prevent failure during implementation, as is the case in Staufen im Breisgau, Germany. The drilling of seven wells for the geothermal heating of the city hall in 2007 is thought to have disturbed the existing hydro-geological system in the complex structured transition zone of the Upper Rhine Graben and the Schwarzwald massif. This event has led to uplift, related to the transformation of anhydrite to gypsum, which affects the infrastructure of the city centre via the generation of large cracks. This study focuses on the application of the InSAR Small Baseline Subset (SBAS) approach using 50 X-band radar images from the German TerraSAR-X satellite (TSX) to map the spatial and temporal patterns of the deformation field in detail. X-band InSAR time series analysis for the three-year time period from July 2008 through May 2011 indicates maximum velocities of ~12 cm/yr in the line of sight (LOS) direction, from the ground to the satellite, approximately 50 m northeast of the drilling field. In comparison with leveling data for the same time period, TSX data analysis better delineates the border of the deformation area, and it is able to map the amount of deformation associated with different parts of the city. Moreover, this comparison indicates contributions of horizontal motion, as is expected for uplift patterns.

“…The ground deformation is particularly unsettling when it occurs in large cities, where the recent intense urbanization implies growing water consumption with a significant pumping of the aquifers. This problem has been observed in many large cities such as Mexico City (Mays, 2009), Bangkok (Aobpaet et al, 2010), Shanghai (Lin et al, 2011), Venice (Brambati et al, 2003) and Las Vegas (Bell et al, 2002). The effects are significant when the urban area is situated on alluvial plains mainly composed of unconsolidated, compressible sedimentary formations.…”

Abstract. Since the 1990s the land subsidence due to the rapid urbanization has been considered a severely destructive hazard in the center of Hanoi City. Although previous studies and measurements have quantified the subsiding deformation in Hanoi center, no data exist for the newly established districts in the south and the west, where construction development has been most significant and where groundwater pumping has been very intensive over the last decade. With a multi-temporal InSAR approach, we quantify the spatial distribution of the land subsidence in the entire Hanoi urban region using ALOS images over the 2007-2011 period. The map of the mean subsidence velocity reveals that the northern bank of the Red River appears stable, whereas some areas in southern bank are subsiding with a mean vertical rate up to 68.0 mm yr −1 , especially within the three new urban districts of Hoang Mai, Ha Dong -Thanh Xuan and Hoai DucTu Liem. We interpret the spatial distribution of the surface deformation as the combination of the nature of the unsaturated layer, the lowering of groundwater in the aquifers due to pumping withdrawal capacity, the increase of built-up surfaces and the type of building foundation. The piezometric level in Q p aquifer lowers particularly after 2008, whereas the groundwater level in Q h aquifer remains steady, even if it loses its seasonal fluctuation in urban areas and drawdowns in neighboring water production plants. The time evolution deduced from the InSAR time series is consistent with previous leveling data and shows that the lowering rate of the surface slightly decreases till 2008. The analysis of groundwater levels in instrumented wells shows a correlation between the behavior of groundwater with the urban development and the acceleration of groundwater withdrawal. Also, the time variations suggest that the deformation became non-stationary, with upward and downward transient displacements related to the charge and discharge of the aquifers.
