“…Groundwater overdraft, which occurs when aquifer outputs (including groundwater extraction) persistently exceed inputs, has many negative consequences (Konikow and Kendy, 2005;Zektser et al, 2005;Werner et al, 2013;D€ oll et al, 2014). Overdraft has caused saltwater intrusion, subsidence, and permanent storage loss in California's aquifers (Galloway et al, 1998;Nenna et al, 2013;Faunt et al, 2016). California enacted its first statewide groundwater management legislation in 2014, the Sustainable Groundwater Management Act, which creates a framework for local agencies to bring groundwater basins into balance.…”

“…Because of its high sensitivity to vertical displacement, the InSAR monitoring of the human-induced subsidence phenomenon became one of the main applications (e.g., Massonnet et al, 1997;Fielding et al, 1998;Galloway et al, 1998;Lazecky et al, 2010), especially in urban areas where the number of coherent pixels over time remains high (e.g., Hoffmann et al, 2001;Watson et al, 2002;Stramondo et al, 2008;López-Quiroz et al, 2009;Crosetto et al, 2010;Crosetto et al, 2013). The decorrelation noise results either from a variation of the satellite LOS direction for the two images (different look and squint angles) or from a change of the scatterer position or geometry within the resolution cell.…”

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.

“…Annual pumpage for 1996 through 2005 was estimated by Siade et al (2014) Land subsidence and aquifer-system compaction Land subsidence is the loss of surface elevation as a result of the removal of subsurface support and is governed by the principle of effective stress and the theory of hydrodynamic consolidation (Terzaghi 1925). One of the principal causes of land subsidence is the gradual compaction of compressible aquifer systems resulting from declines in hydraulic head caused by groundwater pumping (Leake 1990;Galloway et al 1998Galloway et al , 1999. Some of the detrimental effects of land subsidence include the loss of aquifer storage, increased risk of flooding, cracks and fissures, damage to man-made structures, and other intangible economic costs.…”

Natural recharge estimation and uncertainty analysis of an adjudicated groundwater basin using a regional-scale flow and subsidence model (Antelope Valley, California, USA)

Groundwater has provided 50-90 % of the total water supply in Antelope Valley, California (USA). The associated groundwater-level declines have led the Los Angeles County Superior Court of California to recently rule that the Antelope Valley groundwater basin is in overdraft, i.e., annual pumpage exceeds annual recharge. Natural recharge consists primarily of mountain-front recharge and is an important component of the total groundwater budget in Antelope Valley. Therefore, natural recharge plays a major role in the Court's decision. The exact quantity and distribution of natural recharge is uncertain, with total estimates from previous studies ranging from 37 to 200 gigaliters per year (GL/year). In order to better understand the uncertainty associated with natural recharge and to provide a tool for groundwater management, a numerical model of groundwater flow and land subsidence was developed. The transient model was calibrated using PEST with water-level and subsidence data; prior information was incorporated through the use of Tikhonov regularization. The calibrated estimate of natural recharge was 36 GL/year, which is appreciably less than the value used by the court (74 GL/year). The effect of parameter uncertainty on the estimation of natural recharge was addressed using the Null-Space Monte Carlo method. A Pareto trade-off method was also used to portray the reasonableness of larger natural recharge rates. The reasonableness of the 74 GL/year value and the effect of uncertain pumpage rates were also evaluated. The uncertainty analyses indicate that the total natural recharge likely ranges between 34.5 and 54.3 GL/year.
