“…Many other studies have demonstrated the use of InSAR in identifying the influence of geologic structure on deformation attributed to groundwater discharge and recharge (e.g. Bawden et al 2001;Lu and Danskin 2001;Heywood et al 2002;Buckley et al 2003).…”

“…Previously unknown and poorly defined structural or lithostratigraphic controls on groundwater flow and (or) aquifer-system deformation have been identified and defined (e.g. Amelung et al 1999;Galloway et al 2000a;Bawden et al 2001;Lu and Danskin 2001;Valentine et al 2001;Bell et al 2002;Buckley et al 2003;Schmidt and Bürgmann 2003).

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.

“…Further, Hoffmann et al [2001] have used time series InSAR observations and water levels measured in wells to estimate spatially varying aquifer system elastic storage coefficients. Lu and Danskin [2001] and Bawden et al [2001] have employed InSAR to help define the structure of groundwater basins.…”

[1] We use land-subsidence observations from repeatedly surveyed benchmarks and interferometric synthetic aperture radar (InSAR) in Antelope Valley, California, to estimate spatially varying compaction time constants, t, and inelastic specific skeletal storage coefficients, S kv *, in a previously calibrated regional groundwater flow and subsidence model. The observed subsidence patterns reflect both the spatial distribution of head declines and the spatially variable inelastic skeletal storage coefficient. Using the nonlinear parameter estimation program UCODE we estimate compaction time constants between 3.8 and 285 years. The S kv * values are estimated by linear estimation and range from 0 to almost 0.09. We find that subsidence observations over long time periods are necessary to constrain estimates of the large compaction time constants in Antelope Valley. The InSAR data used in this study cover only a three-year period, limiting their usefulness in constraining these time constants. This problem will be alleviated as more SAR data become available in the future or where time constants are small. By incorporating the resulting parameter estimates in the previously calibrated regional model of groundwater flow and land subsidence we can significantly improve the agreement between simulated and observed land subsidence both in terms of magnitude and spatial extent. The sum of weighted squared subsidence residuals, a common measure of model fit, was reduced by 73% with respect to the original model. However, the ability of the model to adequately reproduce the subsidence observed over only a few years is impaired by the fact that the simulated hydraulic heads over small time periods are often not representative of the actual aquifer hydraulic heads. Errors in the simulated hydraulic aquifer heads constitute the primary limitation of the approach presented here.

“…(20 millimeters, mm) relative to areas northwest and southwest of the facilities. Land surface displacements related to rising groundwater levels in recharge areas has been demonstrated in other areas of California (Galloway and others, 1999;Lu and Danskin, 2001;Bawden and others, 2001). These displacements may be a cause for concern in urban areas or may indicate potential for permanent (inelastic) subsidence of aquifer deposits should groundwater pumping lower water levels beyond previous levels (Galloway and others, 1999).…”
