“…Many studies have demonstrated that surface displacements related to aquifer-system deformation accompanying groundwater discharge and recharge are not only common, but can be measured reliably in spatial and temporal detail (e.g. Galloway et al 1998;Amelung et al 1999;Hoffmann et al 2001Hoffmann et al , 2003aWatson et al 2002;Schmidt and Bürgmann 2003;Ferretti et al 2004;Canuti et al 2005).…”

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.

“…Installing and maintaining even a limited number of continuous GPS and CMW stations to resolve the spatial resolution of local land subsidence is costly. Differential interferometric synthetic aperture radar (DInSAR) is an alternative for mapping the spatial distribution of land subsidence at a relatively high resolution (Galloway et al 1998;Hoffmann et al 2001Hoffmann et al , 2003Calderhead et al 2011). This approach has been applied in quantifying land subsidence in many areas of Taiwan (e.g., Chang et al 2004;Hung et al 2010).…”

Precise leveling, global positioning system (GPS), and interferometric synthetic aperture radar (InSAR) have had marked influences on the geodesy field. Many studies have applied these techniques to land subsidence monitoring and predictions. Land subsidence in the Choushui River Fluvial Plain (CRFP) in western central Taiwan is severe, primarily because of excessive groundwater pumping. Exploiting various observational techniques this study employed a geostatistical cokriging algorithm to integrate multiple types of observations for mapping land subsidence in the CRFP between 1993 and 2008 to effectively reduce the regional effects and interpolation biases in InSAR observations. Precise leveling data and persistent scatterer InSAR results were first assessed through variogram analysis, the results of which revealed similar directional variograms and no nugget effect for the experimental variograms. All observed sill values decreased with increasing temporal intervals and the ranges of the same type of observations tended to be stable for time intervals of different lengths. The accuracy of a cokriged land subsidence map was verified using continuous GPS data at the same cell locations and was significantly improved compared to when the precise leveling data were used. The cokriging interpolations of land subsidence in the CRFP indicated that the severe subsidence areas had moved from the coastal area to the central CRFP. An obvious critical subsidence migration point for the southern CRFP occurred in 1998. Overall subsidence rate trends increased in the early periods (1993 -1998 and 1998 -2003) and decreased in the most recent period (2005 -2008).

Estimating temporal changes in hydraulic head using InSAR data in the San Luis Valley, Colorado

The sustainability of the confined aquifer system in the San Luis Valley, Colorado is of utmost importance to the valley's agricultural economy. There is a dearth of hydraulic head measurements in the confined aquifer to which the current groundwater flow model can be calibrated. Here we investigate the extent to which spatially and temporally dense measurements of deformation from Interferometric Synthetic Aperture Radar (InSAR) data can be used to fill in spatial and temporal gaps in the head data set by calibrating the InSAR data with head at the monitoring well locations. We conduct this calibration at 11 wells where we expect sufficient deformation for reliable InSAR measurement, given the accepted level of uncertainty ($1 cm). In the San Luis Valley, crop growth degrades the quality of the InSAR signal, which means that the high-quality deformation data may not be collocated with the wells. We use kriging to estimate the deformation directly at the well locations. We find that the calibration is valid at three well locations where the seasonal magnitude of the deformation is much larger than the uncertainty of the InSAR measurement. At these well locations, we predict head prior to and within the temporal sampling window of the head measurements. We find that 59% of the InSAR-predicted hydraulic head values agree with the measured values, within the uncertainty of the data. Given our success in extending the hydraulic head data temporally, the next step in our research is to use InSAR data to interpolate spatially between head measurements.
