“…In an integrated geophysical study using seismic, aeromagnetic and gravimetric data, Anderson et al (2004) presented a basin depth model, estimating depth to basement rock beneath the alluvial deposits, and a structural interpretation of the upper crust. Most recently, Danskin et al (2006) reported on an integrated analysis of the surface and groundwater systems, describing current computer models of the aquifer system, and suggesting water management plans for different usage forecasts and contamination plume remediation options.…”

“…A number of fault splays and minor faults are present in the San Bernardino basin (Fig. 2), many of which act as groundwater flow barriers (Dutcher & Garrett 1963; Woolfenden & Kadhim 1997; Anderson et al 2004; Danskin et al 2006). The study area spans all or part of four different municipal sub‐basins, the Bunker Hill basin, the Rialto‐Colton basin, the Chino basin and the Yucaipa basin (Fig.…”

S U M M A R YUsing InSAR and hydrogeologic time-series spanning 1995 to 2000, we characterize the elastic storage and surface deformation in the vicinity of the San Bernardino basin, California. The region encompasses a complex major aquifer located at the junction of the San Andreas and San Jacinto faults that supplies groundwater to over 600,000 people. We remove the elastic vertical surface displacement associated with changes in groundwater levels from the InSAR time-series by a least squares inversion. Our method estimates a poroelastic ratio at 60 well sites, which we normalize by basin depth, allowing for comparison of the elastic response of the aquifer skeleton from site to site. Our method also estimates residual vertical displacement rates at each well site, surface displacement not explained by observed trends in groundwater levels. Residual vertical displacement rates reveal patterns of subsidence and uplift across the basin over the 5-yr period from 1995 to 2000. In a narrow zone of observed residual subsidence near the San Jacinto fault, where many normalized poroelastic ratios trend higher than expected, we find permanent compaction of clay-rich strata to be the most likely explanation for 0.5-2.0 mm yr -1 of residual subsidence. This permanent compaction is likely a result of delayed compaction due to previous overdraft conditions and/or a result of the installation of deep production wells during the span of the InSAR time-series. Observations of localized subsidence within stepovers of the San Jacinto fault zone and relative uplift at the range fronts are consistent with current basin development models; however, interseismic strain modelling of the regional faults does not reproduce the surface displacement pattern or magnitude of these observations.

For a well in the vicinity of a surface water body, a formula is developed that relates the share of bank filtrate on total pumpage, that is, the discharge ratio, on one side, to basic well and aquifer characteristics on the other. The application of the formula is demonstrated for solving the inverse problem: for an aimed discharge ratio, well characteristics (pumping rate, distance to shore) can be determined. Other useful applications of the formula are outlined.
