Digital filters were developed based on the computed water-level response to Earth tides in well 14A-25-1 and barometric pressure in all three wells, and these filters were used to compute the filtered water-level time series in tables 2 and 3 for wells 28A-25-1 and 28A-25-2, respectively, and in table 4 for 14A-25-1. The tables (1-4) and the development of the digital filters and filtering techniques are described in Appendix 2 of the associated publication (https://doi.org/10.3133/ofr20191063).

Developments in the assessment of regional subsidence provide more information to constrain analyses and simulation of aquifer-system compaction. Current popular approaches to simulating vertical aquifer-system deformation (compaction), such as those embodied in the aquitard drainage model and the MODFLOW subsidence packages, have proven useful from the perspective of regional groundwater resources assessment. However, these approaches inadequately address related local-scale hazards-ground ruptures and damages to engineered structures on the land surface arising from tensional stresses and strains accompanying groundwater abstraction. This paper presents a brief overview of the general approaches taken by the U.S. Geological Survey toward understanding aquifer-system...
