“…Previous computer programs by Meyer and Carr (1979), Williamson and others (1989), Leake and Prudic (1991), and Hoffmann and others (2003) assume preconsolidation stress is related to a preconsolidation head. The preconsolidation head is used to switch between elastic and inelastic storage properties-specific storage changes to inelastic values whenever the hydraulic head falls below the preconsolidation head.…”

“…As of the release of this report, the SUB-WT Package is compatible only with MODFLOW-2000, andMODFLOW-2005, as is the SUB Package. Users of older versions of MODFLOW may use the Interbed Storage Package (Leake and Prudic, 1991) to simulate aquifer-system compaction.…”

“…For aquifer systems that include compressible fine-grained interbeds ( fig. 1), existing model programs have been modified to account for release of water from compacting interbeds and to compute resulting compaction 1 and land subsidence (Meyer and Carr, 1979;Williamson and others, 1989;Leake and Prudic, 1991;Hoffmann and others, 2003). These computer programs keep track of head at which preconsolidation stress will be exceeded (preconsolidation head).…”

“…This paper extends previous models by presenting a method for simulating aquifer-system compaction in models that include unconfined ground-water flow. A computer program developed to implement this approach expands on the earlier work by Leake and Prudic (1991). The program works as a part of the U.S. Geological Survey (USGS) modular finite-difference ground-water flow model, MODFLOW-2000and MODFLOW-2005(Harbaugh and others, 2000Harbaugh, 2005).…”

Land subsidence and uplift, ground ruptures, and induced seismicity are the principal geomechanic effects of groundwater withdrawal and injection. The major environmental consequence of groundwater pumping is anthropogenic land subsidence. The first observation concerning land settlement linked to subsurface processes was made in 1926 by the American geologists Pratt and Johnson, who wrote that ''the cause of subsidence is to be found in the extensive extraction of fluid from beneath the affected area.'' Since then, impressive progress has been made in terms of: (a) recognizing the basic hydrologic and geomechanic principles underlying the occurrence; (b) measuring aquifer compaction and ground displacements, both vertical and horizontal; (c) modeling and predicting the past and future event; and (d) mitigating environmental impact through aquifer recharge and/or surface water injection. The first milestone in the theory of pumped aquifer consolidation was reached in 1923 by Terzaghi, who introduced the principle of ''effective intergranular stress.'' In the early 1970s, the emerging computer technology facilitated development of the first mathematical model of the subsidence of Venice, made by Gambolati and Freeze. Since then, the comprehension, measuring, and simulation of the occurrence have improved dramatically. More challenging today are the issues of ground ruptures and induced/ triggered seismicity, which call for a shift from the classical continuum approach to discontinuous mechanics. Although well known for decades, anthropogenic land subsidence is still threatening large urban centers and deltaic areas worldwide, such as Bangkok, Jakarta, and Mexico City, at rates in the order of 10 cm/yr.
