A digital model for simulation of ground-water hydrology in the Houston area, Texas

MODFLOW Ground-Water Model - User Guide to the Subsidence and Aquifer-System Compaction Package (SUB-WT) for Water-Table Aquifers

“…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.…”

“…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).…”

Summary of hydrology of the regional aquifer systems, Gulf Coastal Plain, south-central United States

“…Examples include simulation of water levels in an alluvial aquifer adjacent to a reservoir in eastern Texas (Garza, 1974); simulation of decline in water levels due to widespread ground-water withdrawals in southern Texas (Klemt and others, 1976); simulation of stream-aquifer interactions in Arkansas (Reed and Broom, 1979); simulation of declines in potentiometric surfaces of aquifers and land subsidence in the Houston area, Texas (Meyer and Carr, 1979;Carr and others, 1985); and simulation of water-level rises due to construction of navigation facilities on the Red River in northern Louisiana (Ludwig and Terry, 1980;Rogers, 1983). Simulations were made of water-level declines due to large ground-water withdrawals for northeastern Arkansas (Broom and Lyford, 1981); for the Memphis area, Tennessee (Brahana, 1982); for northwestern Mississippi (Sumner andWasson, 1984a, 1984b); for the Baton Rouge area, Louisiana (Torak and Whiteman, 1982;Huntzinger and others, 1985;Kuniansky, 1989); and for the Gulf Coastal Plain of Texas (Carr and others, 1985).…”
