Numerical simulation of the Noordbergum effect resulting from groundwater pumping in a layered aquifer system

A fully coupled finite element analysis of water-table fluctuation and land deformation in partially saturated soils due to surface loading

“…The poroelastic governing equations for groundwater ow in deforming variably saturated porous media may be written as [8][9][10][11][12][13][14][15][16][17][18][19] …”

“…Accordingly, Biot's linear consolidation theory has further been developed into a general non-linear consolidation theory to consider the entire saturated-unsaturated ow regime by others [8][9][10][11][12][13][14] using a modiÿed e ective stress concept. A variety of numerical studies [15][16][17][18][19] has also used this non-linear consolidation theory to analyse land deformation due to groundwater pumping from partially saturated porous media. Results from these studies have provided more insightful interpretations on consolidation behaviour of partially saturated porous media under groundwater pumping.…”

Numerical simulation of the Rhade effect in layered aquifer systems due to groundwater pumping shutoff

“…The Noordbergum effect was then simulated quantitatively by Hsieh [11] and Kim and Parizek [20] based on poroelasticity theory, which was proposed first by Biot [4]. Hsieh [11] first simulated the Noordbergum effect in two different fully saturated confined layered aquifer systems using a linear poroelastic numerical model.…”

Vertical movement of water in a High Plains Aquifer induced by a pumping well

“…According to Kim and Parizek (1997), the Noordbergum effect is caused by two mechanisms: a faster mechanical propogation (deformation) of the pumping stress than its hydraulic propogation (drawdown) from the pumped aquifer into the adjacent aquitard and unpumped aquifer due to relatively lower hydraulic conductivity of the aquitard, and a mechanical amplification in the lower part of the relatively soft aquitard.…”
