“…Existing studies have primarily focused on two aspects: land subsidence monitoring using various techniques supplemented by characteristic analysis and the evaluation of soil layer deformations (Bonì et al 2015;Cigna et al 2012;Galloway and Burbey 2011;Hung et al 2009;Shi et al 2007;Tomás et al 2013;Zhang et al 2014), and the numerical simulation and prediction of land subsidence induced by groundwater extraction (Chen et al 2003;Hung et al 2012;Kim and Parizek 2005;Yang et al 2015;Ye et al 2016). Regarding the former aspect, various methods employing ground-based and remotely sensed geodetic surveys are used for measuring and mapping spatial gradients and the temporal rates of regional and local subsidence as well as horizontal ground motion.…”

Land subsidence due to aquifer-system compaction accompanying groundwater extraction is a global hazard. Rising urban construction and groundwater demand necessitate increased awareness and better understanding of the geological problem. Motivated by the lack of laboratory-scale studies on this issue, an experimental investigation on the newly developed Tongchuan region, China, is presented. The study addresses the deformation behaviors of three soil samples, with the lithology of silty clay, silt, and fine sand, under the conditions of groundwater withdrawal and recharge using the GDS Consolidation Testing System. Results indicate that all three samples were characterized by elastic-plastic deformation under the conditions of withdrawing and recharging. The vertical deformation of the silty clay in the aquitard above the first confined aquifer was larger than those of the other two samples, and its deformation is a gradual and long process; thus, considerable attention should be paid to deformation in this aquitard due to the apparent creep effect and tiny rebound deformation. However, the settlement of the fine sand in the second confined aquifer cannot be ignored due to the great thickness of the aquifer. For the same soil, as the pore-water pressure declined, the unit rate of vertical deformation decreased gradually, whereas the creep effect of deformation in the later declining stage of pore-water pressure was more apparent than that in the former declining stage. These observations are highly important to the local government, which is developing measures to prevent and control subsidence.

“…The change in pore pressure is temporary, as the increased pressure diffuses horizontally and vertically through the aquifer system. Aquitards generally show more pronounced RWFs than aquifers and play key roles in generating RWFs because of slower head changes and faster mechanical changes across aquitards (Kim and Parizek , ). The terms “Noordbergum effect” and “Rhade effect” generally refer to poroelastically coupled responses in aquitards and aquifers at the start of pumping and the start of recovery, respectively.…”

Reverse Water‐Level Fluctuations Associated with Fracture Connectivity

et al. 2013

Reverse water-level fluctuations (RWFs), a phenomenon in which water levels rise briefly in response to pumping, were detected in monitoring wells in a fractured siliciclastic aquifer system near a deep public supply well. The magnitude and timing of RWFs provide important information that can help interpret aquifer hydraulics near pumping wells. A RWF in a well is normally attributed to poroelastic coupling between the solid and fluid components in an aquifer system. In addition to revealing classical pumping-induced poroelastic RWFs, data from pressure transducers located at varying depths and distances from the public supply well suggest that the RWFs propagate rapidly through fractures to influence wells hundreds of meters from the pumping well. The rate and cycling frequency of pumping is an important factor in the magnitude of RWFs. The pattern of RWF propagation can be used to better define fracture connectivity in an aquifer system. Rapid, cyclic head changes due to RWFs may also serve as a mechanism for contaminant transport.

“…The pumping well is drilled vertically through the confined aquifer and the pumping rate is set to -6 9 t/360 at x = 0. The hydraulic properties parameters of three aquifers are obtained from these references (Kim and Parizek 2005;Biot 1955;Leake and Hsieh 1997;Wang 2000;Hsieh 2006) and used in model as shown in Table 1.…”

“…There have been several experimental and mathematical studies on the permeability and pore-volume changes with pore water pressure and soil stress, such as Zimmerman (2000) believed an increase in temperature may lead to a large increase in fluid pressure, which will then give rise to mechanical stresses and strains. Kim and Parizek (2005) used a fully coupled poroelastic numerical model to simulate the hydraulic and mechanical responses when hydraulic pumping and pumping shutoff, the result showed that poroelastic deformation caused by groundwater pumping and pumping shutoff from an aquifer could induce noticeable reverse hydraulic head fluctuations. Ouria et al (2009Ouria et al ( , 2011) developed a numerical model to investigate the effect of the changes of the soil permeability on the transient seepage, the result showed that the effect of the change of the permeability on the outlet flow was different depending on the coupled or uncoupled formulations.…”

Simulation of fully coupled finite element analysis of nonlinear hydraulic properties in land subsidence due to groundwater pumping

et al. 2015

A fully coupled mathematical model of land subsidence caused by groundwater pumping was established based on the mechanics of porous seepage and the theory of fluid-solid interaction. The mathematical model employing the Galerkin finite element method was proposed to simulate the deformation dependencies of hydraulic properties due to the water pressure decrease in aquifers. This model has been verified by comparing with the known analytical solutions in the confined aquifer. Results show that the simulated drawdown and displacements match well with those of analytical solutions. To evaluate the nonlinear effects of hydraulic properties in the seepage and consolidation coupling phenomena, the numerical model is applied to an ideal three layers numerical experiment. The results show that the subsidence rate is faster than conventional groundwater theory when the nonlinear hydraulic properties (NHP) are considered in the coupled model. The reason is that the water level decline due to groundwater withdrawal induces the soil compression and the porosity and permeability decrease. Decrease of permeability in regions adjacent to the pumping well produces hydraulic gradient and seepage forces that may result in accelerated subsidence. Therefore, the effect of the NHP is an interaction process of pore water pressure and soil consolidation deformation and should not be ignored. Further studies of various hydrogeology problems are recommended to consider the heterogeneity concerning different stratigraphic condition in the field.
