“…Artificial recharge after long-term groundwater extraction causes land uplift, which consists of elastic, plastic, visco-elastic, and visco-plastic components. In reality, the recoverable elastic and visco-elastic deformation accounts for a very small proportion of total deformation [18]. When the water level of a confined aquifer rises in the process of artificial water injection, the elastic deformation can recover quickly, while the recovery of visco-elastic deformation is time-dependent.…”

“…Over-exploitation of groundwater leads to a decrease of groundwater level. Although the confined aquifer is elastic, the continuous over-exploitation of groundwater leads to irrecoverable confined aquifer deformation, which further leads to land subsidence [18]. In order to study the spatiotemporal characteristics of subsidence and ground fissures, both global positioning system (GPS) and InSAR observations between 2005 and 2007 were employed [32,33].…”

“…Increasing effective stress leads to the compaction of hydrostratigraphic units and land subsidence ensues. Severe land subsidence due to extensive groundwater withdrawal has occurred in many areas worldwide, such as Las Vegas (Bell et al 2002), Venice (Teatini et al 2012), Bangkok (Phien-wej et al 2006), Taipei (Chen et al 2007), and Shanghai (Zhang et al 2015). Land subsidence results in a lot of damage to buildings and infrastructures, and loss of ground elevation.…”

Excessive groundwater withdrawal has caused severe land subsidence worldwide. The pore water pressure and the deformation of pumped hydrostratigraphic units are complex. A fully coupled three‐dimensional numerical simulation was carried out for different pumping plans in this paper. When groundwater is pumped from a confined aquifer, the great compaction occurs in the pumped aquifer and its upper and lower adjacent aquitard units. Land subsidence is smaller and the area affected by land subsidence is greater when groundwater is pumped from the deeper confined aquifer. The pore water pressure in the pumped confined aquifer changes immediately with pumpage. In the adjacent aquitard units, however, the pore water pressure increases in the early pumping time and decreases in the early recharging time. The decrease in the pore water pressure vertically spreads from the interface between aquitard and pumped aquifer to the other surface of the aquitard. The pumped aquifer compacts and rebounds immediately with pumping and non‐pumping or recharging actions, while the compaction and rebounding of the aquitard units clearly lag behind. The compaction of the adjacent aquitard unit first occurs near the interface between aquitard and pumped aquifer units, and the compaction zone spreads outward as the pumping goes on. The aquitards may expand vertically within some zones. Due to the inelastic deformation of soil skeleton, different pumping plans result in different land subsidence. For the same net pumpage, maximal land subsidence and horizontal displacement are the smallest for constant discharge and the greatest for recharge‐discharge cycle.

“…When compared with surface reservoirs, groundwater reservoirs have many advantages in no occupation of land, no immigration, less evaporation, and a simple structure. Nowadays, groundwater reservoir are used in three ways: (1) Conjunctive use of surface water and groundwater to augment groundwater resources [8]; (2) Recovering the cone of depression formed by over-exploitation of groundwater [9]; and, (3) alleviating land subsidence [10], soil erosion, and seawater intrusion, and other typical geo-hazards in coastal areas [11,12]. To solve the problem of regulation and storage of water resources, one of the key construction techniques is the diversion of infiltration system.…”

Abstract:To improve the efficiency of utilizing water resources in arid areas, the mechanism of artificial recharge effecting on groundwater reservoir was analyzed in this research. Based on a generalized groundwater reservoir in a two-dimensional sand tank model, different scenarios of the infiltration basin location and recharge intensity are designed to study how to improve the efficiency of groundwater reservoir artificial recharge. The effective storage capacity and the effective storage rate are taken as the main parameters to analyze the relation between recharge water volume and storage capacity. By combining with groundwater flow system theory, FEFLOW (Finite Element subsurface FLOW system) is adopted to set up the groundwater numerical model. It is used to verify the experiment results and to make deep analysis on the rule of water table fluctuations and groundwater movement in the aquifer. Based on the model, different scenarios are designed to examine the combined effect of recharge intensity and intermittent periods. The research results show that: the distance between infiltration basin and pumping well should be shortened appropriately, but not too close; increasing recharge intensity helps to enlarge the effective storage capacity, but it can also reduce the effective storage rate, which goes against the purpose of effective utilization of water resources; and, the recharge intensity and recharge duration should be given full consideration by the actual requirements when we take the approach of intermittent recharge to make a reasonable choice.
