..., two pumping tests were conducted during this field investigation. Although these wells were not ideally designed for aquifer performance tests (CGWB, 1986, 1992), the details of these wells along with the results obtained by applying the Jacob’s formula are given in table 5 . The drawdown data from...

... on the mobility of aquifer water are analyzed. The results show that the mobility of aquifer water is affected by the pore compressibility of formation rock and its elastic expansion. The proportion of movable water per unit drawdown pressure is 0.1%/MPa, which has little relationship with the production pressure...

... to tunnelling, the drawdown at the well locations was determined. From the drawdowns and using Dupuit's equation, the depletion of well flow rates after tunnelling was estimated. To evaluate the results, observed well flow rates before and after tunnelling were compared with the predicted flow rates...

... of this is that carbonate weathering, which results in no net change to atmospheric CO 2 levels over geological timescales ( Kasting 2019 this issue), can lead to drawdowns of CO 2 that are significant over the timescales of anthropogenic climate change. The above accounting of weathering pathways assumes that carbonic...

.... The results show that the scheme can keep the water table at the desired levels over a limited area. The maximum predicted nodal drawdowns after one year of pumping at 16 835 m 3 d –1 were 4.2 and 5.24 m in the two areas. Further investigations are proposed with the objective of optimizing pumping rates. ©...

... implementation of dewatering ( Edwards et al. 1991 ). Since the last test, the base of the quarry and drawdown levels had been doubled, increasing the impact on groundwater levels in the aquifer. The study sought to investigate the impact of this increased dewatering on the aquifer–conduit interaction...

The maximum late-time drawdown at the well is approximately 15 m (49 ft) for the specified head boundary condition (10 −13 line, Figure 11A ) and 27 m (88 ft) (10 −13 line, Figure 11B ) for the no-flux boundary. The former response is largely controlled by aquifer horizontal permeability and the distance...
