Similarly, the pressure head drops and the soil displacement increases in confined aquifer I at all stages as shown in Figure 4.
In the present study the results of fifteen pumping tests, carried out on the confined aquifer of the Montalto Uffugo test field over several years, were considered.
Many studies have indicated that the nitrogen concentration is negatively correlated with the well depth (Majumder, Hasnat, Hossain, Ikeue, & Machida, 2008; Squillace et al., 2002; Townsend & Young, 2000) because the pollutants from human activities do not leach into the much deeper and confined aquifer (Bonton, Rouleau, Bouchard, & Rodriguez, 2010; Masetti, Poli, Sterlacchini, Beretta, & Facchi, 2008).
Estimate the discharge from a 0.3-m diameter well fully penetrating a confined aquifer given the following:
Increased pressure levels in the confined aquifer since the 1970s will also be a factor in the long-term balance, if low upward vertical groundwater gradients prevent downward groundwater flow (Timms 1997b).
The second confined aquifer is identified at a depth of 111-160 m, having moderate resistivity value of 81a|m with a thickness of 49 m and extending from VES-6 to VES-8.
Water pressure borne by floor strata from an underlying confined aquifer is no longer uniformly distributed water pressure but has a certain water pressure gradient along the dip direction for an inclined coal seam.
Especially in this study, the leakage of gaseous C[O.sub.2] into a shallow confined aquifer was considered.
West in Greenfield and is the site of three operational gravel-packed wells within a confined aquifer. These wells supply approximately 50% of the Towns drinking water.
(1987), for a homogeneous, isotropic, laterally extensive, and confined aquifer, the phase shifts between earth tides and water level are assumed to be caused by the time required for water flowing into and out of the well.
