A permeability pumping test was carried out in a confined aquifer with the piezometric level before pumping is 2.11 m. below the ground surface. The aquiclude (impermeable layer) has a thickness of 5.94 m. measured from the ground surface and the confined aquifer is 7.6 m. deep until it reaches the aquiclude (impermeable layer) at the bottom. At a steady pumping rate of 14.9 m³/hour the drawdown in the observation wells. were respectively equal to 1.61 m. and 0.43 m. The distances of the observation wells from the center of the test well were 16 m. and 32 m. respectively. Compute the depth of water at the farthest observation well. Compute the coefficient of permeability in mm/sec. Use 4 decimal places.

Transcribed Image Text:A permeability pumping test was carried out
in a confined aquifer with the piezometric
level before pumping is 2.11 m. below the
ground surface. The aquiclude (impermeable
layer) has a thickness of 5.94 m. measured
from the ground surface and the confined
aquifer is 7.6 m. deep until it reaches the
aquiclude (impermeable layer) at the bottom.
At a steady pumping rate of 14.9 m³/hour
the drawdown in the observation wells. were
respectively equal to 1.61 m. and 0.43 m.
The distances of the observation wells from
the center of the test well were 16 m. and 32
m. respectively. Compute the depth of water
at the farthest observation well. Compute the
coefficient of permeability in mm/sec. Use 4
decimal places.
