Question
thumb_up100%
A 9.15m thick layer of sandy soil overlies an impervious rock. The groundwater level is at a depth of 1.22m below the top of the soil. Water was pumped out of the soil from a central well at the rate of 5680 kg/min and the drawdown of the water table was noted in two observation wells. These two wells were on a radial line from the centre of the main well at distances of 3.05m and 30.5m. During the pumping the water level in the well nearest to the pump was 4.75m below ground level. In the furthest well was observed to be 2.13m below ground level.
- Make a sketch of the situation explained in the foregoing and indicate what kind of aquifer is being described.
- Evaluate the permeability of this aquifer in m/day.

- Need answer ASAParrow_forward9) A well is located in a confined aquifer near the intersection of a constant head and impervious boundary. a) Estimate the steady state drawdown in the well for Q=2 ft³ s, rw = 1 ft, distance from the well to stream= 300ft and distance from well to impervious boundary= 150 ft. T = 0.14ft²/s b) Estimate the steady state drawdown at point P located midway between the well and the steam. The angle between the stream and the impervious boundary is 90°arrow_forwardA field pumping test was conducted from an aquifer of sandy soil of 4 m thickness confined between two impervious strata. When equilibrium was established, 105 liters of water was pumped out per hour. The water elevation in an observation well 3.50 m away from the test well was 2.1 m and another 6.0 m away was 2.7 m from the roof level of the impervious stratum of the aquifer.
