The static level of water table in an unconfined aquifer was 35m above the underlying impermeable stratum. A 75mm radius well, penetrating the aquifer to its full depth, was pumped at the rate of 28 liters per second. After several weeks of pumping, the drawdown in observation wells 20m and 50m from the well were 3m and 2.5m respectively, and the observed drawdowns were increasing very slowly. (B.Sc., UAE, 1989).a) Assuming equilibrium conditions, estimate the hydraulic conductivity and transmissivity of the aquifer.b) Estimate the drawdown just outside the pumped well.
) A pumping test carried out in a 50 m thick confined aquifer resulted in a flow rate of 600l/min. The thickness of the impermeable layer above the aquifer is 20 m and the originalwater level in the well was 2 mm below the ground surface (which is also the top of theimpermeable layer). Drawdowns in two observation wells located 50 m and 100 m fromthe well are 3 and 1 m respectively. Calculate:i) The coefficient of permeability of the aquifer, ii) The drawdown in the well, iii) The radius of influence. The diameter of the well is 0.6 m.
A groundwater pump has an unknown discharge extraction rate from a confined aquifer. The thickness is 8mand K=40m/day. To estimate its flow rate, 2 observation wells were installed. The first well is 2.5km from thepump and another well 6.9km from the first well further. The observed drawdown from original water level of150m were 12m in the 1st well and 7m in the 2nd well.

Observation wells were sighted at distances 4m and 9.5m from the pumping well. Using a discharge of 0.4 cubic meters per hour, a steady level is attained at the pumping well.
