A well penetrates an unconfined aquifer, with undisturbed water level (ho) equal to 21m. After pumping the well at a constant rate of Q = 0.07 m/s, the steady-state drawdown at distances of 45 m and 110 m from the well are 3 m and 1 m. respectively. Assume the void ratio as 0.2. Compute the hydraulic conductivity of the aquifer. 215.0 m/day what is the porosity 0.16 find the darcy velocity in m/day 69.4 m/day

In a field testing, the hydraulic gradient between two peizometers is 1.11, the area of flow is 4.08 m2 and the hydraulic conductivity of the aquifer material is 0.94 m/day, calculate the discharge in m3/day. Note that discharge cannot be negative
Yuri wants to determine the permeability of an aquifer The aquifer has a test well 300-mm in diameter with two observation wells A pumping test was conducted for 24 hours with the discharge being held constant at 5,608.7 m^3/day. The first one, 86 59 meters from the test well, has a draw-down of 0.81 meters. The second one, 48 meters from the test well, has a draw-down of 1.13 meters. The static water table penetrates the well to a depth of 28 meters. Determine the radius of influence of the aquifer in meters Round off to three decimal places.

Charyeong wants to determine the permeability of an aquifer. The aquifer has a 300 mm diameter test well that penetrates 27 m. below the static water table. After 24 hours of pumping at 61 liters/sec, the water level in an observation well 93.53 m. from the test well was lowered to 24.83 m. and the other observation well at 33.3 m. from the test well, was lowered to 23.02 m. Determine the coefficient of permeability of the aquifer in m/day.
Environmental Enginee... During a recuperative test, the water is pumped out 2.8 m initially and allowed to recuperate. It was observed that the water level rises by 1.45m in 80 minutes. If the diameter of the well is 3.45m, determine by what amount the diameter need to be increased to get a yield of 5 litre per sec under a depression head of 1.65m.
