A confined aquifer is recharged by a continuous supply of water from the certain source. The average thickness of the aquifer was determined to be 25 m and the average width is 4 km. The hydraulic conductivity of the aquifer was obtained at 40 m/day and its void ratio is 0.3333. The piezometer heads in two wells 1.325 km apart are 65 meters and 60 meters from a common reference datum. Determine the rate of flow in cubic meters per day.

1. A confined aquifer is recharged by a continuous supply of water from the certain source. The average thickness of the aquifer was determined to be 18 m and the average width is 8 km. The hydraulic conductivity of the aquifer was obtained at 60 m/day and its void ratio is 0.1586. The piezometer heads in two wells 2,145m apart are 128 meters and 188 meters from a common reference datum. Determine: •compute the rate of flow through the aquifer in m3/day •compute the seepage velocity in m/day •compute the time of travel from the head of the aquifer to a point 8 km downstream in days
A well penetrates an unconfined aquifer. Prior to pumping the water level(head) is ho = 25m after a long period of pumping at a constant rate of 0.05 m^3/s the drawdowns at distances of 50m and 150 m from the well were observed to be 3 m and 1.2 m respectively. Compute the hydraulic conductivity of the aquifer and the radius of influence of the pumping well. What type of deposit is the aquifer material?
A well is fully penetrated into a 27 m thick layer of sand which is underlain by a rock layer below the static water table. After 24 hours of pumping at 50 liters per second, the water level in an observation well at a distance of 0.10 km from the test well is lowered 50 cm. At another test well located 5000 cm from the test well, the water level dropped by 1000 mm. 1. Evaluate the coefficient of permeability (K) in cm per day? 2. If K 1.15 cm/sec, what should be the rate of discharge (q) in ( lit/sec)?
