A fully penetrating well with diameter of 0.25 m is bored into an unconfined aquifer with hydraulic conductivity of 22 m/d and porosity of 0.3. The water table is initially at a height of 55 m above the bottom of the aquifer. After continuous pumping, a steady state drawdown of 12 m is reached. (a) If the pumping rate has no effect on the water table at a distance of 1.2 km from the pumping well, determine the pumping rate. Determine the drawdown in an observation well 600 m away from the pumping well.  Determine the travel time from the observation well to the pumping well.

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.
