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.

Question

A 30 cm well is pumped at the rate of 1000 ipm.
The transmissibility of the aquifer is o.015 m²/s.
If the well is located at a distance of 120 m from
a stream, what should be the drawdown?
(i) In the pumping well-
(ii) In an observation well 80 m away from the
pumping well on the side opposite to the
stream?
(iii) In an observation well 80 m away from the
pumping well, on a line parallel to the stream?

a) A well for extracting water from a confined aquifer was installed at a site. The top of the confined aquifer was at a depth of 10 m and the bottom was at a depth of 17 m. When the well was first installed the water level rose to 3 m below the ground surface, prior to the installation of any pumps. Observation wells were installed 50 m and 150 m radially out from the centre of the extraction well. i) At a pumping rate of 3000 litres/hour the water levels in the observation wells were 5 m and 4 m below the ground surface, respectively. Calculate the coefficient of permeability of the confined aquifer. ii) Calculate the radius of influence of the extraction well. iii) What is the minimum depth that the observation wells would have to be installed to?

There are two identical groundwater pump facilities that is operating 6 kilometers apart. The hydraulic conductivity is 40m/day. Each pump well structure has a tube diameter of 75cm. The original water table has an elevation of 110 m. However, it is maintained that the maximum drawdown (at the tube) is 18m. The water table will not change at the midpoint between the two pump wells. Determine the drawdown at a point 2 km from the pump.
