Question: A livestock farm manager in area X is using pumping test results given in to tender for the construction of a well on his farm.

A livestock farm manager in area X is using pumping test results given in  to tender for the construction of a well on his farm. Further information revealed that the pumping test was done at a uniform rate of 28.9 liters/sec in a well penetrating a confined aquifer and drawdowns were recorded in an observation well 60m away. Using the unsteady confined aquifer equation:


a] Compute the following aquifer parameters and explain the importance of the computed parameters: (i) Transmissivity (ii) Storage coefficient 


b] Explain why values of drawdown are not good indicators for understanding the behaviour of aquifer flow dynamics for research or water supply.
