Analysis of Pumping Test Data from Abstraction Well

In many situations pumping tests are carried out without observation well and drawdown/recovery, data recorded in the pumped well itself. Although, the time drawdown/recovery data are, being precisely recorded in the pumping well, the interpretation of such data often gives ambiguous results due to non-accountabiiity of well loss and well storage in many situations. This is particularly true in the case of low permeable aquifer. In order to overcome such difficulties, finite difference, method is used to estimate aquifer parameters. Field examples are presented to illustrate the above method.
