The aim of this study is to analyze pumping test data of Phulambri watershed area from Aurangabad District, Maharashtra (India) by using cooper-Jacob's time drawdown approximation of Theis method to estimate the aquifer parameters. In the present study, total of 04 aquifer performance test were conducted at different locations within the shallow basaltic aquifers. The advantage of this method is that, it is validation for any stepped pumping. The output of this research is that, the method can be used for estimating the pre-monsoon and post-monsoon efficiency of the wells. In the study area, the dug wells are in the depth ranged from 7.00 to 17.00 m and the diameter of the wells is between 2.70 to 4.50 m. The aquifer performance results seen that transmissivity values of the wells is varies from 3.25 to 446.21 m²/day (pre monsoon 2013) and 10.84 to 510.33 m²/day (post monsoon 2013). Storativity values of studied wells were observed varies from 0.0047 to 0.17 (pre monsoon 2013) and 0.0093 to 0.319 (post monsoon 2013). Whereas the specific yield of the wells is varies from 0.47 m3/ day to 11.13 m3/ day in winter (post monsoon) and 1.59 m3/ day to 31.96 m3/ day in summer (pre monsoon). The present study is useful to identify seasonal variation in drawdown and recuperation through numerical and graphical presentation.
