“…Moreover, it is more expensive to regulate the total performance of aquifer tests. Although the data and equations have applied to identify the transmissivity with its inherent limitations and errors as potential (Gahala, 2015). Partial penetration of well, well loss and hydrogeological boundaries, values of transmissibility that have been calculated from specific capacity data by underestimate of actual values effect on the pumping tests unfavorably (Misstear & Beeson, 2000).…”

The hydrogeological investigation of south-eastern coastal aquifer of Bangladesh has been performed for the evaluation of well performance in the aquifer based on well logs and step-drawdown tests. The consequences from four single-well of stepdrawdown tests have conductd in two recent boreholes through Jacob and Rorabaugh's methods. From lithological data analysis it is observed that the aquifer of studied area is in Early Miocene age which consists of Upper and Middle Boka Bil formation. The values of step-drawdown test results have indicated well losses ranges between 17% and 19.8% and loss of aquifer on two well ranges between 82.6 % and 80.2% which reflected higher efficiencies of two wells. The values of specific capacity have varied from two wells in totally 18.13 m3/day/m to 23.79 m3/day/m, respectively whereas the values of well efficiency varied from 95.3% to 98.5% which indicate that the wells are properly developed and designed. The estimation of aquifer transmissivity ranges from 271.24 (m2/day) to 263.3 (m2/day) and these values have evaluated the wells indicating the higher production with its water accessibility from the wells. Therefore, it is indicated the laminar flow of the aquifer/well-face (negligible part of turbulent flow). As a result, the water-bearing zone is effective for high amount of water production per day. The total approaches of litholog and pumping tests determine the effective application of the single-well on step-drawdown tests and it has identified the safe and sustainable well growth for the extraction of groundwater in future.

“…Until the drawdown stabilized, it is measures every test temporary changes in water levels at every step (Kruseman, De Ridder, & Verweij, 1970). Moreover, some researchers (Gahala, 2015;Louwyck, Vandenbohede, & Lebbe, 2010) studied that the analytical process of step-drawdown test assists to identify the quantify aquifer mechanisms which evaluate the rate of flow into the well laminar/turbulent. The discharge rate (Q) and time are proportional to the resistance of formation on the water-bearing zone.…”
