摘　　要：In this paper,the hydrogeological parameters of a confined aquifer,such as transmissivity(T),storativity(S)and radius of influence(R),have been assessed using real groundwater level measurements recorded by a monitoring network,consisting of automated municipal water supply boreholes at Nea Moudania aquifer,Chalkidiki,Greece.Particularly,the paper focused on the correlation between the drawdown and the constant flow rate during pumping time.So the Cooper-Jacob and the recovery test method were applied in order to delineate if turbulent head losses occur,as well as the impact of incorrect measurements of the radial distance(r)in the accuracy of estimating S values.The results show that a)the occurrence of a linear correlation between s and Q indicates a negligible turbulent head loss in the pumping wells and thus a reasonable flow rate usage,b)the validity of storativity values could be compromised if the r value is not accurately measured,and c)recovery test method can be used as an indicator of residual drawdown(s’)caused by previous pumping cycles,when the straight line intersecting the logarithmic t/t’axis has a value greater than 1.
