The thickness of a horizontal, confined, homogeneous, isotropic aquifer of infinite areal extent is 30m. A well fully penetrating the aquifer was continuously pumped at a constant rate of 0.1 m³/s for a period of 1 day. The drawdowns given in the table below were observed in a fully penetrating well 90 m from the pumping well. Compute the transmissivity and the storativity by using: a) the Theis method of log-log matching. b) the Cooper-Jacob method of semi-log plotting. [For Part a), you have to first use attached Table to plot the values of W(u) versus 1/u on a log-log graph in the range of 10-9
