t (min) 11 14 1. In a horizontal, confined, homogeneous and isotropic aquifer, a well pumps at a constant rate of 15.5 l/s. An observation well, 30 m from the pumping well yielded the drawdown (s) observed at various observation times (t) after start of pumping as shown in the table. Plot on a semilogarithmic graph and use the Jacob method on the early data to calculate transmissivity (T) 21 and storage coefficient (S). 18 28 35 52 60 74 88 2. What do you notice in slope of the plotted data? What kind of boundary is indicated by the break in slope? In this case, how many image wells must be needed to provide an equivalent aquifer of infinite extent? Draw a sketch showing a possible configuration of pumping well, image well(s), and boundary, indicating whether the image wells are pumping wells or recharge wells. 100 112 130 s (m) 2.13 2.27 2.44 2.50 2.68 2.80 3.11 3.29 3.41 3.70 3.86 4.01 4.14
