When the straight line intersects the x axis, s = 0 and the time is to. Substituting these values in Equation 9.8(12) gives

2.3Q 2.25Tto

0 = 55Tlog55

2.25Tto and


Example: Figure 9.8.3 shows that to = 1.6 X 10~3 days and slope As = 0.181. These values yield T = 1011 m2/d and S = 0.00009, which agree with the values for T and S obtained by the Theis solution.


The drawdown measurements s are plotted against distance r at a given time t as shown in Figure 9.8.4. From similar considerations as in drawdown-time analysis
