Show All twenty two well sites are generally in operation. The number of well sites in operation decreases as the drawdown level increases. The drawdown patterns for 2 levels of drawdown at QPmax of 6 m3/ day are shown in figures 2.5 and 2.6. The patterns are symmetrical with uniform drawdown across the dewatered area, except along the edges of the study area. These results are similar to those presented by Aguado, et al ( 1974) for a dewatered area. 60 50 ko o • e g- 20 3 10 • QPMAX* 1 » 3/ day • QPMAX* 2 • QPMAX* k • QPMAX* 6 _ L 11.5 11- 6 11.7 11.8 11.9 12.0 ' Dr » V4ovrt-' Level, meters 12.1 12.2 Figure 2.4 Total Pumpage vs Minimum Drawdown required for linear objective function 22 |
