Pumping-test data were <br />' graphically fitted to Type curves for aquifer response in an <br /> unconfined aquifer taken from Newman, 1975 . The aquifer param- <br /> eters of transmissivity (T) and storativity (S) were then <br /> calculated by the program. <br />' Recovery test data were analyzed based on the Theis equation <br /> as presented by Todd, 1980. Curve Match graphs, and drawdown <br /> data are included in Appendix V. Table 3 presents the trans- <br /> missivity (T) and storativity (S) values obtained from drawdown <br />' data analyses. <br /> TABLE 3 <br /> DRAWDOWN DATA ANALYSES RESULTS <br /> PUMP TEST <br /> Monitoring T Storativity Assumption in unconfined <br /> Well ft?/day (S) Aquifer Response <br /> 1 493 . 9 . 039 Elastic <br /> 1 1 731. 5 . 041 Delayed <br /> 4 36.79 3 x 10-7 Elastic <br /> 4 54. 40 2 .9 x 10-7 Delayed <br /> 2 40. 46 1. 05 x 10-5 Elastic <br />' RECOVERY TEST <br /> RW-1 27 . 22 <br />' 4 1035 . 28 * - <br /> ' * Representative values of storativity cannot be calculated using <br /> recovery data <br /> ® GRpUNDyVATER <br /> TECHNO[OCY,INC <br />
