<br />Following completion of this study a more vigorous analysis was =ade by <br /> <br /> <br />aimulating the area with a digital model. Two alternate plans of ground <br /> <br />water withdrawals were considered. The first plan withdrew 840,000 <br /> <br />acre-feet annually from 378 wells with the northern salvage areas producins <br /> <br />more water and decreasing the pumpage in the southern areas. The pre- <br /> <br />dicted drawdowns were small in comparison with the thickness of saturated <br /> <br />deposits in the area. The second analysis withdrew the same amount of <br /> <br />water from 100 wells whose yield was designed in proportion to local <br /> <br />aquU,r tnnBm1ssivity. The studies indicated that both arrangements <br /> <br />were superior to the Bureau's layout prese"~ed in the house document, <br /> <br />hewever, the as recognized that the Bureau's original design may not be <br /> <br />the best layout and indicated that the salvage project would be de"eloped <br />in s,tages and that the original well Layout should be as fiUd con.litiona <br /> <br />dictated. <br /> <br />, <br /> <br />Results from additional model testing in 1971. in which four cases of <br /> <br />project operatioll were tested, indicated (1) that: the project prop,)ul <br />1& feasible w1th water salvage. (2) that the river will not be sigaH1- <br /> <br />caDtly d-eplete4 by withdrawals frO'll1 wells, (3) that more water can be <br /> <br />salVaged by using larger weI1fields, and (4) that the well fields <br />should be designed with withdrawals made proportional to local trans- <br /> <br />mi,.ivity.
