Table 5. Specified infiltration and pumping rates for the 12 stress periods used in test simulation 2.
[English units used for test simulation 2 are consistent with units of example problem as described by Prudic and others (2004) and were not changed to conform to the Standard International units used elsewhere in this document. Infiltration rate was multiplied by the area of each cell (2.5 × 108 square feet) and by a factor that ranged from 1 to 8. Pumping rate was assigned to 10 model cells (appendix 2). Abbreviations: ft/s, foot per second; ft3/s, cubic foot per second]
