Table 7. Computed ground-water budget for 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. All units are in cubic foot per second, rounded to nearest tenth]
