Preliminary steady-state modeling calibrations of Tucson Water's Central Well Field flow model Tucson Basin, southeastern Arizona.

摘要

This study reviews the assumptions, the assembled data, and the considerations involved in calibrating a preliminary steady-state model of the City of Tucson’s Central Well Field. This study introduces a hydrostratigraphic characterization of basin sediments and develops a new set of aquifer parameter data. The results of two preliminary steady-state calibrations are presented based on assumed steady-state conditions in the early 1900s and quasi-steady-state conditions in 1940. Transient stresses over a 50-year period are imposed onto the results of the 1940 steady-state simulation to identify major deficiencies in the preliminary calibration.
