This report presents results derived from a numerical model of the ground-water flow system in the Portland Basin, Oregon and Washington, that was used to test and refine the conceptual understanding of the flow system, estimate the effects of past and future human-caused changes to ground-water recharge and discharge on ground-water levels and streamflow, and determine priorities for ground-water monitoring and data collection that would facilitate improvements in the utility and accuracy of the model.
