| Abstract | Long Description |
Puget Sound basins experience low oxygen levels that do not meet state water quality standards established under the federal Clean Water Act (CWA) to protect aquatic life. A primary concern regarding impairment of Puget Sound is to what extent human and natural sources contribute to low levels of dissolved oxygen in the bays and inlets of the Sound. The Washington State Department of Ecology (Ecology) is developing Puget Sound 2.0, the next generation analytical tool focused on circulation and dissolved oxygen dynamics. Puget Sound 2.0 will be used to evaluate impacts of changing human and climate influences. The Environmental Protection Agency (EPA), Pacific Northwest National Laboratory (PNNL), University of Washington Climate Impacts Group (UW-CIG), and Ecology have jointly initiated this water quality model development project to address the following nutrient management questions. Are human sources of nutrients in and around Puget Sound significantly impacting water quality? How much do we need to reduce human sources of nutrients to protect water quality in Puget Sound? The model simulates full eutrophication kinetics and has been calibrated using data collected in Puget Sound during 2006. The calibrated model, using best available information, will simulate the effects of future nutrient-loading, population growth, and climate change for calendar years 2020, 2040, and 2070. The specific objectives of Puget Sound 2.0 are to: --Refine the calibration of the water quality model to conditions observed in 2006. --Evaluate sensitivity of the model to various input parameters and boundary conditions. --Apply the model to a series of future climate and human scenarios to identify and quantify potential impacts. Findings from this study will be communicated through detailed project reports and web-based materials for both scientists and the general public. |
