The data was used to model changes in the estuary based on projected sea level rises of 0-90 cm and projected air temperature increases of 0-4{\textdegree} C to show potential changes from the present to the year 2100. The upper estuary was shown to be the most vulnerable to climate change. Rising sea level, a factor not considered in previous studies, may moderate the effect of climate change on the lower estuary.}, pages = {p.136-146}, keywords = {Blodgett (Or.), Chitwood (Or.), climate, Elk City (Or.), Elk Creek, Hatfield Marine Science Center, mathematical modeling, Newport (Or.), sea level, Toledo (Or.), water quality, water temperature, Yaquina Bay, Yaquina River}, doi = {doi:10.1016/j.ecss.2015.11.006 }, url = {https://ir.library.oregonstate.edu/concern/articles/3r074w80k}, author = {Brown, Cheryl A. and Sharp, Darrin and Mochon Collura, T.
