This thesis uses numerical modeling to investigate circulation and transport in two major river plume systems, the Columbia and Fraser Rivers. Model sensitivity to advection scheme selection and wind forcing was evaluated using the SELFE model within the CORIE framework and validated against observations. Results show that the Upwind Method produced more accurate plume salinity distributions than the Eulerian–Lagrangian Method. These findings highlight the importance of modeling choices for improving simulation accuracy and supporting effective coastal management. 000000052 540__ $$fCC BY 000000052 542__ $$fIn copyright - single owner 000000052 650__ $$aEstuaries$$040221 000000052 650__ $$aEcosystem$$030218 000000052 650__ $$aEstuaries$$040221 000000052 651__ $$aBritish Columbia$$040924 000000052 651__ $$aOregon$$041094 000000052 651__ $$aPacific Northwest$$044288 000000052 651__ $$aUnited States--Columbia River$$044429 000000052 651__ $$aWashington$$041180 000000052 6531_ $$amathematical models 000000052 6531_ $$afraser river 000000052 6531_ $$acoasts 000000052 6531_ $$aplumes 000000052 6531_ $$aselfe 000000052 6531_ $$amodeling 000000052 691__ $$aOGI School of Science and Engineering$$041365 000000052 692__ $$aDepartment of Environmental and Biomolecular Systems$$041414 000000052 7001_ $$aKilgren, Ryan$$uOregon Health and Science University$$041354 000000052 7201_ $$aBaptista, António$$uOregon Health and Science University$$041354$$7Personal$$eAdvisor 000000052 8564_ $$9ce79412c-909a-47ae-b40d-21e8aefa3ae2$$s10432551$$uhttps://digitalcollections.ohsu.edu/record/52/files/52_etd.pdf$$ePublic$$22d03f4d67a80e894c6bdd65478a9a6db$$31 000000052 901__ $$a<p>These documents are archival records.
