The Marine Sciences Laboratory of Pacific Northwest National Laboratory (PNNL) has developed three-dimensional (3-D) hydrodynamic models for several estuaries and coastal basins in Puget Sound to support restoration projects, and has initiated a model development effort for the entire Puget Sound. The Northwest Straits Marine Conservation Initiative, authorized by Congress and guided by the Northwest Straits Citizen Advisory Commission (NWSC), is nationally recognized as an innovation that brings sound science and an ecosystem perspective together through the actions of seven marine resources committees. To support PNNL's effort of model development for Puget Sound and the straits, NWSC funded PNNL for the model validation and application components of the study. This report summarizes the development, validation, and application of the Puget Sound hydrodynamic model.
