1. Executive Summary The San Francisco Bay Simulation Model (SFBayModel) is a high-resolution, three-dimensional hydrodynamic and transport model of the San Francisco Bay-Delta estuary. Developed primarily for understanding and predicting water circulation, salinity intrusion, sediment transport, and the dispersal of waterborne constituents (e.g., pollutants, larvae, heat), it serves as a critical tool for water resource management, environmental restoration, and regulatory compliance in one of the most complex and economically significant estuaries in the world. 2. Introduction & Background The San Francisco Bay-Delta system (including Suisun Bay, San Pablo Bay, Central Bay, and South Bay) is the largest estuary on the Pacific Coast of the Americas. It supplies drinking water to over 27 million California residents, supports billions of dollars in agriculture, and provides critical habitat for numerous threatened and endangered species (e.g., Delta smelt, Chinook salmon).
