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).

The model solves the Reynolds-Averaged Navier-Stokes (RANS) equations with the Boussinesq and hydrostatic approximations (though non-hydrostatic options exist for localized flows). Salinity and temperature are transported as passive (but density-influencing) scalars. sfbaymodel

The model predicted a 30% increase in salt load at Mallard Island under April 2021 low-flow conditions (3,500 cfs) compared to average April flows (25,000 cfs). Verified by field data within ±8% error. The San Francisco Bay-Delta system (including Suisun Bay,

By coupling hydrodynamic runs with sea-level rise projections (0.5–2.0 m by 2100), the model predicts: Salinity and temperature are transported as passive (but

Today, the Bay Model serves as a premier educational facility and museum in Marin County. Admission is free, making it a "hidden gem" for residents and tourists alike. Bay Model Visitor Center
