Delft DFlow-FM Model of South San Francisco Bay Shoals

The Deltares Delft3D FM (flexible mesh) model of the Bay-Delta that provides boundary conditions for the South San Francisco Bay geomorphic model, which is now a 1D model that is spatially extrapolated to 2D, was released at the Bay-Delta Conference in October 2014. The San Francisco Bay-Delta Community Model is an open source Delft3D FM model and allows for continuous development of a process-based, hydrodynamic surface water flow model of the San Francisco Bay-Delta system. The domain covers an area from Point Reyes up to the tidal limits near Sacramento and Vernalis and includes the entire Bay. A high-resolution mesh ultimately allows for detailed computations of flow (including salinity and temperature), sediment transport (sand and mud transport, suspended sediment concentration, turbidity, morphodynamics), water quality (including turbidity, phytoplankton, nutrients, and contaminants) and ecosystems (habitat indicators). A publicly accessible web site supplies all the grids and software to run the model and post-process the output. The community model is developed through multiple funding sources including this LCC project and the USGS CASCaDE project.
