The grid on an aerial base map

UNESCO-IHE, Deltares and USGS have developed the San Francisco Bay Delta model within the Cascade II project applying the Deltares Delft3D FM (flexible mesh) software.

This website presents a web-based infrastructure around the SFBD model to stimulate and enhance knowledge and understanding of the Bay-Delta system. The SF Bay Delta community model is open access (publicly available, but only 2D in first instance) and the modeling software (Delft3D FM) will be released as open source. The web-based infrastructure will support active development by third parties.

Third parties are allowed to download and adapt the SFBD model for own use. Preferably, new versions of the model are downloaded again to this website for use by other parties. Third parties may develop a version of the model for own purposes. Once such a version is made available to another party, it should be made publicly available (for instance at this website). We aim to further develop a base mesh of the SFBD model in the trunk. Branches (for example, subdomains, more detailed mesh, water quality applications) may develop depending on project opportunities.
