Flow Science is the custodian of the Fischer Delta Model (FDM) which has the capability to model complex bay-estuary-channel systems. It is used extensively for predicting salinity conditions in the Sacramento-San Joaquin River Delta in California. The model can predict flows, salinity transport, and the dispersion of pollutants and tracers.

The FDM consists of two programs, one for determining flows and one for predicting salinity or tracer dispersion. Both models have been well calibrated over the past 15 years and validated by extensive field testing in the Sacramento-San Joaquin Delta. In addition to having extensive historical data sets, results from the Department of Water Resources' DWRSIM model can be directly input into the FDM.

Flow Science has used the FDM to specifically perform analyses as part of NPDES permitting processes, for State Water Resrouce Control Board studies, and for many private firms and government agencies.

Additionally, Flow Science remains up-to-date with the current modeling and policy developments in the Bay-Delta area, including the complicated CALFED process.
