TUFLOW’s Advection Dispersion (AD) Module is an extension of the TUFLOW Classic/HPC engines. It adds to the hydrodynamic capabilities of TUFLOW Classic/HPC by simulating depth-averaged, two and one-dimensional constituent fate and transport. An example of such a constituent might include salinity. Both dissolved and particulate constituents can be simulated. TUFLOW AD takes depth and velocity fields computed by the TUFLOW Classic and HPC solvers and uses this information, together with initial and boundary conditions, to simulate the advection and dispersion of user-defined constituents.
TUFLOW AD is specifically oriented towards such analyses in systems including coastal waters, estuaries, rivers, floodplains and urban areas. The AD module is discussed in detail in the <u>[https://docs.tuflow.com/classic-hpc/manual/

Line 101:
Pollutants can be generated based on modelled bed shear stress, then transported through the domain using the flow field. The model can also apply decay and settling rates as part of the simulation.
The TUFLOW CATCH module is recommended to simulate pollutant runoff and transport from catchments. See the <u>[https://www.tuflow.com/products/tuflow-catch-module/ TUFLOW Website]</u> for further information.
