The AD module simulates the advection and dispersion of conservative constituents in the water column. It has the following features:
- Drivers are the TUFLOW FV hydrodynamic field (2D or 3D)
- 1st and 2nd order AD schemes
- Essentially unlimited number of AD parameters / constituents
- Option to apply decay rates
- Inclusion of heat budget and atmospheric exchange routines for detailed temperature modelling
- For the 3D module, inclusion of baroclinic effects due to variations in salinity, temperature and suspended sediment concentrations
The ST module simulates sediment transport processes, including:
- Sediment transport in the water column through vertical mixing, horizontal advection and diffusion
- Sediment exchange with the bed through settling and re-suspension
- Tracking of multiple sediment fractions
- Morphology evolution feedback into hydrodynamics
- Special routines to simulate dredge plume generation
The 3D Module is a fully three-dimensional model that assumes a hydrostatic pressure distribution in the water column, including baroclinic terms.
When run in 3D, TUFLOW FV has the ability to simulate temperature, salinity and density stratification in order to fully resolve baroclinic (density) driven processes. Linked with this ability is a capability to accept and respond to atmospheric forcing parameters and heat transfer processes (including air temperature, relative humidity, long and short wave radiation and wind speed and direction).
The water quality module couples TUFLOW FV with the Aquatic EcoDynamics (AED) model to simulate aquatic biogeochemical and ecological dynamics. It has been developed in response to recognised deficiencies in existing water quality approaches used around the world, and it supports a common library of biogeochemical and ecological ‘components’.
AED has been built by A/Prof Matthew Hipsey and his team at the University of Western Australia. It includes the ability to simulate interactions between biogeochemical variables including oxygen, carbon, nutrients (organic and inorganic), sediment, light, temperature and algal species.
