Section 3 Process Descriptions
Previous chapters have presented an overview of the architecture and capabilities of the WQ Module, together with a summary of its interactions with TUFLOW FV. This chapter presents the details of each simulation class (see Table 2.1) in terms of its available model classes, the constituent models within those model classes, and the associated computed variables.
Process descriptions are listed in this section primarily by name in tables and networks, without inclusion of detail. This is for clarity, with the detailed process descriptions and equations being provided in the Appendices. To facilitate this linkage with supporting material, each process tabulated in this section has been hyperlinked directly to the relevant Appendix, and these hyperlinks colour coded as
Again for clarity, potential interactions of a computed variable with higher order computed variables (for example oxygen with phytoplankton) are included in this section only in descriptions of those higher order variables and processes. Further:
- Where a computed variable’s process is modified by a lower order computed variable (e.g. silicate sediment flux modified by oxygen), then the lower order computed variable name is shown diagrammatically in a contrasting style overlying relevant process arrows in network diagrams
- Where a computed variable or process directly modifies a lower order computed variable (e.g. phytoplankton respiration consumes dissolved oxygen) then the lower order computed variable is explicitly included in tables and networks
- Computed variables listed in the tables are hyperlinked to supporting information in Appendix P
- Optional model classes (such as pathogens) are not included in the simulation class conceptual images (such as Figure 3.1) for clarity, but are first described in the simplest simulation class for which they can be deployed. Optional model classes are included in simulation class network diagrams only if they directly influence other water quality computed variables (e.g. pathogens do not, so are excluded from broader network diagrams).
The manual’s introduction should be reviewed for guidance on the use of interactive components deployed in this section.
