This page has been planned for future development.
In the mean time, refer to the user guide for details on working with link water quality processes. The following section explains how to configure the groundwater interaction module in Source:

Alternatively, contact us on support@ewater.com.auWater quality is modelled in links and for certain node types (see Nodes SRG for more information on these).
Two approaches are provided for routing constituent movement through a reach. The first approach assumes the constituent is fully mixed within a reach. This approach can be appropriate where the user is interested in monthly or annual loads. A particle tracking method that is also provided routes the constituent at the velocity of flow (Close, 1996). This method is more accurate and is suitable where the user is interested in concentrations or loads at shorter time steps. More information on these is available via Routing Type SRG.
A range of options are available for representing simple in-stream processes in links. The in-stream models act on each constituent in the river, in a manner similar to the processing of each constituent by filter models. These comprise decay models (see Decay SRG) and modelling of surface water-groundwater exchange fluxes (see Flux SRG).
Simple storage nutrient and sediment deposition models have also been provided that can be used when modelling appropriate node types as well as links. More information on these is available via Decay SRG.
The above material has been sourced from Welsh, et al (2013) with adaptations to suit the needs of the SRG.
