This page has been planned for future development.
In the mean time, refer to the user guide for details on working with rivers in Source. The following sections explain how to configure the various river water quantity processes in Source:
- Nodes - refer to the child pages for a description on each of the nodes;
- /wiki/spaces/SD550/pages/521929601; and
- Groundwater interaction module.

Alternatively, contact us on support@ewater.com.auRiver systems are schematised into a simplified river network using a node-link structure for modelling in Source. The river network begins and ends with a node, and all nodes are interconnected by links. Runoff is fed into the network as an inflow at the relevant location in the network. Links represent a length of stream, which can be zero for near coincident processes, and are used for transfer of flow and constituents between two nodes with or without routing and transformation. Note that Source is generally a feed-forward model (from upstream to downstream), in that the only bi-directional flow is associated with the filling and emptying of wetlands, otherwise there are no bi-directional interactions with upstream elements. (Extracted from Welsh, et al, 2013, with adaptations to suit the needs of the SRG.)
Source provides functionality for routing of flows and water quality constituents, including decay and deposition, through links. More information on this functionality is available via Water quantity processes (Rivers) - SRG for flows and Link water quality processes (Rivers) - SRG for water quality, respectively. More information on processes modelled at nodes is available via Water quantity processes (Rivers) - SRG.
