The Data Sources toolbar allows you to add and manage sources of data (time series or by linking to another scenario). You can edit or view this data once it has been loaded in the Data Sources Explorer.
File toolbar
The File toolbar contains commands for creating a new project, opening an existing project, and saving a project (and all the scenarios within that project)project (and all the scenarios within that project).
Function manager toolbar
The Function manager toolbar allows you to add and manage all functions and expressions in Source.
Project toolbar
The Project toolbar allows you to hide or display the Project Explorer, Recording Manager, Log Reporter and Chart Recording Manager. To hide or display any of these windows, click the relevant button in the toolbar.
...
To create an Operations scenario, first create a River Manager scenario. Then, choose to open the River Operations dialog.
Opening a scenario
When a project only contains one scenario, that scenario is opened automatically when you open the project. However, when a project contains more than one scenario, you must open each scenario individually.

Note: You cannot use an earlier version of Source to open a project that was saved by a later version. |
Copying a scenario
You can duplicate existing scenarios. You may want to do this if you wish to experiment with variations without affecting your original scenario.
...

If you save a project in the folder where Source Source is installed, the project may be removed during any an un-install procedure. |
Editors
Source uses editors which are tailored to the needs of the main scenario types. There are three main editors, known as the Geographic, Schematic and Tabular editors, which support the catchments, management and operations scenario types respectively. These editor-scenario type associations are not absolute and you will often use multiple editors within a given project. For example, you can use the Schematic Editor to define the model of a river system for both operations and management scenario types. The next section provides an overview of each of them.

Note: Catchment runoff is fed into links, so deleting a link that is associated with a catchment effectively stops that catchment runoff from entering the system. When this happens, the catchment boundary is highlighted to indicate that the catchment is disconnected from the network. Follow the steps listed to reconnect the catchment to the network. |
You can also set geolocation coordinates and elevations for nodes and reaches using the Location Control window (using View » Location Control, as shown in figure 12). While it is not essential, it is conventional to set elevations with respect to Australian Height Datum (AHD). You can enter negative numbers for components that are below sea level, such as the lower lakes of the Murray. The elevation of a component is the zero point for that component. For example, the zero point for a storage is the lowest point in the storage.

- You can work with links and nodes in the Schematic Editor using Allow Link Dragged. This button allows you to disconnect the downstream end of a link from the node to which it is attached, and then reconnect that link to the upstream inlet of another node. You can use this feature to insert new nodes into a schematic without losing the configuration of existing links.
- Straight Lines controls the representation of links. Source defaults to drawing links using orthogonal (elbow) lines. Click this button to change the default representation to straight lines. The top-left schematic in Figure 13 shows how a model will be represented after you press this button. The representation of any link can be controlled independently using the contextual menu in the Schematic Editor. Right-click the link and choose one of the options in the Link Type sub-menu. Each line has one control point which you can adjust to route the line around obstacles. The control point for an orthogonal line can only be moved in the vertical dimension whereas the control point for a straight line has no restrictions on its movement.
- Node Labels controls whether the names of nodes are shown in the Schematic Editor. Source defaults to displaying node names. The schematic on the right of Figure 13 shows the behaviour of the Schematic Editor with the Node Labels control turned on.
- Link Labels controls whether the names of links are shown in the Schematic Editor. Source defaults to displaying link names.
- Track (Schematic Editor options toolbar) controls whether the Schematic Editor always scrolls to show components as they are selected in the Project Hierarchy. The default state of this button is off. In this mode, Source leaves the Schematic Editor window unchanged, regardless of any selections you may make in the Project Hierarchy. If you turn Track on, the Schematic Editor window will scroll to bring into view any node or link that you select in the Project Hierarchy. You can use this feature to locate components in large models.
- Overview Panel controls whether the Overview Panel is shown in the Schematic Editor. The default state of this control is off. The schematic on the bottom left of Figure 13 shows the behaviour of the Schematic Editor with the Overview Panel control turned on. You can use this button to obtain a thumbnail view of your entire schematic. You can drag the Overview Panel to any point within the Schematic Editor but you cannot pan the Schematic Editor by dragging within the Overview Panel.
- Pan - controls movement of the drawing surface. When this button is enabled, clicking and holding on any part of the drawing surface in the Schematic Editor moves the entire drawing surface. This is an alternative to using the scroll bars;
- Tool tips - controls the view of tool tips containing information about a node’s order in the flow sequence, its elevation and the node type. A storage node contains additional information including its height, capacity and surface area:
Tool tips on – when selected, clicking on any node in the Schematic Editor causes a small floating window to appear which contains additional information about that node;
Tool tips off – when selected, the floating windows do not appear; and
Tool tips locked – when selected, clicking any node in the Schematic Editor causes a small floating window to appear next to every node.

Tabular Editor
The Tabular Editor provides a spreadsheet-like representation of data that is otherwise presented in graphical form in the Recording Manager.
Customising the Tabular Editor
You can customise the Tabular Editor to your needs. For each type of node or link, you can select:
- A background colour for the cell;
- A foreground colour and stylistic variation (eg. bold-face) for values displayed in the cell; and
- The number of decimal places to be displayed.
...
- By adjusting a set of user preferences. See Tabular Editor Formatting. Changes made via this method apply to all projects; or
- By right-clicking a column heading and choosing Column Formatting (refer to Column formatting). Changes made via this method only apply to the current project.
Column formatting
In this window, the Multiple Expressions tab (as shown in Figure 16) allows you to apply conditional formatting to cells in the tabular editor to highlight when thresholds or rules are breached eg. Flow < 500 ML/day. More than one expression can be applied to a cell. Click Add to specify the details of an expression, and Edit to define the expression using an Expression Editorthe Function editor. When more than one condition is satisfied, the cell is formatted as per the left side of the panel. Hover the mouse over the cell with the conditonal conditional format, and the expression name is displayed. Click Remove to delete an expression from the list.

The Data Sources tab allows you to view and manage time series at one location in Source. When time series are added using the Data Sources Explorer, they are available for use throughout Source. For more details on using this, refer to Importing data.
Function Manager
The Function manager panel allows you to create, manage and maintain all functions and expressions defined in Source. Just as all data in the Data Sources Explorer is available throughout Source, all functions and expressions added in the Function manager can be used in the same way.
Node Palette
The Node Palette contains a list of icons representing the nodes that are supported by Source. To create a node-link network, drag icons from this palette onto the Schematic Editor’s drawing surface.
...
Many feature editors support loading parameter information from a file. Where present, the Import... button can be used to load parameters into a feature editor whereas the corresponding Export... button will save the table’s current values to an external file. Additionally, as an alternative to entering or importing discrete parameter settings, the feature editors for many nodes allow for the node’s behaviour to be defined via an arithmetic expression or function (refer to Expression Editor Function manager).
