Renumber Interconnected Diversions Command

The Renumber Interconnected Diversions command allows the user to automatically renumber diversion structures and connected routing reaches along a defined flow path.

Follow the steps below to use the Renumber Interconnected Diversions command:

From the Input ribbon menu, click the Diversions dropdown menu and then select the Renumber Interconnected Diversions command.
The Renumber Interconnected Diversions dialog box will be displayed.

The following sections describe the Renumber Interconnected Diversions command and how to interact with the above dialog box.

Selecting Reaches

The Select Reaches panel is used to select all the reaches that define a flow path.

Selecting Multiple (Interconnected) Reaches

The Select Multiple (Interconnected) Reaches section is used to sequentially number reaches and diversions along the selected flow path that has reaches connected end-to-end with each other.

The user can click the [Pick] button and select the downstream most and upstream most reach on the Map View, and the software will automatically determine all connected diversions and reaches between them that make up the river path.

If a reach is already selected on the Map View prior to running this command, the same reach will be shown selected within the table.

Alternatively, the user can click the [Pick] button to manually select the reaches from the Map View. On clicking the [Pick] button, the Renumber Interconnected Diversions dialog box will temporarily disappear, and a prompt will be displayed on the status bar instructing the user to select the reaches from the Map View. After selecting the reaches, the user can press the [Enter] key or right-click and choose Done from the displayed context menu. The Renumber Interconnected Diversions dialog box will be redisplayed, and the total number of selected reaches will be displayed in the Total selected read-only field.
Selecting multiple (interconnected) reaches

Note that the user can select multiple reaches from the Map View prior to running the Renumber Interconnected Diversions command by holding the [Ctrl] key while selecting the desired reaches.

Manual Editing

This section contains a data grid that lists the IDs of the selected reaches and diversions. The data grid also lists the reach distance and total reach distance in miles and feet. The values in the last two columns of the data grid provide a preview of the reaches and diversions naming specifications defined in the Diversion Renumbering and Reach Renumbering panels.

Diversion Renumbering

This panel allows the user to number diversions based upon diversion stationing or incrementally.
Diversion Renumbering panel

Diversion Stationing

This section is used to define diversion stationing. Diversions can be numbered using a fixed increment or by the river chainage along the river reach. The river chainage can be in miles or feet if working in US units, or kilometers or meters if working in metric (SI) units.

The following options are provided in this data panel:

Diversion ID prefix: This option allows a prefix to be added to the start of the diversion ID.
Diversion ID suffix: This option allows a suffix to be added to the end of the diversion ID.
Diversion ID preview: This entry provides a preview of the diversion naming specifications defined above.
Numbering direction: This dropdown combo box defines the direction in which the diversion IDs are increasing. The following options are available:
1. 1. Increasing Downstream
  2. Increasing Upstream (HEC-RAS style) (default)
Based on the option selected, the content of the Use reach distance radio button subsection will be changed.

Use Reach Distance

This subsection is used to number the diversion by using the river chainage along the river reach. The following entries are provided:

Downstream diversion ID: This entry provides a diversion ID that will be used as the downstream most river station.
Note that if the Increasing Downstream option is selected in the Numbering direction dropdown combo box, then the Downstream diversion ID entry will change to Upstream diversion ID, as shown below. In addition, the numbering methodology will be altered to account for the selected direction.
Upstream diversion ID: This entry provides a diversion ID that will be used as the upstream most river station.
Distance units: This dropdown combo box defines the unit for the reach length. Two available options are:
1. Feet
2. Miles

Decimal precision: This optional checkbox defines the decimal precision that will be used in determining the diversion river stations. By default, this checkbox is unchecked. If checked, then the user can enter a value ranging from 0 to 15.

Use Auto Increment

This subsection is used to number the diversion using a fixed increment. The following options are provided:

Diversion ID digits: This option permits the specification of a set number of digits to use for the diversion ID. For example, using 3 digits causes the diversion ID to be of the format 001, 002, etc.
Next available diversion ID: This entry defines the next element ID number to be used.
Diversion ID increment: This entry defines the increment to use when numbering elements. The default value is 1.

Previewing Diversion ID

Clicking on the [Preview] button causes the software to fill the diversion IDs in the New Diversion ID column of the Manual Editing data grid.

Reach Renumbering

This panel allows the user to number the reaches based upon river chainage or incrementally. By default, the Reach Renumbering checkbox panel is checked. If the panel checkbox is unchecked, then the content of this panel will be disabled and the reach will not be renumbered.

Reach Stationing

This section is used to define the river stationing to be used for the constructed reaches.

The following options are provided in the data panel:

Reach ID prefix: This option allows a prefix to be added to the start of the reach ID.
Reach ID suffix: This option allows a suffix to be added to the end of the reach ID.
Reach ID preview: This entry provides a preview of the reach naming specifications defined above.
Numbering direction: This dropdown combo box defines the direction in which the reach IDs are increasing. The following options are available:
1. 1. Increasing Downstream
  2. Increasing Upstream (HEC-RAS style) (default)
Based on the option selected, the content of the Use reach distance radio button subsection will be changed.

Downstream reach ID: This entry provides a reach ID that will be used as the downstream most river station.
Note that if the Increasing Downstream option is selected in the Numbering direction dropdown combo box, then the Downstream reach ID entry will change to Upstream diversion ID. In addition, the numbering methodology will be altered to account for the selected direction.
Upstream reach ID: This entry provides a reach ID that will be used as the upstream most river station.
Distance units: This dropdown combo box defines the unit for the reach length. Two available options are:

Use Auto Increment

The Use auto increment subsection is used to number the reach using a fixed increment. The following options are provided:

Reach ID digits: This option permits the specification of a set number of digits to be used for reach ID. For example, using 3 digits causes the reach ID to be of the format 001, 002, etc.
Next available reach ID: This entry defines the next element ID number to be used.
Reach ID increment: This entry defines the increment to use when numbering elements. The default value is 1.

Previewing Reach ID

Clicking on the [Preview] button causes the software to fill the reach IDs in the New Reach ID column of the Manual Editing data grid.

Renumbering Diversions and Reaches

When the data have been defined in the Renumber Interconnected Diversions dialog box, click the [Apply] button. The software will then renumber the IDs of the diversions and reaches along a defined flow path.
